Problems solved by technology

Scanning users mainly rely on subjective judgment and scanning experience to judge the scanning area of ​​the patient, there is a lot of uncertainty, and the work intensity of scanning users will also affect their judgment on the scanning area
In addition, the scanning of positioning images also consumes the power stored in the mobile CT system, which affects the number of scans

Embodiment Construction

[0055] The present invention proposes an intelligent positioning system for mobile CT, which mainly guides the user to move the examination bed to align with the scanning frame through auxiliary vision, or guides the scanning frame to align with the examination bed to complete the positioning before scanning Function. The specific implementation includes three types: projection mode, vision mode and fully automatic mode.

[0056] 1. Projection mode

[0057] Such as image 3 As shown, in this mode, a projector is set on the scanning gantry to project the scanning range and auxiliary positioning lines of the gantry to guide the user to align the position of the examination table and the patient. Define the coordinate system of the projector, take the moving direction of the examination bed as the x-axis direction, and the direction perpendicular to the x-axis on the plane where the examination bed is located is the y-axis direction. The scanning frame is perpendicular to the ...

Abstract

The invention discloses a mobile CT intelligent scanning positioning system, a positioning method and a storage medium, the system comprises an image acquisition module, a distance detection module, a geometric calibration module, an intelligent analysis module, a motion control module and a projection module, the geometric calibration module is used for calculating a coordinate transformation relationship among the projection module, the image acquisition module and a mobile CT machine; the intelligent analysis module is used for carrying out intelligent analysis on the image acquired by the image acquisition module and acquiring a human body template part area and human body center line information; the projection module is used for projecting the contour of the to-be-scanned area and an auxiliary positioning line on the sickbed according to the information of the to-be-scanned area. The scanning area is positioned through auxiliary vision, an operator is guided to move the examination bed to be aligned with the scanning rack, or the scanning rack is guided to be aligned with the examination bed to complete positioning, a target scanning area can be quickly scanned to obtain a CT image without scanning a positioning image, and time and power consumption for scanning the positioning image are saved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a mobile CT intelligent scanning positioning system, a positioning method and a storage medium. Background technique [0002] The mobile CT system can play an important role in specific occasions such as operating rooms, simple shielded rooms, ICUs and other medical places with imperfect venues. If the patient is connected to multiple life support devices at the same time, he cannot lie on the hospital bed and move like in a conventional CT examination. Unlike the traditional CT system, the mobile CT system has lower requirements on the site. The mobile CT system does not have a precise motion examination table, and the mobile CT system has lower requirements on the site. It performs CT scans on stationary patients by moving the gantry. For a mobile CT system, the examination table is usually an operating table, and it is easy to move the examination table to meet the ne...
