The present invention relates generally to medical imaging systems, and more particularly to a method and system for reducing the anxiety level of a patient, particularly a pediatric patient, before and during the procedure in order to further reduce image artifacts attributable to patient motion during image data capture.
Medical imaging systems scan patients to obtain medical information, and involve several imaging modalities, including: computed tomography (“CT”), positron emission tomography (“PET”), combined CT and PET (“PET-CT”), single photon emission computed tomography (“SPECT”), X-ray, gamma camera imaging, magnetic resonance (“MR”), and others, including the combinations or hybrids thereof.
Medical images constructed (or reconstructed) from data acquired by the medical imaging equipment and/or systems are deleteriously affected by patient motion during the data acquisition phase and this is a well known problem. Image quality must be above a certain acceptable threshold to be considered useful for diagnosis or treatment. In the event the image is unacceptable for use or diagnosis the patient must be scanned again and a second dose of an imaging agent drug must be administered. This inefficiency is not merely burdensome and increasingly more traumatic for the child, it is a poor use of hospital resources, equipment and staff.
In order to reduce patient motion during an imaging procedure, the imaging system operator typically instructs the patient to remain substantially motionless while the imaging information is being acquired. However, involuntary motion encountered in medical imaging systems is also common and a source of image artifacts, and may be caused by numerous physiological parameters. For example, breathing motion, motion of the heart, e.g. accelerated heart rate, and/or motion involuntary motion of a head, arm, or leg of the patient. Increased patient anxiety is known to cause increases in some of the patient's involuntary physiological parameters such as the patients breathing or the patient's heart rate, resulting in increased patient movement during imaging.
Other patient motions that are not involuntary and yet not readily controllable by the patient are movements are particularly pronounced with the pediatric patient (i.e., children). This pediatric patient anxiety is often attributable to the intimidating look and overall appearance of the imaging system as viewed through the child's eyes regardless of the modality. Typically the imaging system is installed in a dedicated imaging room within a hospital or imaging center. In most of the rooms where the imaging equipment is installed, there are a variety of additional support systems and subsystems such as computers, telephones, general medical care devices such as blood pressure cuffs, furniture, equipment consoles, etc., which is just about anything supportive of the procedure or medical care in general.
While both the conventional imaging system and the conventional imaging system room are designed to improve the performance of the imaging system and to enhance the operation of the system by the medical personnel, the clinical appearance and smell, the unfamiliar shape and large size of the equipment, and associated operational sounds of it, etc., are known to cause anxiety and fear in pediatric patients undergoing the medical imaging procedure. In turn, the anxiety and fear exhibited by the child is manifested in both voluntary and involuntary motion including, but not limited to, elevated heart rates, rapid breathing, fidgeting, trembling, and nervousness resulting in unwanted body movement during image data capture.
To counteract voluntary and involuntary patient motion, physicians commonly administer sedatives to children to cause physical and mental relaxation of the child patient thereby minimizing patient motion enabling a better scan. In the pediatric setting, the sedation process itself also adds an element of fear and anxiety. While sedative injections or inhalants used for children are common in imaging procedures they are wholly undesirable. Wherever sedation is required, it is preferred to utilize the minimum required sedative to calm the patient, minimize patient motion attributed to anxiety and fear, etc., and perform the accurate imaging. The physician chooses the dosage of sedative to offset the patient's anxiety level.
Scientific studies have proven when pediatric patients are distracted from or desensitized to the conventional clinical imaging environment, the need for sedation noticeably and appreciably decreases while image quality, accuracy and efficiency improves.
Therefore, a need exists for a facility, an imaging system and a method to reduce pediatric patient anxiety and fear associated with medical imaging procedures in order to improve scan success and image quality while minimizing the use of sedatives.

The descriptions set forth above are exemplary and not intended to be limiting, and combinations or alternate embodiments thereof are considered to be within the scope of the present invention.
The foregoing summary and detailed description of certain embodiments of the present invention will be better understood when read in conjunction with the appended drawings. To the extent that the figures illustrate diagrams of the functional blocks of various embodiments, the functional blocks are not necessarily indicative of the division between hardware circuitry. Thus, for example, one or more of the functional blocks (e.g., processors or memories) may be implemented in a single piece of hardware (e.g., a general purpose signal processor or a block of random access memory, hard disk, or the like). Similarly, the programs may be stand alone programs, may be incorporated as subroutines in an operating system, may be functions in an installed software package, and the like. It should be understood that the various embodiments are not limited to the arrangements and instrumentality shown in the drawings.
In the exemplary embodiment, each of the medical imaging rooms includes a medical imaging system. For example, the first medical imaging room 14 includes a medical imaging system 20, the second medical imaging room 16 includes a medical imaging system 22, and the third medical imaging room 18 includes a medical imaging system 24. The medical imaging systems 20, 22 and 24 may be embodied as a computed tomography (CT) imaging system, a magnetic resonance imaging (MRI) system, a positron emission tomography (PET) imaging system, an ultrasound imaging system, an X-ray imaging system, or a single photon emission computed tomography (SPECT) imaging system.

