Abstract
The present disclosure includes support devices configured to be prevent breast deformation during an MRI imaging procedure. One embodiment of a support device comprises a foam insert shaped and sized to rest between a patient's breasts, generally upon the patient's sternum. The support device has a surface configured to engage an imaging modality component (i.e., coil of MRI machine) and prevent and/or minimize contact between the portion of the MRI coil and the pair of breasts when the support device is placed on the surface of the patient, which, in turn, reduces or eliminates any deformation of the breasts upon application of force from the MRI coil in a direction towards the breasts during an MRI imaging procedure. Another embodiment of a support device comprises a rigid cover including an interior cavity having sufficient volume to accommodate and surround each breast, wherein the cover is coupled to a telescoping stand resting upon the MRI table and configured to move between a variety of heights to accommodate different-sized patients. The cover is sufficiently rigid so as to shield the breasts from compression forces and thereby prevent deformation during an MRI imaging procedure.

[0020] For a thorough understanding of the present disclosure, reference should be made to the following detailed description, including the appended claims, in connection with the above-described drawings. Although the present disclosure is described in connection with exemplary embodiments, the disclosure is not intended to be limited to the specific forms set forth herein. It is understood that various omissions and substitutions of equivalents are contemplated as circumstances may suggest or render expedient.
DETAILED DESCRIPTION
[0021] By way of overview, the present disclosure is generally directed to support devices configured to reduce or prevent breast deformation by resisting compression forces applied to the breasts during a supine MRI imaging procedure. By preventing or reducing breast deformation, particularly during a supine MRI imaging procedure, any tissue abnormality within the breast tissue may generally remain in its natural resting location, particularly when the patient is lying in a supine position, rather than move as a result of the compression force. Thus, the support device of the present disclosure allows for a more accurate MRI image to be taken. More specifically, the support device will prevent a tissue abnormality from shifting from its natural resting position when the patient is lying in the supine position. Thus, the resulting MRI image will provide an accurate location of the tissue abnormality within the breast tissue, upon which a physician can rely when performing a subsequent diagnostic and/or therapeutic procedure with the patient lying in the supine position.
[0022]
[0023] As shown, support device 100 is generally in the form of an insert having a body including a central portion 101 configured to rest between the breasts upon the patient's sternum, an upper portion 102 configured to rest above the breasts (i.e., closer to the patient's collar bone), and a lower portion 106 configured to rest below the breasts (i.e., closer to the patient's navel area). Each of the upper and lower portions 102, 106 generally flare out, such that the support device 100 comprises an x-shape or an I-beam shape. For example, the upper portion 102 includes a first pair of extensions 104a, 104b, and the lower portion 106 similarly includes a second pair of extensions 108a, 108b. The central portion 101 is contoured so as to generally accommodate a breast on either side. In particular, the central portion 101 includes opposing sides 110a, 110b, which may include an arcuate shape so as to accommodate the inner portion of each respective breast 14a, 14b. The first and second pairs of extensions 104a, 104b and 108a, 108b of the upper and lower portions 102, 106 have a corresponding arcuate shape as the opposing sides 110a, 110b of the central portion 101. In particular, the arcuate shape generally extends out from the central portion 101 to both the upper and lower portions 102, 106. Accordingly, the first pair of extensions 104a, 104b of the upper portion 102 may accommodate a top portion of each respective breast 14a, 14b, while the second pair of extensions 108a, 108b of the lower portion 106 may accommodate and effectively cradle a bottom portion of each respective breast 14a, 14b.
[0024] The support device 100 is shaped and sized so as to provide a surface upon which a portion of a diagnostic imaging machine (e.g., a breast coil for an MRI machine) may rest, thereby reducing or completely eliminating contact between the breast coil of the MRI machine and each breast, which, in turn, reduces or completely eliminates compression and deformation of each breast during the imaging procedure. For example, when the support device 100 is positioned upon the patient's chest (i.e., the central portion 101 is resting between each breast), at least one of the central portion 101, upper portion 102, and lower portion 106 may be elevated from the patient's chest to a sufficient height to thereby provide a surface upon which the breast coil of an MRI machine will rest. As such, the support device 100 is configured to receive any application of a downward/posterior compression force applied thereto from dressings or supports associated with an anterior receive coil of the MRI machine, while allowing for each breast to be maintained in a relatively stationary position during the MRI procedure.
[0025] The support device 100 may be sufficiently rigid so as to provide adequate support to resist deformation upon a compression force applied thereto, such that each breast is able to maintain its stationary position and resist deformation. The support device 100 may be composed of a sufficiently rigid polymer material, for example, which may generally be in solid foam form. However, it should be noted that the support device 100 can include any material that is sufficiently rigid and configured to provide adequate support. Furthermore, the support device 100 may be composed of a material rated for use in medical imaging procedures.
