Abstract

The invention provides a coordinate registration mold, a multimode imaging system and an image registration method thereof, and belongs to the field of medical devices. The coordinate registration mold includes a bracket and a plurality of mold bodies. The bracket includes a first supporting rod, a second supporting rod intersecting with the first supporting rod and at least three third supportingrods whose extension direction intersects with the extension direction of the first supporting rod and intersects with the extension direction of the second supporting rod, the second supporting rodis connected with the third supporting rods, and at least two third supporting rods are arranged along the second supporting rod in a separation mode. At least two mold bodies of the molds are arranged on the first supporting rod in a separation mode, at least three mold bodies are arranged on at least three third supporting rods, and at least two mold bodies are arranged in the extension direction of the third supporting rods in a separation mode. The mold bodies include cavities for containing radioactive materials and through holes communicating with the cavities, and the through holes areformed in the top wall of the body. The coordinate registration mold is simple in structure, convenient and flexible to install, large in scanning range and beneficial to accurate image registration.

Description

technical field [0001] The present disclosure relates to the field of medical devices, in particular to a coordinate registration phantom, a multimodal imaging system and an image registration method thereof. Background technique [0002] The multimodal imaging system includes a plurality of different detectors, which combine the respective advantages of multiple imaging modes, which is beneficial to accurately determine the location of the patient's lesion. For example, PET-CT (Positron Emission Tomography-Computed Tomography, Positron Emission Tomography-X-ray Computed Tomography) equipment includes PET detectors and CT detectors. However, due to the different installation methods of PET detectors and CT detectors, it is easy to cause different imaging positions of the same detection site in the imaging field of view, which is not conducive to determining the location of the lesion. The coordinate registration phantom can determine the deviation between the scanning field...
