Near-infrared two-zone fluorescence tomography system

Abstract

The invention provides a near-infrared two-region fluorescence tomography system. The system comprises a structure information acquisition module which emits an X-ray beam, and acquires a spatial structure image of a sample, a light source module which emits white light and laser, and respectively obtains a white light image and a fluorescence image after the sample is illuminated, an optical information collecting module which acquires the white light image and the fluorescent image and a central control module which controls the structure information acquisition module, the light source module and the optical information collecting module; the spatial structural image, the white light image and the fluorescent image are read, and a near-infrared two-region fluorescence tomography image of the sample is obtained according to the spatial structure image, the white light image and the fluorescence image.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a near-infrared two-zone fluorescence tomographic imaging system. Background technique [0002] With the development of medical imaging technology, optical molecular imaging has become a new-generation imaging mode widely used in life science basic research and clinical diagnosis. Optical tomography combined with traditional imaging techniques such as X-ray CT, magnetic resonance imaging, etc., can obtain structural information and molecular information of lesions, especially near-infrared fluorescence molecular tomography, by injecting targeted fluorescent probes and using laser excitation The probe collects the emitted light, which can realize non-invasive and non-invasive lesion detection, and has the characteristics of high sensitivity and high specificity. [0003] However, due to the large absorption effect and scattering effect in the biological tissue, the near-infrared imaging ha...

AI Technical Summary

Problems solved by technology

[0003] However, due to the large absorption effect and scattering effect in the biological tissue, the near-infrared imaging has a weak penetrating ability, and it is difficult to image the target at a deep position. In addition, due to the absorption of biological tissue, the distribution of optical signals Hard to get close to the true distribution

In summary, near-infrared imaging in the first region has been difficult to meet the clinical needs
