Background

In recent years, the incidence of breast cancer is on the rise, however, early diagnosis of breast cancer is still a difficult problem to be solved. Research shows that the early characteristics of the breast cancer are mainly reflected in the appearance of calcifications and tissue damage, the characteristics are found in time to carry out targeted treatment, and the breast cancer can be radically cured.

Early screening for breast cancer is currently achieved primarily by molybdenum-targeted X-ray imaging equipment. Such devices can only acquire two-dimensional images at a limited number of angles and the breast must be compressed in order to reduce the information overlap of the tissue within the breast and obtain a clearer image. However, the compression of the breast by this device not only causes pain to the patient, but the resulting image is of low quality, not sufficiently sharp and accurate. However, other devices such as breast tomographs, breast ultrasound, magnetic resonance, conventional CT devices, etc. do not solve the problems of image resolution and X-ray radiation dose well.

The prone type CT equipment special for the mammary gland can realize three-dimensional imaging of the breast, compression of the breast is avoided, but the prone type CT equipment has large occupied space and complex equipment structure, and greatly increases space cost and radiation protection cost of a hospital.
