## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image receptor support device and particularly those used for mammogram systems.
2. Background
Mammograms have become routine diagnostic requiring the placement of a woman's breasts over an image receptor. X-rays pass through the breast tissue to create an image for examination. An image receptor support device, sometimes referred to as a Bucky plate, provides the support and patient interface surface for conducting this procedure. An image receptor support device typically comprises a substantially x-ray transparent material that allows the x-rays to pass through to the image receptor. An image receptor may be a physical sheet or a digital receptor. AN image receptor may be configured to slide into an image support device. Many women put off or completely refrain from scheduling mammograms as they find the procedure to be very uncomfortable. Image receptor support devices are not configured with a woman's comfort in mind. They are typically a rectangular plate having relatively sharp edges. Women must press hard against the support device for proper positioning of the breast, and this rectangular shaped image receptor support sometimes causes bruising along the patient's rib cage and/or abdomen. In addition, the sharp edges of the rectangular shaped image receptor support can be very uncomfortable as it presses into the patients skin. Furthermore, the image receptor support device is typically cold to the touch making the procedure more uncomfortable. Patients confined to a wheelchair often find it particularly difficult to position themselves properly against an image receptor support device.
SUMMARY OF THE INVENTION
The invention is directed to an image receptor support device that is configured with a patient engagement side having a concave central portion, a rounded left portion and rounded right portion. The image receptor support device, of the present invention, allows a woman to more easily and comfortably position their body to achieve proper placement of their breast over an image receptor. The curved central portion enables more complete placement of the breast over the image receptor portion of the machine without causing excess pressure against the patient. In some embodiments, an image receptor support device comprises a top surface and a bottom surface, wherein the bottom surface, along the patient engagement side, is recessed from the top surface. This recessed bottom surface further reduces unnecessary pressure against the patient. An image receptor support device or detachable interface to an image receptor support device may allow better positioning of a particular body part over and image receptor and therefore result in a better diagnosis of the patient's condition.
The concave central portion of the patient engagement side may comprise a contour having a radius of any suitable dimension including, but not limited to a radius of about 10 cm or more, about 12 cm or more, about 20 cm or more, about 25 cm or more, about 38 cm or more and any range between and including the radius values provided. The concave center portion may be centrally located between the left and right sides of the image receptor support device or offset from a central location. The concave central portion may have any suitable concave shape including bowl shaped and irregular shaped, for example. An irregular shaped patient engagement side may further improve positioning of the breast over the image receptor while being comfortable to the patient.
The rounded left and rounded right portions comprise a contour having a radius of any suitable dimension including, but not limited, about 5 cm or more, about 15 cm or more, about 20 cm or more, about 25 cm or more, about 38 cm or more and any range between and including the radius values provided. The rounded left and rounded right portions may extend to the sides of the image receptor support device or extend beyond the sides, wherein the corners of the image receptor support device along the patient engagement side are rounded.
An image receptor support device, as described herein, comprises a substantially x-ray transparent material and in some cases a specific imaging portion consisting essentially of an x-ray transparent material.
