Development of the low-cost mammography equipment of high diagnostic performance independent of the breast type using the scatter ray.

对于使用散射辐射的乳房x线摄影，我进行了新技术的开发，以提高图像分辨率，提高Ca图像的检测灵敏度，减少曝光。(1)光学属性读取技术，采用人工智能技术。(2)信息提取空间滤波。(3)两步能量减法过程。(4)散射角减法。(5)空间频域减法。然而，这些都是不可能克服的问题，出现在每一个新技术，这些都没有付诸实际应用。

For mammography using the scattered radiation, I went the development of new technology to improve of image resolution, to improve of detectionsensitivity of Ca image, to reduce exposure. (1) Optical properties reading technique, by using artificial intelligence. (2) Information extraction spatial filter. (3) Two-step energy subtraction process. (4) Scattering angle subtraction method. (5) Spatial frequency domain subtraction. However, these are not possible to overcome the problem occurring in each of the new technology, these have not been put to practical use.
