Image registration device and method for multi-model imaging system

Abstract

The invention discloses an image registration device and method for a multi-model imaging system. The image registration device comprises a positioning base, a closed cavity, test tubes and a seal cover. The closed cavity is fixed in one side wall of the positioning base, each test tube is a thin tube with an open end, developing agents are injected into the test tubes, the test tubes are placed in the closed cavity, and the axes of the test tubes are parallel with the an examination shaft. The seal cover is used for sealing the closed cavity, and when FMT registration is performed, the inside of the closed cavity is filled with media; the positioning base is made of nontransparent material; the closed cavity and the test tubes are made of transparent material. Based on rigid body registration, parameters are relatively simple, the registration accuracy is high, registration can be performed on a two-model, or three-model or four-model combination in four-model imaging devices flexibly and accurately, and particularly the accuracy of FMT and other model image registration is improved.

Description

technical field [0001] The invention relates to the field of biomedical imaging, in particular to a registration device and a registration method for image registration of a multimodal imaging system. Background technique [0002] Medical imaging technology has played an important role in realizing the non-invasive, high-sensitivity, and high-resolution detection of the essence of life in a living state. However, due to the complexity of living organisms, any single imaging modality cannot fully dissect biological processes. Therefore, multimodal medical imaging technology has been developed rapidly once it was proposed. It combines the respective advantages of multiple imaging modalities and can provide prior information to each other, which can provide imaging results more comprehensively, accurately and reliably. For example, computed tomography CT can accurately provide anatomical information of organisms. Positron emission computed tomography PET, single photon emiss...

Problems solved by technology

In 2012, the research team led by Ren Qiushi of Peking University realized the CT / PET / SPECT / FMT four-modal imaging system for the first time, but there is no suitable device and method suitable for four-modal registration.

In addition, as an emerging imaging device, FMT has not yet proposed a device and method for accurate registration of FMT and other modalities
