Problems solved by technology

[0003] Most of the mammary gland phantoms in the prior art are compressed into a flat shape, which is not suitable for simulating the natural sagging state of the mammary glands under the special CT equipment for mammary glands, which is not conducive to the diagnosis of mammary glands

Abstract

The invention discloses a mammary model for a breast-specific CT device. The mammary model comprises a mammary model body, a detector placement hole and a photon counting detector. The detector placement hole is arranged inside the mammary model body, and the photon counting detector is located in the detector placement hole. A fiber silk simulant, a microcalcification simulant, a threshold contrast detail simulant and a simulated mammary tissue are further arranged in the mammary model body. The mammary model fully exhibits the X-ray attenuation characteristics during the simulation process,has obvious advantages in terms of dose efficiency and soft tissue characterization, has the advantages of wide application range and strong practicability, and is suitable for promotion and application.

Description

technical field [0001] The invention belongs to the technical field of medical imaging, and relates to a mammary gland phantom for CT equipment dedicated to mammary glands. Background technique [0002] Breast CT scanners are different from conventional CT scanners in that they only conduct tomographic scans for breast structures, avoiding unnecessary radiation doses to other parts of the body. The bed body of the equipment adopts a safe and comfortable prone structure, so that the subject's breasts sag and enter the CT scanning area, without squeezing the breasts, and the three-dimensional images of the breasts in the natural state can be reconstructed. Breast CT scanners have the advantages of short inspection time, low radiation dose, isotropic high resolution, and accurate stereotaxic positioning during imaging, which is of great significance for early detection, early diagnosis, and early treatment of breast cancer. [0003] Most of the mammary gland phantoms in the pr...
