Study on the calibration method of ultrasonic endoscope.

Ultrasonic endoscope integrates ultrasonic imaging and optical imaging systematically, which can observe the morphology of mucosal surface and obtain the histological information of each section. The ultrasonic endoscope is widely used in clinics, but there is still a lack of relevant research on the method of the measurement source of this instrument. Through the in-depth study of the working principle and measurement method of the instrument, a set of measurement traceability methods and calibration devices suitable for ultrasonic endoscope was developed, and the purpose of measurement calibration and measurement supervision was achieved.
