Embodiment Construction

[0019] In order to make the technical means of the present invention and the technical effects it can achieve more clearly and more perfectly disclosed, the following examples are provided hereby for detailed description as follows:

[0020] Prior to this, most of the existing scan positioning operation procedures are as follows: the doctor enters the operation room, first lets the patient lie on the diagnosis bed, then turns on the internal and external laser lights on the gantrykeypad, and moves the diagnosis through the gantrykepad according to the patient information and scanning protocol Bed, and then press the positioning button on the gantrykeypad to complete the positioning.

[0021] The positioning operation at the system level is actually the conversion of two coordinate systems (CT diagnosis bed code coordinate system, doctor scan coordinate system). CT diagnostic bed code coordinate system, this coordinate system is fixed, for example, the scannable CT diagnostic b...

Abstract

The invention provides a non-contact CT (Computed Tomography) scanning positioning method, which relates to the technical field of CT scanning positioning and comprises the following steps of: writingall horizontal position information of a CT diagnostic bed into a scanning protocol, and converting a CT diagnostic bed code coordinate system and a doctor scanning coordinate system to obtain converted coordinate information; then writing the converted coordinate information into the scanning protocol; selecting the scanning protocol, obtaining current conversion coordinate information in the protocol, and transmitting the current conversion coordinate information to a CT motion subsystem; allowing the CT motion subsystem to perform data conversion according to the current conversion coordinate information and the current diagnostic bed coordinate information input by a doctor to obtain the current diagnostic bed actual coordinate information; and allowing the CT motion subsystem to automatically finish the mobile positioning of the CT diagnostic bed according to the actual coordinate information of a diagnostic bed and in combination with the selected scanning protocol and the scanning part information. According to the scanning positioning method, the doctor needs to enter a shielding room, the doctor can be prevented from contacting and infecting a patient, and the infection probability of the doctor is reduced.

Description

technical field [0001] The invention relates to a CT scanning positioning method, in particular to a non-contact CT scanning positioning method. Background technique [0002] At present, the main transmission routes of the new coronavirus are respiratory droplet transmission and contact transmission, and aerosol and feces-oral transmission routes need to be further clarified. The transmission of the new coronavirus has various routes and is highly contagious. Among them, medical staff have a relatively high infection rate as close contacts. Thousands of medical staff have been diagnosed with new coronavirus pneumonia. [0003] In "Radiological Diagnosis of Novel Coronavirus Pneumonia: Expert Recommendations of Chinese Medical Association Radiology Branch (First Edition)", it is mentioned about CT examination: "For the radiological examination of novel coronavirus infection, volume CT scan is the first choice." , CT scan is the preferred radiological examination for new coro...
