One-equipment room transmission PET/CT/MR image collection, registering and imaging system and method

Abstract

The invention relates to a forming and imaging method of a magnetic resonance image collection, registering and imaging system, wherein the system comprises a PET machine, an MR machine, a CT machine and an image processing work station, and particularly, the system also comprises a movable scanning bed and a magnetic insulation door which can be simultaneously applied to the PEC machine, the MR machine and the CT machine. The imaging method mainly comprises the following steps: moving the movable scanning bed to respectively carry out scanning along the MR machine, the PET machine and the CT machine without changing the body position of a detected object to collect three groups (MR, PET and CT) of images of the same part; carrying out three-dimensional reconstruction on the three groups of images by the image processing work station; carrying out the first registering and fusion by using the PET / MR and the PET / CT; and using image batch processing programs for simultaneously carrying out the second registering and fusion on the PET images and the MR fracture layer collection images on the same layer in the same position. The imaging quality is obviously improved, at the same time, the radiant quantity of a scanning system is obviously reduced, and the injury on the detected object is reduced.

Description

Technical field: [0001] The invention belongs to a medical image imaging technology, in particular to a composition and an imaging method of a magnetic resonance image acquisition, registration and imaging system. Background technique: [0002] PET / MR is the development direction of medical molecular imaging at present. There are usually two technical means used. One is a heterogeneous system. This system has many disadvantages: PET and MR belong to different departments, and factors such as objects to be examined are relatively variable. Another PET / MR system developed in Europe in 2008, but there are still many problems in popularization and application: such as inserting PET in the middle to make MR into a large ring, how to ensure the quality of MR images? The imaging principle of MR is completely different from that of PET. How to use MR to correct the attenuation of PET? In order to overcome the interference of the magnetic field on the PET, a photodiode detector is u...

[0002] PET / MR is the development direction of medical molecular imaging at present. There are usually two technical means used. One is a heterogeneous system. This system has many disadvantages: PET and MR belong to different departments, and factors such as objects to be examined are relatively variable. Another PET / MR system developed in Europe in 2008, but there are still many problems in popularization and application: such as inserting PET in the middle to make MR into a large ring, how to ensure the quality of MR images? The imaging principle of MR is completely different from that of PET. How to use MR to correct the attenuation of PET? In order to overcome the interference of the magnetic field on PET, a photodiode detector is used, which greatly increases the manufacturing cost
