Functional-molecular-structural imaging system and method

Abstract

The invention discloses a low-cost large-field functional-molecular-structural imaging system and method aiming at medical isotope. The system comprises a functional-molecular-structural imaging coaxial detector, a data processing device and a computer device, wherein the functional-molecular-structural imaging coaxial detector is used for scanning a physical imaging object to obtain the functional and molecular imaging image information and structural imaging image information of the physical imaging object and outputting the information to the data processing device; the data processing device is used for receiving and storing the functional and molecular image information and decomposing the structural information, carrying out fusion calculation on the functional-structural images, drawing a multi-modality fused section image, and transmitting the image to the computer device for displaying; and the computer device is used for realizing image reconstruction and displaying the functional-molecular-structural multi-modality fused section image. According to the invention, a charge-coupled device and spiral CT (computerized tomography) are adopted for detecting effective information at coaxial aperture position, thus as compared with PET (positron emission tomography) / CT, SPECT (single photon emission computed tomography) / CT and other bi-modality imaging devices, the imaging axial-direction field is enlarged, the whole body imaging time is shortened, and the isotope imaging cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a low-cost and large-field functional-molecular-structural imaging system and method for medical isotopes. Background technique [0002] Information fusion of function-molecule-structure is the clinical demand and development trend of nuclear medicine imaging technology. In recent years, the fusion technology of functional molecular imaging and structural imaging has been greatly developed and applied. For example, Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT) and Computed Tomography (CT), Magnetic Resonance Imaging (MRI) ) fusion, PET / CT, SPECT / CT, PET / MRI and other multimodal images have appeared in clinical applications. [0003] In 2008, scholars at the University of Freiburg (Nat.Clin.Pract.Oncol.2008; 5:160-170.) pointed out through statistics that the annual number of PET / CT scans in the United States increased by nearly 7...

AI Technical Summary

Problems solved by technology

With the existing technology and technical level, it is difficult to increase the area of ​​the crystal array unit; a PET / SPECT instrument often needs multiple crystal array units; the gap between the crystal units cannot detect gamma particles, forming a physical imaging blind spot

PET / SPECT has high requirements on crystal array fabrication and layout process, high cost, and the axial scanning field of view is seriously restricted
