Description

Technical Field

[0001] The present invention relates to the technical field of CT image examination, and in particular to an auxiliary device for CT image examination. Background Art

[0002] Computed Tomography (CT) is a common medical imaging technique that uses X-rays and computer technology to generate detailed cross-sectional images of the body's internal structures. Unlike traditional X-rays, CT scans can provide clearer three-dimensional images, allowing doctors to diagnose and evaluate diseases more accurately.

[0003] When using CT imaging to examine the patient's head, it is often necessary to use special auxiliary devices to stabilize the patient's head to ensure that the patient's head can remain stable during the examination, thereby obtaining clear, accurate and diagnostically valuable head CT imaging results, providing a reliable basis for subsequent medical diagnosis and treatment plan formulation.

[0004] In the process of realizing the present invention, the inventors found that the prior art has the following problems: 1. When some existing common auxiliary devices are used to fix the patient's head, it is usually necessary to move and adjust the two clamping structures separately to clamp and fix the patient's head. The adjustment method is time-consuming and labor-intensive, which may affect the inspection efficiency; 2. In some existing common auxiliary devices, the soft material is generally fixed on the device. After long-term use, various types of dirt will accumulate on the surface of the soft material. Since the soft material is fixed on the device, it is not convenient to disassemble and clean the soft material. Summary of the invention
