Description

Upright breast dedicated CT imaging equipment

technical field

The utility model relates to the technical field of X-ray imaging, in particular to an upright breast dedicated CT imaging device.

Background technique

In recent years, the incidence of breast cancer is on the rise, but the early diagnosis of breast cancer is still an urgent problem to be solved. Studies have shown that the early characteristics of breast cancer are mainly reflected in the appearance of calcifications and tissue damage. If these characteristics are detected in time and targeted treatment, breast cancer can be cured.

At present, the early screening of breast cancer is mainly realized by mammography X-ray imaging equipment. This kind of equipment can only collect two-dimensional images of limited angles. In order to reduce the overlapping of information in the breast tissue and obtain a clearer image, the breast must be compressed. However, the compression of the breast by the device not only causes pain to the patient, but also the image quality obtained is low, not clear and accurate enough. And other equipment such as breast tomography machine, breast ultrasound, magnetic resonance and traditional CT equipment can not solve the problem of image resolution and X-ray radiation dose very well.

The prone-type breast CT equipment can realize three-dimensional imaging of the breast and avoid breast compression, but it occupies a large space and has a complex equipment structure, which greatly increases the space cost and radiation protection cost of the hospital.
