Abstract

The invention discloses a coordinate registration motif of a multi-mode detection system, and belongs to the technical field of medical imaging. The coordinate registration motif comprises a supporting plate and N supporting columns. One ends of the N supporting columns are fixed to the supporting plate, the other ends of the N supporting columns are provided with N containers, and the other end of one of the supporting columns is correspondingly provided with one container; any four of the N containers are not in the same plane, and projections of the N containers in the vertical direction of the multi-mode detection system are non-overlapped; and mixed liquor of an X-ray developing agent and a tracer agent is stored in each of the N containers, and N is an integer which is greater than or equal to 4. The stability of the coordinate registration motif is improved, and the using cost is saved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a coordinate registration phantom of a multi-modal detection system. Background technique [0002] In a multi-modal detection system, the images of the same target object detected by two different detectors are usually coupled to realize the analysis of the target object. For example, in a PET-CT (Positron Emission Tomography-Computed Tomography, Positron Emission Tomography-Computed Tomography) detection system, the PET image of the lesion in the human body detected by the PET detector and the image of the human organ tissue detected by the CT detector are Coupled with CT images, in order to locate the location of the lesion. In order to facilitate the coupling of PET images and CT images, before the PET image is detected by the PET detector and the CT image is detected by the CT detector, the FOV (Field-of-View) coordinate system of the PET detector and the CT The FOV...
