Special adjustable posture pad for cone beam breast CT

Abstract

The invention discloses an adjustable posture pad special for cone beam breast CT. The adjustable posture pad is an air cushion body. The air cushion body comprises a chest position pad and a leg position pad, wherein the chest position pad is positioned on the same side as the leg position pad; the chest position pad is provided with a hollow mammary gland examination hole, the size of the mammary gland examination hole is matched with the size of a breast on one side of a human body, the mammary gland examination hole is positioned at the middle part of the chest position pad; the chest of asubject clings to the edge of the examination hole, the breast passes through the mammary gland examination hole and naturally droops into a cone beam mammary gland CT scanning cavity; and air volumeand temperature of air introduced into the chest position pad and the leg position pad are adjustable. According to the chest position pad disclosed by the invention, the body position is adjusted when a subject is subjected to breast examination scanning, and the one-sided chest position pad can be adjusted laterally when the one-sided breast is examined, so that the one-sided chest position ofthe subject is fixed and is suitable for examination scanning; and meanwhile, the posture pad solves the problem that the breast on the other side is compressed and feels uncomfortable when the subject is subjected to breast CT examination. The temperature of the air introduced into the posture pad can be adjusted, so that the emotion of the subject can be relieved, the movement in the inspectionprocess can be prevented, and the generation of artifacts can be prevented.

Description

technical field [0001] The invention relates to an auxiliary equipment technology for mammary gland CT examination, in particular to an adjustable body position pad specially used for cone-beam mammary gland CT. Background technique [0002] At present, the conventional methods for the examination of breast diseases include breast color Doppler ultrasound, mammography, breast CT, and enhanced mammography. When ordinary CT is used for breast CT examination, fan-shaped X-rays (high penetration) are used to precess vertically along the vertical axis from the middle of the patient's clavicle to the epigastric region, and a circular scan is performed on the cross-section of the human body to produce a circular scan that includes the spine and ribs. , breast profile of the chest to form a three-dimensional image. Cone-beam breast CT scanners, also known as cone-beam breast CT scanners, have appeared on the market. The principle is to use cone-shaped X-beams to continuously scan t...

Problems solved by technology

like figure 2 As shown, the specific structure of the cone-beam breast CT scanner is as follows: the upper surface of the cone-beam breast CT scanner B is an examination bed B2, and the middle part of the examination bed is concave, and an examination opening B2 is opened, and the examination bed is equipped with a 360° horizontal Rotating scanning frame, X-ray tube and X-ray detector are installed on the scanning frame; since there is only one inspection opening of the cone beam breast CT scanner, every time a breast scan is performed, one side of the human body needs to be close to the chest In the middle of the examination opening, the examinee’s cheek is pressed against the surface, and the breast scan is performed, while the other breast is squeezed to a certain extent, which makes the examination experience not good; The bed is cold, which can easily lead to mood swings in the patient. A slight movement during the inspection process will cause motion artifacts in the output image, which will affect the detection results.
