Near infrared region-two and region-one bimodal fluorescence tomographic system and method

Abstract

The invention belongs to the field of fluorescence imaging, particularly relates to a near infrared region-two and region-one bimodal fluorescence tomographic imaging system and method, and aims to solve the problems of poor imaging quality and low positioning accuracy. The near infrared region-two and region-one bimodal fluorescence tomographic imaging system comprises an illumination module, anexcitation module, a near infrared region-two acquisition module, a near infrared region-one acquisition module, a CT imaging module and a central control module, wherein the central control module isconfigured to reconstruct a near infrared region-two three-dimensional tomographic image and a near infrared region-one three-dimensional tomographic image based on a white light image, a near infrared region-two fluorescence image, a near-infrared region-one fluorescence image and a fluorescence image. The system has the beneficial effects that: the reconstructed tumor signals in a three-dimensional space have depth characteristics, are closer to real tumor distribution, and the reconstructed position is more accurate in reconstruction position; the system is assisted by an image display unit which can intuitively and clearly display the three-dimensional shape of the tumor at any angle.

Description

technical field [0001] The invention belongs to the field of fluorescence imaging, and in particular relates to a near-infrared second region / first region dual-mode fluorescence tomographic imaging system and method. Background technique [0002] Cancer is one of the major diseases threatening human health with a high mortality rate. "Early detection and early treatment" is an important measure to reduce the mortality rate of cancer patients and improve their quality of life. However, traditional tumor detection methods such as CT (Computed Tomography, computerized tomography), MRI (Magnetic Resonance Imaging, Magnetic Resonance Imaging) and ultrasound cannot accurately detect early micro-tumors. With the development of medical imaging technology, optical molecular imaging technology is expected to become a new generation of imaging mode for early and high-precision detection of cancer, which is of great clinical value. [0003] Optical molecular imaging technology mainly ...
