This application claims priority to Italian Patent Application 102017000122588 filed Oct. 27, 2017, the entirety of which is incorporated by reference herein.
The invention relates to an apparatus and a method for analysing samples taken by biopsy, which make it possible to perform the analysis of these samples whilst the patient is still positioned in the position for taking samples, in such a way as to make the overall procedure for taking and analysing the samples faster, reducing the inconvenience for the patient and the risk of a new examination, and also reducing in the majority of cases exposure of the patient to X-rays.
Currently, in order to the perform the bioptic taking of lesions identified as suspicious in the body of the patient, one of the possibilities when the lesion is radiopaque is the use of an apparatus for the X-ray analysis of at least a part of the body of the patient, by which a research of the suspicious lesion in this part of that body of the patient is performed. When the suspicious lesion has been found in the X-ray image, its position is determined by means of further X-ray images (pointing) and a step of taking one or more samples by means of a biopsy is performed, in order to sample a part or all of the suspicious lesion, in order to subsequently analyze by cytological or histological examination.
During the step for taking samples by means of biopsy or at least before the demission of the patient it is good practice to carry out a check by X-ray of the samples already taken to confirm that the sample contains the same anatomic element considered suspicious in the image of the patient and that the procedure for determining the position of the lesion and for its sampling has therefore been successfully completed. In the case of unforeseen events, this checking allows an immediate repetition of the pointing, without having to arrange a new appointment for the patient and it reduces the risk of diagnostic errors from the biological analysis of the sample due to incorrect sampling. The X-ray checking may be performed using a further apparatus specifically for this purpose or by means of the same type of apparatus with which the suspicious lesion has been identified, but always separate with respect to the apparatus with which the pointing is performed.
The aim of this invention is to provide an apparatus and/or a method for the analysis of samples taken by biopsy, which allows the analyses to be performed with the same apparatus with which the pointing and sampling is performed when the patient is still in the position for taking the samples, and also without requiring the patient to adopt an uncomfortable position during the analysing step or having to withdraw the needle for taking the samples from the patient.
In addition to the benefit for the patient, the use of the same system for both the procedures (the one of pointing with subsequent taking and checking of the samples) is a guarantee of the same quality of result and thus of consistency between the results of the two analyses (identifying the target for taking and checking the presence of the target in the sample taken).
Another aim of this invention is to provide an apparatus and/or a method for the analysis of samples taken by biopsy which allows these analyses to be performed when the patient is still is in the position for taking the samples and limiting (for example, minimizing or avoiding completely), during the step of analysing the samples performed by means of the apparatus, an unnecessary exposure of the body of the patient to X-rays.
These aims are achieved by an apparatus having features as disclosed herein or by a method having features as disclosed herein.
The features of an apparatus according to this invention and of a method according to this invention will become clearer from the detailed description below relating to a possible embodiment of the apparatus and to a possible embodiment of the method, given by way of non-limiting examples of the concepts claimed.
The following detailed description refers to the accompanying drawings, in which:
In the accompanying drawings the numeral 1 denotes a possible embodiment of an apparatus according to the invention. The apparatus 1 is configured for the analysis of samples. These samples are to be considered as taken from a part of the body of a person.
The apparatus comprises a support 11 for these samples. The support 11 defines a supporting surface 111. The supporting surface 111 is designed for positioning the samples on the supporting surface 111.
The apparatus 1 comprises a system 12 for generating a field of X-rays. The generating system 12 is configured for generating the field of X-rays.
The generating system 12 is configured so that the field can adopt a plurality of different operating conditions.
The apparatus comprises an X-ray detector 13. The detector 13 defines a detection surface 131. The detector 13 is configured to detect the image of X-rays incident on the detection surface 131. The apparatus 1 is configured in such a way that, when the field adopts any of the operating conditions, the X-rays of the field strike the detection surface 131 after striking the supporting surface 111. In that way, also by means of the configuration of the support 11, the apparatus 1 is configured in such a way that, when the field adopts any of the operating conditions and any object any is positioned inside the field and on the supporting surface 111, the apparatus 1 can perform, by means of the generating system 12 and the detection system 13, an acquiring of at least one X-ray image of the any object.
Since the any object can be considered as a corresponding to the above-mentioned samples, this means that the apparatus 1 allows the acquiring of at least one X-ray image of the samples, whilst they are positioned on the supporting surface 111 and inside the field.
The generating system 12 is configured so that the operating conditions differ from each other for the orientation and/or the position of the field of X-rays with respect to the detection surface 131 and/or for at least the value of a dimension of the field of X-rays.
In an example use of the apparatus 1, the field of X-rays can be considered as a cone of X-rays.
C1 in
In
It is possible to define a reference system integral with the detection surface 131. The reference system is defined by a set of three axes of which a first axis Z and a second axis Y are positioned and/or lying on the detection surface 131. The first axis Z and second axis Y are shown, by means of the respective versors, in
