Breast positioning compression device and mammography system

Abstract

The invention discloses a mammary gland positioning compression device, which is installed on a mammography system, comprising: an upper compression plate for compressing the breast from top to bottom; on the support arm of the compressor and slide up and down under the support of the support arm of the compressor; the lower compression plate, used to support the mammary gland, is arranged on the support arm of the compressor and up and down under the support of the support arm of the compressor sliding, and lateral translation; the lower compression plate is arranged below the upper compression plate and above the image receiver; when positioned, the upper compression plate compresses the mammary gland from top to bottom, and the lower compression plate is Elevate the mammary glands from the bottom up. The invention also provides a mammography system. Use the lower compression plate to lift up the mammary glands, and can move laterally to fully pull as many mammary glands into the imaging area. It can also fully adapt to the shape of the mammary glands to achieve a positioning effect that cannot be achieved by applying force from the upper side without increasing or reducing the impact. When the examiner feels uncomfortable due to the tension of the skin, the part of the mammary gland covered in the image area is further increased, so that the detection effect of the mammary gland is better.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to a breast positioning compression device and a mammography system. Background technique [0002] In the mammography system, mammary gland compression is an important operation link. Standardized and reasonable positioning and compression can make the breast tissue cover the X-ray image area as much as possible, reducing the missed diagnosis caused by lesions outside the image area; compression helps to fix the breast and prevent the image from blurring due to the movement of the breast during exposure . A good positioning compression design should also consider ergonomics to minimize the discomfort caused by breast compression. [0003] Conventional methods of oppression ( figure 1 As shown), the mammary glands are placed on the housing of the image receiver, and the compression plate moves from top to bottom to compress the mammary glands. This way of applyi...

Problems solved by technology

This way of applying force from one side does not fully consider the condition of the lower part of the mammary gland. In many cases, even if it is very hard, it will only tighten the skin above the mammary gland. cause severe pain
