Abstract:Objective To obtain more accurate blood flow values, a fiber optic probe suitable for near-infrared diffuse correlation
tomography (DCT) technology was designed and manufactured based on 3D printing. Methods Solidworks was used for 3D
modeling of the fiber optic probe. According to the design model, photosensitive resin material was used to complete the 3D printing
of the optical fiber probe. The effectiveness of the 3D printed flat optical probe was verified in simulation experiment and human
experiments. Results In the simulation experiment, the blood flow imaging probe designed by using 3D printing technology can
clearly image and accurately locate the solid anomaly. In the human experiment, it can accurately and stably obtain the blood of
head tissue of 30 cases of subjects, and the flow changes and imaging is performed. Conclusion The optical fiber probe made by
3D printing technology is suitable for near-infrared DCT and can accurately obtain the changes of tissue blood flow. The probe is
expected to be used for clinical diagnosis and treatment evaluation of a variety of brain diseases.