The third axis of the reference system, which is not shown in the drawings, is at right angles to the first axis Z and second axis Y.
To generate the field of X-rays, the generating system 12 comprises an X-ray source 121. The source 121 is schematically represented as a dot in
The source 121 can generate X-rays designed to give rise to the field of X-rays. To ensure that the field of X-rays can adopt one or other of the plurality of operating conditions, and therefore to ensure that it can adopt these operating conditions, the generating system 12 comprises a collimator and a movement system.
The movement system is labelled 23 in
A position of the source 121 with reference to the above-mentioned reference system integral with the detection surface 131 may be considered as a “position of the source 121 with respect to the detection surface 131”.
The generation system 12 is configured so that the movement system 23 can cause a movement of the source 121 in such a way that the source 121 can adopt a plurality of different positions relative to the detection surface 131.
In
This movement of the source 121 may be performed, for example, along a curved trajectory.
The generation system 12 is configured so that the collimator can adopt a plurality of operating configurations associated with a plurality of collimation modes respectively. Each of the respective plurality of collimation modes is associated with a respective one of the operating configurations of the collimator and derives from the fact that the collimator adopts the respective operating configuration. The generation system 12 is configured so that the collimator can follow the movement of the source 121. The generating system 12 is configured so that, when the collimator adopts any one of these operating configurations, and when the source 121 adopts any one of these positions of the source 121 relative to the detection surface 131, the collimator is adjusted to allow the passage of the X-rays emitted by the source 121 in accordance with the collimation mode with which the operating configuration adopted by the collimator is associated, in such a way as to define the operating condition adopted by the field of X-rays. As a result, each of the operating conditions of the field is defined by a respective combination of one of the positions of the source 121 and of one of the configurations of the collimator. The variation of the operating configuration of the collimator, if the field is considered as a cone X-rays, can determine a variation at least of the angle of the cone and/or a variation at least of the orientation of the cone relative to the detection surface 131. The variation of the position of the source 121 relative to the detection surface 131 can determine a variation at least of the orientation of the cone relative to the detection surface 131.
The difference between the first operating condition of the field, labelled C1 in
The apparatus 1 comprises a support 14. The support 14 defines a supporting surface 141 for resting the above-mentioned part of the body of a person on the supporting surface 141. The support 11 can be also defined as a “first support 11” and the support 14 can be also defined as a “second support 14”. Therefore, the supporting surface 111 can be also defined a “first supporting surface 111” and the supporting surface 141 can be also defined a “second supporting surface 141”.
The apparatus 1 is configured in such a way that, when the field adopts any of the operating conditions, the X-rays of the field strike the detection surface 131 after striking the supporting surface 141. In that way, also by means of the configuration of the support 14, the apparatus 1 is configured in such a way that, when the field adopts any of the operating conditions and the part of the body is positioned inside the field and on the supporting surface 141, the apparatus 1 can perform, by means of the generating system 12 and the detection system 13, an acquiring of at least one X-ray image of the part of the body.
The acquiring of at least one X-ray image of the part of the body may be aimed at identifying a possible area of the part of the body in which a lesion or suspicious mass could be positioned.
In the embodiment illustrated, the detector 13 is integrated in the support 14.
In the embodiment illustrated, the detection surface 131 may be in a fixed position relative to the supporting surface 141.
In the embodiment illustrated, the support 11 coincides with the support 14, in such a way that the supporting surface 111 coincides with the supporting surface 141. In the light of the above, in this case, the first support 11 coincides with the second support 14 and the first supporting surface 111 coincides with the second supporting surface 141.
The supporting surface 111 might, however, not coincide with or be completely separate from the supporting surface 141. The support 11 might not coincide with or be completely separate from the support 14.
The support 11 could be removable from the remaining part of the apparatus 1.
The apparatus 1 comprises a biopsy probe 16 in order to take the above-mentioned samples from the above-mentioned part of the body of a person.
The probe 16 may comprise a sampling element 161 to perform the sampling. The probe 16 may comprise a support 162 to support the sampling element 161. The sampling element 161 may be a needle.
The sampling may be a biopsy. In this case, the samples are to be considered as taken by biopsy.
The apparatus 1 is configured so that the probe 16 can be subjected to a movement through the field and/or relative to the detection surface 131. The movement of the probe 16 is used to ensure that the position which the probe 16 adopts whilst taking the samples is as correct as possible in order to increase the probability that the samples belong to the above-mentioned lesion or suspicious mass.
The step during which the probe 16 moves to increase the probability that the samples subsequently taken belong to this lesion or suspicious mass may be defined as “pointing”. The pointing is basically guided by the X-ray images of the part of the body which have been previously acquired for identifying the above-mentioned possible zone of the part of the body in which this lesion or suspicions mass could be positioned.
The above-mentioned acquiring of at least one X-ray image of the samples whilst they are positioned in this field and on the support 11, is aimed at check that the samples actually belong to this lesion or suspicious mass.