The operation and control of the imaging system 10 may be performed in any manner known in the art. It should be noted that the various embodiments may be implemented in connection with imaging systems that include rotating gantries or stationary gantries.
With reference to
More specifically, as discussed herein, conventional imaging rooms and the conventional imaging system in it may cause a patient to experience an unpleasant emotion or fear in anticipation of the medical examination or procedure and while this is particularly common in young children, the present invention has been shown to minimize fear and anxiety of the patient overall, as well as to reduce the need for sedation in children. To facilitate a reduction in the patient's fear and anxiety, and thus improve the image quality and potentially reduce the quantity of sedative delivered to a patient, the conventional medical imaging room is modified with a theme, e.g., 60 and 660.
A “theme”, as used herein, represents a unifying idea or subject that is implemented in the medical imaging room, including thematic elements associated with and affixed to the medical imaging equipment. For example, some exemplary themes may include a rainforest and log ride, an outer space travel theme, a jungle theme, a sports theme, a child's birthday party, a doll house, a cartoon character theme, a pirate adventure, a safari theme, a circus theme, fantasy related themes, a museum theme, a farmyard theme, railroad theme and/or a fairytale theme, to name a few. Moreover, the theme may be related to a special character or medical imaging system mascot that is designed to be used in a medical image environment to reduce a patient's anxiety level. It should be realized that the above-described themes are exemplary and that the medical imaging room may be configured to represent other additional themes not discussed above and yet having the same function and possesses the required enablement.
All themes, those shown as 60 and 660 as well as those not shown and considered part of the present invention and comprises alternate embodiments thereof, are configured to reduce the level of patient anxiety and fear experienced by the patient being imaged by changing the conventional appearance and character of an imaging room to a theme unrelated to clinical and medical applications and procedures, thereby improving the image quality and clinical reliability, and reducing the need for sedation of the child.

Referring again to
Scenic design, as used herein represents an overall background “picture” that provides a physical appearance that represents the selected theme as produced in part by the applied painting designs and the foreground overlaid onto the painting scheme by the appliqué. In addition, only a portion of the walls 70 and 670 need to be painted as an appliqué overlays a portion to give a three dimensional appearance. For example, in the exemplary embodiment, the theme illustrated in
Scenic designs may be installed by substantially permanently by painting at least a portion of the medical imaging room and applying an appliqué. Optionally, a scenic design may be installed by utilizing a portable scenic device such as a picture or video display 92 and 692 (
In the exemplary embodiment, shown in
More specifically, in one embodiment, the tree appliqué 72 and/or the bird appliqué 76 may be fabricated as a sticker, or adhesive panel or label, that depicts a representation of a tree and a bird, respectively. In another embodiment, at least one of the tree or bird appliqués 72 and 76 may be fabricated as three-dimensional structure that is then affixed to a wall 70. Moreover, the tree appliqué 72 may be fabricated such that at least a portion of it extends at least partially outward from the wall.
In the exemplary embodiment, the appliqués are easily removable to facilitate either relocating the appliqués or removing them altogether to install another theme.
As discussed above, another one of the thematic elements may be embodied as a full-sized display device 92 and 692 (
At 202, a theme is designed to reduce the patient's anxiety, and thus reduce patient movement during the imaging process and improve the image quality as a result of the decreased movement. A theme, as used herein, represents a unifying idea or subject that is implemented in the medical imaging room to reduce patient anxiety.
At 204, at least one imaging room is modified by applying a plurality of elements on at least a portion of the imaging room and the medical imaging system, the elements collectively associated with the selected theme. For example, the walls of the imaging room may be painted to incorporate a scenic design associated with the selected theme. Appliques, props, and indicia may then be installed in the room.
At 206, a potential anxiety level of a patient is determined. In one embodiment, the patient's anxiety level may be determined based on a plurality of physiological parameters of the patient. For example, the anxiety level may be determined based on the patient's vital signs such as a patient's heart rate or breathing rate, or example. The current heart and/or breathing rate may then be compared to previous heart rate or breathing rate data acquired from the same patient. Patient's experiencing an increased heart or breathing rate is deemed to have an increased anxiety level. In another embodiment, the potential anxiety level of a patient is determined based on the patient's a priori knowledge of the medical imaging procedure. For example, one patient may have no knowledge of the imaging procedure and therefore have increased anxiety. Whereas another patient who has been previously imaged may have little or no anxiety. In one embodiment, the patient's anxiety is based on the patient's age. For example, a young patient may have no knowledge of the imaging procedure and therefore have increased anxiety. Whereas an older patient who has been previously imaged may have little or no anxiety.
At 208, an imaging room is selected based on the potential anxiety level. For example, assuming that the child is young or female and has relatively high anxiety level, an operator may determine that an imaging room having the rainforest theme, shown in
At 210 a medical imaging scan of the patient is performed in the selected imaging room. As discussed above, the medical scan may be performed using a computed tomography (CT) imaging system, a magnetic resonance imaging (MRI) system, a positron emission tomography (PET) imaging system, an ultrasound imaging system, an X-ray imaging system, and/or a single photon emission computed tomography (SPECT) imaging system.