[0026] The support device 100 may generally include a single size, but, depending on the size of the breasts, multiple support devices may be stacked upon one another to a desired height to accommodate larger-sized breasts so as to maintain a top surface of the support device to a sufficient height to engage a breast coil for an MRI machine and reduce or prevent contact between the breast coil and each breast. For example, smaller-sized breasts may generally require one support device (or an assembly of less support devices), as compared to larger-sized breasts, which may generally require more than one support device, including an assembly of multiple stacked support devices. For example as shown in
[0027]
[0028] The cover 204 may be disposable. For example, a new cover 204 may be used (i.e., slid onto the spine member 202) each time an imaging procedure is performed for any given patient. Once the procedure has been performed, an operator may then simply remove and discard the cover 204 and replace with a new cover 204 for the next patient. Accordingly, the support device 200 can be used for a plurality of patients over the course of a plurality of procedures, in that only the cover 204 need be replaced, while the same spine member 202 can be used from patient to patient and procedure to procedure. The spine member 202 may be sufficiently rigid so as to provide internal support for the support device 200 (i.e., resistant deformation upon a compression force applied thereto, such that each breast is able to maintain its stationary position and resist deformation). For example, the spine member 202 may be composed of a molded elastomer or polymer material. The cover 204 may be composed of a material configured to provide a cushioning effect, such as a foam material for example. Alternatively, the cover 204 may be composed of a polymer material, generally in the form of a film for sliding over the spine member 202. The cover 204 may also have an exterior surface that is shaped, sized and/or contoured in such a manner so as to generally match the surface of a patient's chest, thereby providing a form fit.
[0029] Similar to the support device 100 previously described herein, the support device 200 may generally include a single size, but, depending on the size of the breasts, multiple support devices may be stacked upon one another to a desired height to accommodate larger-sized breasts so as to maintain a top surface of the support device to a sufficient height to engage a breast coil for an MRI machine and reduce or prevent contact between the breast coil and each breast. For example, smaller-sized breasts may generally require one support device (or an assembly of less support devices), as compared to larger-sized breasts, which may generally require more than one support device, including an assembly of multiple stacked support devices.

[0031] The cover 302 is coupled to a telescoping stand configured to rest upon an MRI table and configured to move between a variety of heights to accommodate different-sized patients and/or different-sized breasts. The telescoping stand generally includes a base portion 308, which may generally be in the form of a pair of feet, for example, sufficiently spaced apart and configured to rest on either side of a patient 12 lying in a supine position on the MRI table 10. The telescoping stand further includes a pair of arms 306 coupled to the corresponding pair of bases 308 with feet 309 and coupled to the cover 302.
[0032] The pair of arms 306 are configured to move relative to the corresponding pair of feet 309 between a plurality of temporarily fixed positions, as indicated by arrow 310, via an interlocking mechanism (not shown). Accordingly, movement of the arms 306 between the plurality of temporarily fixed positions with the pair of feet 309 results in movement of the cover 302 between a plurality of heights relative to the patient, thereby providing adjustability to accommodate a variety of different-sized patients. The interlocking mechanism between the pair of feet and pair of arms may include a quick release lever and teeth locking joints, for example. Furthermore, there may be sufficient spacing between each vertical position so as to allow the arms to slightly move so as to accommodate subtle chest rising and falling as the patient breathes. Additionally, or alternatively, elastic members may be included between the arms and feet the thereby allow subtle movement there between to account for patient breathing (i.e., the cover 302 to rise and fall in correspondence with rise and fall of the patient's chest).
[0033] The cover 302 may be provided in a limited number of sizes (i.e., four overall sizes) to accommodate most breast sizes. As previously described, the cover 302 may be sufficiently rigid so as to shield the breasts from compression forces and thereby prevent or reduce breast deformation during an MRI imaging procedure. The cover 302 may be composed of a sufficiently rigid polymer material, for example. However, it should be noted that the cover 302 can include any medical grade material that is sufficiently rigid and configured to provide adequate support. Furthermore, the cover 302 may be composed of a material rated for use in medical imaging procedures.
[0034] In some embodiments, the support device 300 may be configured to allow for width adjustments, in addition to height adjustments, so as to better accommodate different shapes and sizes of patients. For example,\ as shown in
[0035]
[0036] The support devices of the present disclosure are advantageous in that they are each configured to reduce or prevent breast deformation by resisting compression forces applied to the breasts during an MRI imaging procedure. By preventing or reducing breast deformation, particularly during an MRI imaging procedure, any tissue abnormality within the breast tissue may generally remain in its natural resting location, particularly when the patient is lying in a supine position, rather than move as a result of the compression force. Thus, the support devices of the present disclosure allow for a more accurate MRI image to be taken. More specifically, the support devices will prevent a tissue abnormality from shifting from its natural resting position when the patient is lying in the supine position. Thus, the resulting MRI image will provide an accurate location of the tissue abnormality within the breast tissue, upon which a physician can rely when performing a subsequent diagnostic and/or therapeutic procedure with the patient lying in the supine position.