The movement of the probe 16 could comprises at least a rotational component. The rotational component is a rotation on itself of the probe 16. The rotation occurs about an axis of rotation which remains integral with the above-mentioned translational component of the movement of the probe 16. The projection of this rotation on the plane of

The apparatus 1 is configured so that the stabilizing element 15 can be subjected to a movement through the field and/or relative to the detection surface 131. This movement of the stabilizing element 15 is used to ensure that the stabilizing 15, as a function of the shape and/or the size and/or the positioning of the part of the body on the supporting surface 141, can stabilize optimally the part of the body on the supporting surface 141, in order to take the samples from the part of the body.

The obtaining by the selection system 17 of the current position of the probe 16 may be considered as comprising at least one obtaining by the selection system 17 of the current value of the orientation of the probe 16.

The selection system 17 may comprise one or more sensors for detecting the at least one parameter, in order that the selection system 17 can obtain or know the at least one parameter.
The selection system 17 could comprise a first sensor 18, indicated in

The selection system 17 is configured to perform automatically, as a function of the at least one parameter, a selection of one of the operating conditions of the field.
The operating condition selected is associated with a selected surface portion of the supporting surface 111. The selected surface portion is to be considered as the surface portion of the supporting surface 111 on which the field strikes when it adopts the selected operating condition.
The selected surface portion is to be understood in the sense that, when the field adopts the selected operating condition, to perform an acquiring of at least one X-ray image of the samples by means of the field and whilst the samples are positioned on the supporting surface 111, it is necessary to position these samples on the selected surface portion of the supporting surface 111, in such a way that are in the field.
The selection system 17 is configured for performing the selection in such a way as to limit, when the field adopts the selected operating condition and the samples are positioned inside the field and on the supporting surface 111 (and in particular on the above-mentioned selected surface portion of the supporting surface 111), the influence of the at least one parameter on the accuracy of the acquiring, by means of the generating system 12 and the detection system 13, of at least one X-ray image of the samples.
The selection system 17 is configured to calculate and/or derive, as a function of the at least one parameter and for each of the respective operating conditions of the field of X-rays, the possible influence of the at least one parameter on the accuracy. The selection system 17 is configured to derive and/or to calculate, as a function of the at least one parameter, the interference of the at least one parameter with the field of X-rays, for each of the operating conditions which the field may adopt. In this way the selection system 17 can select the operating condition so that, when the field adopts the selected operating condition and the samples are positioned in this field and on the supporting surface 111 (and in particular on the above-mentioned selected surface portion of the supporting surface 111), the influence of the at least one parameter on the accuracy of acquiring at least one X-ray image of the samples is minimal or in any case limited.
The accuracy of the acquiring of at least one X-ray image of the samples means the degree of precision and/or accuracy with which the at least one image allows the physical characteristics of the samples to be analyzed. An unwanted interference of the probe 16 or of the stabilizing element 15 with the field of X-rays, when the acquiring of the at least one X-ray image of the samples is performed, may worsen the degree of precision and/or accuracy with which the at least one image allows the physical characteristics of the samples to be analyzed.
The fact that the field of X-rays, when the acquiring of the X-ray image of the samples is performed, passes through the stabilizing element 15, is not necessarily and an unwanted interference. It should be noted, in effect, that it is especially the edge zones of the stabilizing element 15, which respectively define the mutually opposite ends of the stabilizing element 15 along the first axis Z, that can, if they interfere with the field, significantly reduce the degree of accuracy and/or precision.
The selection system 17 is configured to generate a signal designed to signal to a user the selected operating condition. This signal comprises the highlighting on the above-mentioned selected surface portion.
The highlighting may comprise a signal, for example luminous, coming or generated from the selected surface portion.

