Problems solved by technology

However, because OCT uses near-infrared light as a detection method, its frequency is much higher than that of ultrasonic waves. Therefore, the resolution of OCT images (a few microns to a dozen microns) is more than 10 times that of ultrasonic images. The disadvantage is that the imaging depth of OCT is only ( One to two millimeters), so the imaging depth of the two is very different
In recent years, although universities and research institutions have been developing dual-mode imaging probes that combine ultrasound and OCT, due to technical difficulties, complex processes, complex assembly, and differences in imaging depth, the stability and reliability of the work are still improving. Therefore, there is no such dual-mode probe available in clinical practice at present.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a dual-mode probe combined with ultrasonic imaging and optical coherence tomography. Background technique [0002] At present, ultrasonic imaging technology and OCT (optical coherence tomography) technology are relatively mature in the field of medical endoscopic imaging, and are widely used in clinical disease diagnosis and surgical assistance. In endoscopic imaging technology, the probe is the core component of the endoscopic imaging system, which directly determines the image quality. Ultrasound has better penetrability to biological tissues, and can reach tens of millimeters to several centimeters, and the imaging depth is much greater than that of OCT. However, because OCT uses near-infrared light as a detection method, its frequency is much higher than that of ultrasonic waves. Therefore, the resolution of OCT images (a few microns to a dozen microns) is more than ...
