Description

technical field [0001] The invention belongs to the technical field of biomedical engineering, and in particular relates to a low-dose digital breast tomography method, device and breast imaging equipment. Background technique [0002] DBT (Digital Breast Tomosynthesis, digital breast tomosynthesis) is a new type of breast imaging equipment, which is listed as a recommended method in the breast cancer screening guidelines of many countries. However, DBT uses an X-ray rotary scanning method similar to CT (computed tomography), which will cause ionizing radiation damage to the female body. According to breast cancer screening guidelines, women over the age of 40 should receive an examination once a year, and the accumulated ionizing radiation damage over the years is serious. [0003] Therefore, reducing the radiation dose of DBT scanning and reducing the harm of ionizing radiation to patients will become an urgent technical problem to be solved while maintaining the image qu...
