[0002] CT scans are one of the most advanced modern medical imaging techniques. CT scans generally include plain scans, enhanced CT scans, and cisternography. CT uses an X-ray beam to scan a layer of a certain thickness within a part of the human body. The X-rays transmitted through the layer are received by a detector, converted into visible light, and then converted photoelectrically into electrical signals. These signals are then converted to digital form by an analog-to-digital converter and fed into a computer for processing.

[0003] A typical CT medical vehicle typically houses the CT equipment in a carriage with a hydraulically driven lift platform mounted at the rear. When a CT scan is needed on a patient at a disaster area or major accident site, the vehicle first drives to the patient's location and lowers the lift platform. The operator then dismounts and lifts the patient onto the lift platform, which then lifts the patient and operator to the carriage. The operator then places the patient into the CT equipment for examination.

[0004] At present, there is no comprehensive operation efficiency monitoring system for the lifting platform of CT medical vehicle, and the safe operation of the lifting platform cannot be effectively monitored. Therefore, an operation efficiency monitoring system suitable for the lifting platform of CT medical vehicle is proposed. Summary of the Invention
