This application claims priority to Italian Patent Application IT102021000028373 filed Nov. 8, 2021, the entirety of which is incorporated by reference herein.
This invention relates to a medical apparatus for X-ray analyses.
There are known medical X-ray apparatuses which comprise a source configured to emit X-rays and a detector configured to receive the X-rays emitted by the source.
Such apparatuses can be machines to perform, for example, mammography, tomosynthesis, breast CT, biopsies, CESM.
In order to perform the above-mentioned medical tests, the patient's breast is interposed between the X-ray source and the detector.
In this way, the breast may be passed through by the X-ray radiation which has been emitted by the source, so that the image of the breast is generated on the detector.
Some apparatuses are designed to allow examinations with the patient in a vertical position in such a way that the procedure is easy for the patient, for breasts of any size.
Prior art systems, which are generally apparatuses dedicated specifically to a particular examination, have a supporting table for the patient so as to perform an examination in a prone position.
The prone position allows the operators to work in a more comfortable manner around the patient and to reduce the occurrence of vasovagal reactions, that is, fainting, in particular for performing the biopsy.
However, the vertical position may be uncomfortable to maintain, or even impracticable, for elderly or disabled patients.
Moreover, an examination with the patient in a vertical position may be less comfortable for the operators.
At the same time, however, for these patients, the prone position may also be difficult, or even impossible, to be achieved due to any limitations to the motor functions.
A need felt in the trade is to speed up and facilitate the positioning of the patient for examinations performed using X-ray medical apparatuses.
An aim of the invention is to provide an apparatus for X-ray examinations which overcomes the above-mentioned drawbacks and satisfy the above-mentioned need.
More specifically, an aim of the invention is to provide an apparatus for X-ray medical examinations which improves the speed, ease and comfort of the procedures for positioning the patient for these examinations.
Another aim of the apparatus for X-ray examinations described in the invention is to ensure ease of operation of the apparatus for the operators who operate it.
A further aim of the invention is to provide an apparatus for X-ray examinations which guarantees a high level of safety during these examinations both to the patient and to the operators in charge.

It should be noted that the machine 40, once the support device 10 has been detached from it, can be adapted easily and extremely quickly also for other examinations, in particular its configuration may be modified, by moving, for example, the supporting frame 43 between a first operating position P3 and a second operating position P4 to allow a diagnostic examination to be performed in the second operating position P4. This aspect is described in more detail below, where the advantages connected to the mobility of the supporting frame 43 may be inferred in a clearer manner.
Advantageously, a removable coupling between the support device 10 and the base frame 49 makes it possible to make the maintenance and transport operations of the machine 40 and/or of the support device 10 more comfortable since they can be performed individually.
Advantageously, the removable coupling between the support device 10 and the base frame 49, together with the possible inclination of the supporting frame 43 between a first and a second operating position (P3, P4) and of the inclinable portion 11 at various angles, makes it possible to quickly pass from a configuration of the apparatus 1 for mammography/tomography with the patient standing to one in which to perform, for example, a Cone Beam Breast Computed Tomography (CBBCT) with the patient in the prone position.
The coupling means 30 may be, for example, mechanical or magnetic.

According to a preferred embodiment, as illustrated in
The supporting frame 43 can be inclined by rotating about the axis of inclination A1 and rotated about the axis of rotation A3.
It should be noted, for a more immediate understanding, that when the supporting frame 43 rotates about the axis of inclination A1, the axis of rotation A3 also rotates in an integral fashion, relative to the supporting frame 43, about the axis of inclination A1.
Advantageously, rotating the supporting frame 43 about the axis of rotation A3 makes it possible to perform examinations, such as, for example, the CBBCT, which require the rotation/oscillation of the X-ray source 41 as one with the X-ray detector 42.

The anti-collision sensors are configured to detect the contact between the detector 42 and any other element and to send a signal to the control unit U when the contact occurs.
The control unit U is configured to receive the signal and block each movement of the apparatus 1.
In other words, the control unit U, when it receives from the anti-collision sensors the signal of contact between the detector 42 and any other element, prevents the movement of each of the components of the apparatus 1.
Advantageously, blocking each movement of the apparatus 1 when the anti-collision sensors detect a contact makes it possible to avoid any unplanned impact or compression of the breast which may cause pain to the patient.
Advantageously, locking each movement of the apparatus 1 significantly increases the safety of the patient since it prevents any injury, even serious injuries.
It should be noted that the procedure for protection of the patient is particularly suitable for examinations such as CBBCT which requires rotation of the detector 42 around the breast.
Advantageously, this automated protection procedure makes it possible to keep the detector at a minimum distance from the breast, thus optimising the breast imaging system, while also maintaining the safeguard of not causing pain to the patient even against drawbacks.
According to an aspect, the anti-collision sensors are distance sensors configured to detect the distance between the detector 42 and any other element.
According to an aspect of the invention, the apparatus 1 comprises at least one calibration body 23.
The at least one calibration body 23 is removably coupled to the inclinable portion 11 of the support device 10.
Advantageously, the at least one calibration body 23 allows the support device 10 to be positioned in an optimum manner relative to the machine 40.
In particular, the at least one calibration body 23 allows the opening 13 to be correctly positioned relative to the axis of rotation A3.
According to an aspect of the invention, the graphical marking elements, described above, operatively act in conjunction with the at least one calibration body 23.
It should be noted that in the normal diagnostic procedures it is worthwhile periodically calibrating the positioning of the support device 10, and in particular of the opening 13 of the inclinable portion 11 relative to the machine 40.
In particular, this calibration is often required when the machine 40 is reactivated following a switching off.
The need for a calibration may also be necessary following a movement of the apparatus 1 or a part of it.
According to the invention, the control unit U comprises a user interface, not illustrated in the accompanying drawings.
Advantageously, the user interface allows the operator to display, set up and control the commands of the apparatus 1.
In particular, thanks to the user interface, the operator is able to control the movement of the support device 10 and of the machine 40 and of each of their components.
Advantageously, thanks to the user interface, the operator can thus be automatically informed of the values measured by the sensors of the lifting plane 14 and/or by the movement sensors 24 and/or by the anti-collision sensors.
The X-ray analyses which the apparatus 1 can perform may be, for example, without limiting the scope of the invention, Breast CT, Cone Beam Breast CT (CBBCT), mammography, mammary tomosynthesis, CESM.
For example, in order to perform a CBBCT, the source 41 must be able to rotate together with the detector 42 about the breast by a predetermined angle, preferably between 120° and 240°, even more preferably between 150° and 220°, even better between 180° and 210°.
In that way, the cone-shaped X-ray beam emitted by the source 41 and absorbed by the detector 42 makes it possible to reconstruct a three-dimensional image of the breast by scanning in a single rotation around the breast.
The patient is positioned prone on the support device 10.
The 3D reconstruction is performed using software in the control unit U, which also controls the movement of the elements of the apparatus 1 both during positioning of the patient and during analysis during the diagnostic examination.
