Description

Technical Field

[0001] The utility model relates to the technical field of CT examination auxiliary instruments, and particularly relates to a human body fixing device for breast CT examination. Background Technique

[0002] When performing a CT examination on the breast, the patient can adopt a supine position or a prone position. The advantage of the supine position is that the patient is more comfortable, but due to the action of gravity, the breast sags and the full picture and pathological features of the breast cannot be accurately displayed; adopting the prone position can make the breast hang naturally, but the patient needs to lie on the detection guide rail and support the upper body with the arms and keep a certain angle without moving. This position requires some physical strength and will feel tired after a long time. Moreover, some patients will move during the examination, resulting in unclear examination images, failing to meet the quality of the examination images, and requiring re-scanning, increasing the examination time and radiation dose. For this reason, we propose a human body fixing device for breast CT examination. Content of the Utility Model
