Abstract
A compression device for a mammography x-ray apparatus comprises the breast in a manner that is as comfortable as possible for the patient. For this purpose, a compression device has a frame that two-dimensionally stretches an elastic membrane and is designed so that the breast of a patient that is to be compressed by the compression device is compressed solely by the elastic membrane.
Claims10
A compression device for a mammography apparatus, comprising:
- a frame mounted for movement relative to a stationary breast;
- an elastic membrane spanning said frame, said frame being configured to two-dimensionally stretch said elastic membrane and said frame having a shape and dimensions configured to cause compression of the breast solely by said elastic membrane.
A mammography apparatus comprising:
- an x-ray source that emits an x-ray beam;
- a support plate configured to support a breast thereon within said x-ray beam;
- a radiation detector disposed to detect radiation in said x-ray beam after penetrating the breast on the support plate;
- and
- a compression device configured to compress the breast against said support plate, said compression device comprising a frame that is mounted for movement relative to said support plate, a membrane spanning said frame, and said frame having a shape and dimensions to two-dimensionally stretch said elastic membrane to compress the breast on the support plate solely by the elastic membrane.