At 302, a room in the medical imaging facility is selected. In the exemplary embodiment, the room is a medical imaging room that includes a medical imaging system, such as one of the medical imaging systems described herein.
At 304, a theme is designed to be installed in the selected room. As discussed above, the theme is designed based on a plurality of factors, some of the factors include a patient's age and a patient's gender. Other factors may include the quantity of patient's falling within a predetermined age group of gender. For example, assuming that eighty percent of the patients being imaged are relatively young, the theme may be designed having a more youthful appeal.
At 306, a second room in the medical imaging facility is selected. In the exemplary embodiment, the second room is a medical imaging room that includes a medical imaging system, such as one of the medical imaging systems described herein.
At 308, a second different theme is designed to be installed in the second room. As discussed above, the theme is designed based on a plurality of factors, some of the factors include a patient's age and a patient's gender. Other factors may include the quantity of patient's falling within a predetermined age group of gender. For example, assuming that twenty percent of the patients being imaged are adults, the second theme may be designed having a more adult appeal.
At 310, at least one of the first and second rooms is modified using one of the designed themes. More specifically, at least one of the first and second rooms is modified by applying a plurality of elements on at least a portion of the imaging room and the medical imaging system, the elements collectively associated with the selected theme. For example, the walls of the imaging room may be painted to incorporate a scenic design associated with the selected theme. Appliques, props, and indicia may then be installed in the room. In the exemplary embodiment, the first imaging room is modified to include a first theme and the second imaging room is modified to include a different second theme. During operation, each of the selected themes is configured to reduce an anxiety level of a patient being imaged in the room.
At 402, an age of a plurality of potential patients is determined.
At 404, a theme is designed based on the determined age. The theme is configured to reduce an anxiety level of a patient being image. More specifically, a theme is designed to reduce the patient's anxiety, and thus reduce patient movement during the imaging process and improve the image quality as a result of the decreased movement. A theme, as used herein, represents a unifying idea or subject that is implemented in the medical imaging room to reduce patient anxiety. For example, assuming that the patient is a child, a more youthful theme is designed. Whereas, another design may be directed to an adult. It should be realized that numerous themes may be designed and implemented in numerous respective imaging rooms. In this manner, a specific theme may be designed that facilitates reducing the anxiety level in young children and adults of both genders.
At 406, at least one imaging room is modified by applying a plurality of elements on at least a portion of the imaging room and the medical imaging system, the elements collectively associated with the selected theme. For example, the walls of the imaging room may be painted to incorporate a scenic design associated with the selected theme. Appliques, props, and indicia may then be installed in the room. Additionally, displays, sound systems, and audio systems may be employed as part of the overall theme. In the exemplary embodiment the installed theme includes a plurality of elements that collectively create the selected theme and forms a physical environment at least partially surrounding a patient being imaged.
At 408, a storyboard is utilized to explain the medical imaging system environment to a patient. Referring to
Described herein are a medical facility, a medical imaging system, and methods that are configured to reduce the patient's anxiety prior to the patient being imaged. A technical effect of the systems and methods described herein is reducing the amount of sedation to a patient and also increasing image quality. More specifically, as discussed above, the stark imaging environment combined with the patient's unfamiliarity with the imaging environment often increases the patient's anxiety, especially in children. As such, when utilizing a conventional imaging system, the patient's movement caused by the anxiety may extend the time required to perform the imaging, create a backlog at the imaging room, and/or decrease the quality of the images produced. To relax the patient, a doctor may increase the quantity of sedation given to the patient. While the sedation levels are within acceptable medical guidelines, the increased sedation may also result in an increase in the amount of time required for the patient to recover from sedation. As a result, the time required for a patient to being imaged in a conventional imaging system room is further increased.
The exemplary embodiments described herein reduce the time required to perform patient imaging, increase the quality of the images, and also reduces the amount of sedative given to a patient. Specifically, the imaging rooms described herein include themes that are specifically designed to reduce the anxiety level in patient's including younger patients. The imaging system room includes a theme that represents a place that is readily apparent to the child being imaged. The themes are implemented using a plurality of theme-related elements. The theme-related elements may include scenic designs on the walls and the imaging system itself Appliques, indicia, and props may also be placed in the imaging room to further enhance and define the selected theme. The themes described herein are readily apparent to a child being imaging and therefore immediately reduces the child's anxiety level before imaging. As a result, the patient may require a reduced amount of sedative than is used to image a child in a conventional imaging system, thereby decreasing the time required to perform imaging and improving image quality. Additionally, some patients, e.g. children, may not require anesthesia thus eliminating the need to inject the patient with a topical anesthetic which also leads to increased anxiety. Moreover, because of the patient has a reduced anxiety level, and thus moves less during the scan, the quantity of scans is reduced and the requirement to perform repeat scans is reduced. Additionally, the quantity of delays caused by waiting for a patient to recover from anesthesia is reduced, thus increasing the patient throughput through the imaging system room.
