Description

Technical Field

[0001] The utility model relates to the technical field of CT scanning equipment, in particular to a lifting platform used for CT scanning. Background Art

[0002] CT is the abbreviation of Computed Tomography, which is a scanning method that uses computer technology to reconstruct the tomographic image of the object to be measured to obtain a three-dimensional tomographic image. This scanning method is to penetrate the object to be measured through rays of a single axial plane. According to the different absorption and transmittance of the rays by each part of the object to be measured, the computer collects the transmitted rays and reconstructs the image through three-dimensional. CT scanning equipment generally needs to be used with a lifting platform. The lifting platform generally includes a manual slide and an automatic slide. The manual slide requires medical staff to manually push the examinee into the CT scanning equipment for scanning, while the automatic slide does not require manual operation by medical staff to push the examinee into the CT scanning equipment for scanning, which is more efficient and convenient to use. However, when an emergency or failure occurs, the automatic slide stops in the CT scanner, making it difficult for the examiner to get off the platform. Therefore, it is necessary to design a lifting platform for CT scanning that can automatically switch to a manual slide in the event of a failure or power failure in an emergency.