The control signal can be, for example, that labelled “k” in

The selection system 17 could be configured so that the fact that the above-mentioned selection is performed as a function of at least the current position of the stabilizing element 15 or is not performed as a function of the current position of the stabilizing element, depends on the dimensions of the stabilizing element 15.

The selection system 17 could be configured so that the selection, if it is not performed as a function of the current position of the stabilizing element 15, is performed at least as a function of the current position of the probe 16.
The apparatus 1 could also be configured so that, even if the selection is performed as a function at least of the current position of the stabilizing element 15, the selection is performed in any case also as a function at least of the current position of the probe 16.
The selection system 17 could be configured so that the fact that the above-mentioned selection is performed as a function of at least the current orientation of the probe 16 or is not performed as a function of the current orientation of the probe 16, depends on the current height of the probe 16.

In this possible example embodiment of the apparatus 1, the selection system 17 is configured so that, if the current height of the probe 16 lies in a predetermined range of values, the selection is performed not as a function also of at least of the current orientation of the probe 16, and, if the current height of the probe 16 does not fall in this predetermined range of values, the selection is performed as a function also of at least of the current orientation of the probe 14.
The selection system 17 is configured to perform a logic process in order to perform the selection. The selection system 17 is configured so that the selection is performed by the processing unit 171. The processing unit 171 is programmed and/or configured to perform this logic process.

The apparatus 1 may comprise at least one container for containing the samples.
The apparatus 1 may comprise a locking system configured to define a condition for locking the container on any surface portion of a group of predetermined surface portions of the supporting surface 111.
The group of surface portions may comprise, for example, the surface portions labelled P1 and P2 in
The locking system is configured so that, when the container adopts the locking condition, the container keeps the samples operatively positioned on the any surface portion of the group of surface portions.
In this way, the apparatus 1 can be used even if the supporting surface 111 is parallel or in any case not at right angles to the force of gravity, and therefore whilst the patient, from whom the samples have been taken, it is in the prone position.
The selection system 17 is configured so that the selection is performed so that the selected surface portion belongs to the above-mentioned group of predetermined surface portions.
It should be noted that the selection system 17 could also be configured for reaching the conclusion that the analysis of samples, on the basis of one or more of the above-mentioned parameters, is impossible.
It should be noted that the selection system 17 could be configured to perform the selecting as a function at least the dimensions of the probe, as well as its position and/or orientation.
It should be noted that the selection system 17 could be configured so that the above-mentioned selection is performed solely as a function of one of the above-mentioned conditions because the other conditions are not significant for the accuracy of the acquiring. For example, the system could be formed in such a way that the position of the probe never interferes with the field of X-rays defined by the operating conditions corresponding to the above-mentioned predetermined surface portions. The checking of this condition is implicit in the selection system 18 and is always performed during the definition of the method even if not actively considered by the processing unit 171.
