PET-CT (Positron Emission Tomography-Computed Tomography) arrangement system capable of reducing stroke of scanning table and disassembling and assembling method of PET-CT arrangement system

Abstract

The invention relates to a PET-CT (Positron Emission Tomography-Computed Tomography) arrangement system capable of reducing the stroke of a scanning table and a disassembling and assembling method of the PET-CT arrangement system. The PET-CT arrangement system comprises a PET machine, a CT machine, a sickbed, two groups of main supporting units, two groups of guide rail units, two groups of sickbed supporting units and two groups of sickbed synchronous moving units, wherein the PET machine is provided with a PET rack; the PET machine is arranged at the front side of the CT machine; the sickbed is arranged in front of the PET machine; the main supporting units are respectively arranged at two sides of the bottom part of the PET machine and are used for supporting, aligning and adjusting the PET machine; the guide rail units are respectively and detachably arranged at the front sides of the main supporting units; the PET rack can slide from the main supporting units to the guide rail units; the sickbed supporting units are used for supporting and locating the sickbed; the sickbed synchronous moving units are arranged on the sickbed supporting units and can move on the sickbed supporting units; each sickbed synchronous moving unit comprises a flexible connecting device; the flexible connecting devices are detachably connected with the PET rack. According to the PET-CT arrangement system disclosed by the invention, the separation of the PET machine and the CT machine is simple and easy, and the time for adjusting a scanning axis after the separated PET machine is reset is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a PET-CT arrangement system capable of reducing the stroke of a scanning bed and a disassembly method thereof. Background technique [0002] Existing multi-image systems generally include a CT machine, a PET machine, and a hospital bed, and the CT machine and the PET machine are often installed side by side and close together. During the daily maintenance and repair of CT machines and PET machines, it is necessary to move the CT frame or PET frame, and reset the CT frame or PET frame after the maintenance is completed. Because the coaxiality of CT machine, PET machine and hospital bed is very high when they are installed, if the CT frame or PET frame is directly moved during maintenance, the adjustment of the coaxiality of CT machine, PET machine and hospital bed will be It takes a lot of time and is inefficient. Moreover, moving the CT frame or the PET ...

AI Technical Summary

Problems solved by technology

During scanning, in order to obtain PET imaging, the movement distance of the hospital bed is large, the stability is reduced, and the position of the patient on the hospital bed is prone to shift, which will eventually adversely affect the imaging quality of PET-CT scanning

Moreover, the CT bulb in the CT machine is a high-heating component. If the CT machine is too close to the patient, it will bring hidden dangers to the patient's safety.
