Abstract

The invention provides a system for imaging in tissues of living organisms. The system comprises an ultrasonic unit, quantum dots, a collection unit, an optical convergence unit and a detection unit.The ultrasonic unit excites the quantum dots which are arranged in the tissues of the living organisms in advance and converts optical signals which are generated due to sonoluminesence into infraredsignals, then the collected infrared signals are converged and transmitted to the optical detection unit to be detected, the infrared signals are detected and recorded, and thus three-dimensional imaging is completed. An ultrasonic probe excites the tissues of the living organism to generate the optical signals which are generated due to sonoluminesence and converts the optical signals into the infrared signals, and three-dimensional imaging in the tissues is completed by collecting infrared light. The system can conduct imaging in the tissues of the living organisms, guarantee the measurementdepth, and meanwhile can achieve higher resolution.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a system for imaging in biological tissue. Background technique [0002] The interior of living tissue cannot be directly imaged due to its opaque and heterogeneous nature. Diffuse Optical Tomography, also known as Diffuse Optical Tomography or OpticalDiffusion Tomography (DOT / ODT), can be developed through the development of highly sensitive near-infrared photon detection instruments and image reconstruction technology based on photon transport models in biological tissues. Invert the three-dimensional distribution of optical characteristic parameters inside the tissue from the time, space and spectral distribution measurement information of the surface diffused light under multi-point excitation, and correlate it with the physiological state of the tissue, with X-ray, ultrasound and magnetic resonance Compared with other conventional imaging methods, it has obvious advantages in...
