Abstract

The invention discloses a bimodal system and method integrating photoacoustic imaging and fluorescence imaging. In the invention, the complementarity between photoacoustic imaging and fluorescence imaging on the imaging theory is used, and through a common scanning light path system, photoacoustic imaging and fluorescence imaging are effectively integrated into a whole. The device for realizing the method of the invention comprises an photoacoustic imaging subsystem, a fluorescence imaging subsystem and a computer, wherein the photoacoustic imaging subsystem and the fluorescence imaging subsystem are integrated through the scanning light path system; the computer is respectively connected with the photoacoustic imaging subsystem, the fluorescence imaging subsystem and the scanning light path system; and the computer not only controls the scanning mode of the scanning light path system, but also processes the data of the photoacoustic imaging subsystem and the fluorescence imaging subsystem, combines the photoacoustic information and fluorescence information, and reconstructs photoacoustic and fluorescence bimodal images. The method of the invention has accurate positioning and high resolution, and the imaging system has lower cost and easy popularization.

Description

technical field [0001] The invention relates to a multimodal imaging method, in particular to an imaging system and imaging method integrating photoacoustic and fluorescent dual modes. Background technique [0002] The progress of medical imaging physics and technology and the invention and development of medical imaging equipment have greatly promoted the diagnosis and treatment of human diseases under non-invasive or less invasive conditions, thus greatly prolonging human life and providing support for the development of human body functions under non-invasive conditions. Research creates the conditions. Although traditional medical imaging technology has its own characteristics in the diagnosis and auxiliary treatment of diseases, there are still many shortcomings in a single imaging method. Magnetic resonance imaging (MRI) has a high resolution and can obtain anatomical and physiological information at the same time. However, the weakness of MRI is not only low sensiti...
