Imaging method and positioning device of X-ray imaging equipment

Abstract

The invention provides an imaging method of X-ray imaging equipment. The X-ray imaging equipment comprises an X-ray bulb tube and a detector, and an imaging view exists between the X-ray bulb tube and the detector. The method is characterized by comprising the steps that an object to be detected is arranged in the imaging view; the object to be detected is imaged at at least two different positions, and images of the object to be detected are obtained; interested areas in the images are acquired; the space positions of the interested areas are calculated according to the interested areas in the images; the imaging position of the X-ray imaging equipment is adjusted according to the position relation between the space positions of the interested areas and the imaging view. According to the imaging position determining method, the position of an ROI in space can be acquired, the imaging position of the X-ray imaging equipment in any direction can be calculated according to the space position of the ROI, and it is guaranteed that the ROI is located within the imaging view range.

Description

technical field [0001] The invention relates to the field of medical imaging equipment, in particular to a method and device for determining an imaging position of an X-ray imaging equipment. Background technique [0002] All current designs of C-arm machines, whether it is isocentric rotation or non-isocentric rotation, when the C-arm rotates, images at different positions will deviate to varying degrees. figure 1 is a schematic diagram of the rotation of the C-arm machine with isocentric rotation; figure 1 As shown, the isocenter rotation means that when the X-ray emitted by the X-ray emitting tube 20 is received by the detector 10, the center line of the beam formed between the two passes through the isocenter (Isocenter), and the process of the rotation of the C-arm machine The centerline of the beam described in , always passes through the isocenter. If the region of interest (hereinafter referred to as ROI) is not in the isocenter when the isocenter of the C-arm mach...
