Description

{Breast Cancer Diagnostic Apparatus}

The present invention relates to a device for diagnosing breast cancer which photographs mammograms of a subject to diagnose general diseases occurring in breast including breast cancer.

1 and 2 are perspective views showing a general breast cancer diagnostic apparatus.

Generally, as shown in Figs. 1 and 2, the breast cancer diagnostic apparatus includes an X-ray generating device 13 and an X-ray detecting device 15 opposed to each other, and an X- And a paddle (17) arranged between the line detecting device (15).

Here, the X-ray generating device 13 and the X-ray detecting device 15 are arranged vertically, and the paddle 17 is movable up and down, and approaches the X-ray detecting device 15 at the time of descent. The X-ray generating device 13, the detecting device 15 and the paddle 17 are rotatably mounted on the apparatus main body 11 with a horizontal axis as a center. The X-ray generating device 13, And the detecting device 15 are arranged so as to be inclined at a constant angular rotation around the horizontal axis.

Such breast imaging by the breast cancer diagnostic apparatus is performed by moving the paddle 17 while placing one breast of the examinee on the pedestal of the X-ray detecting apparatus 15 and pressing the breast of the examinee by the paddle 17 Ray generator 13 is operated to irradiate X-rays toward the pressed breast. At this time, the X-ray detecting device 15 detects X-rays from the X-ray generating device 13 transmitted through the breast on the pedestal and generates X-ray projection data. Of course, the acquired X-ray projection data can be outputted as an image by the display.

Since breast cancer actually develops in the glandular tissues, the main purpose of breast imaging using such a breast cancer diagnostic device is to obtain a contrast and resolution image that can be reproduced. In addition, since most of the breast cancer occurs in the central and lateral part of the breast with a high mammary gland distribution, it is necessary to choose the posture and the technique to accurately express this part during mammography.
