Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The present invention combines the OPT imaging model under the weak scattering situation with the OPT fluorescence reconstruction algorithm, utilizes the method based on the normalized Born ratio to correct the OPT fluorescence signal attenuation, adopts Monte Carlo technology to simulate the scattering component in the measurement data, and obtains from the detection data It is removed in , and an iterative framework that effectively combines attenuation correction and scattering component estimation is studied to achieve quantitative 3D reconstruction of OPT fluorescent dye concentration.
