Problems solved by technology

The traditional three-dimensional spatial distribution reconstruction algorithm of in vivo (In vivo) CW-FMT needs to use dual-mode or multi-modal imaging, which increases the cost and technical complexity of the imaging system, and introduces more noise interference. Imager comfort is also reduced

Abstract

The invention relates to an image processing method and an image processing system. The image processing method includes acquiring multi-frame fluorescent two-dimensional image data according to a to-be-imaged object; taking the fluorescent two-dimensional image data as input, and establishing a first equation according to a diffusion equation theory, wherein the first equation is used for describing a relationship between real target distribution of fluorescence molecular probes of the to-be-imaged object and the fluorescent two-dimensional image data; solving the first equation according to a preset solving method so as to obtain final reconstruction target distribution of the fluorescence molecular probes of the to-be-imaged object, wherein the final reconstruction target distribution is used for describing a three-dimensional reconstruction result of tomography of the fluorescence molecular probes of the to-be-imaged object. The image processing method provides auxiliary prior information without other imaging modality, so that cost and technical complexity of an imaging system are greatly lowered.

Description

technical field [0001] The present invention relates to the technical field of fluorescence molecular tomography, and more specifically relates to an image processing method and system. Background technique [0002] Continuous Wave Fluorescence Molecular Tomography (CW-FMT) can realize in vivo non-invasive monitoring of the three-dimensional spatial distribution of fluorescent molecular probes in vivo, and observe physiological and pathological activities at the cellular and molecular levels process, and has the characteristics of no ionizing radiation, low cost and high safety, and has been widely used in medical research. [0003] The reconstruction of the three-dimensional spatial distribution of fluorescent molecular probes in the detection body in CW-FMT is the core of the algorithm of the whole technology. It is necessary to reconstruct the three-dimensional spatial distribution of fluorescent molecular probes in the detection body through the collected multi-angle flu...
