Quality control of mammography

The density difference of breast tissue itself is very small, and many lesions show tiny calcification. Therefore, mammography is the most difficult examination method in traditional radiological diagnosis, and the requirements on machinery and technology are also the most stringent. X-ray photography is a kind of invasive examination, and breast is a highly sensitive tissue to radiation. In order to minimize the risk of radiation damage and ensure the safety and effectiveness of screening practice, scientific image quality control procedures must be seriously implemented. Obtaining high-quality images is the premise of making correct diagnosis, and strict quality control is the guarantee of obtaining images.

The objectives of quality control mainly include two points:

1 to ensure that high-quality images that can provide rich diagnostic information can be obtained when appropriate imaging technology is adopted;

2, under the premise of meeting the requirements of diagnostic information, ensure the lowest radiation dose. A qualified mammography team needs the close cooperation of radiologists, projection technicians and maintenance physicists, and the staff should be relatively fixed to ensure the quality.
