Near-infrared second zone/one zone dual-mode fluorescence tomography system

Abstract

The invention belongs to the field of fluorescence imaging, and specifically relates to a near-infrared two-zone / one-zone dual-mode fluorescence tomographic imaging system, aiming at solving the problems of poor imaging quality and low positioning accuracy. An embodiment of a dual-mode fluorescent tomographic imaging system in the second near-infrared area / first area includes: an illumination module, an excitation module, an acquisition module in the second near-infrared area, an acquisition module in the first near-infrared area, a CT imaging module, and a central control module. The central control module , configured to reconstruct a three-dimensional tomographic image of the second near-infrared region and a three-dimensional tomographic image of the first near-infrared region based on the white light image, the fluorescence image of the second near-infrared region, the fluorescence image of the first region of near-infrared, and the fluorescence image. The beneficial effects of the present invention are: the reconstructed three-dimensional tumor signal has depth characteristics, which is closer to the real tumor distribution, and the reconstructed position is more accurate; the auxiliary image display unit can display the three-dimensional shape of the tumor intuitively, clearly and at any angle.

Description

technical field [0001] The invention belongs to the field of fluorescence imaging, and in particular relates to a near-infrared two-zone / one-zone dual-mode fluorescence tomographic imaging system. 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 includes two-dimensi...
