Three-dimensional structure functional imaging system

Abstract

The invention provides a three-dimensional structure functional imaging system which comprises a frequency domain optical coherence tomography subsystem, a fluorescence imaging and spectral analysis subsystem and a front-end scanning structure subsystem. According to the frequency domain optical coherence tomography subsystem, low coherence light is used as a light source, and the light source is input into a coupler after passing through a polarization controller, split to a reference arm and a sample arm and then returned back to the coupler to form a coherent light field. The fluorescence imaging and spectral analysis subsystem can be provided with multiple selectable light sources, a light way is adjusted at the light machine part, and a light source with the preset power is obtained and coupled to a sample light way of the frequency domain optical coherence tomography subsystem. The front-end scanning structure subsystem is used for coupling the light sources of the fluorescence imaging and spectral analysis subsystem and the sample light of the frequency domain optical coherence tomography subsystem into the same light way, a two-dimensional scanning galvanometer is used for scanning emergent light to form a dot matrix image of a two-dimensional structure, and therefore a three-dimensional image comprising surface fluorescence signals and a structure fault is obtained. The three-dimensional structure functional imaging system has the advantages of being high in resolution ratio, low in cost, good in stability and high in reliability and achieving noninvasive imaging.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a three-dimensional structural functional imaging system. Background technique [0002] Central nervous system lesions have become a major killer that threatens human life, and have attracted people's attention because of their high mortality and disability rates. At present, surgery is the first choice for the radical treatment of central nervous system lesions and tumors, and high-resolution structural and functional images will provide precise guidance for surgery. Due to the shortcomings of the current imaging analysis, detection and diagnosis methods such as low resolution, radioactivity, and single structure-function imaging, it is very important to develop non-radiation, high-resolution, integrated structure-function imaging equipment, and the structure-function Imaging is an important means to solve the above problems. [0003] At present, the commonly used intr...

Problems solved by technology

[0005] At present, functional magnetic resonance imaging (fMRI) is the mainstream technology of functional imaging, but as mentioned above, its imaging resolution is low, and it is difficult to determine accurate lesion identification
