ABSTRACT
<p><b>OBJECTIVE</b>Combined the optical principle with automatic control technology and computer real-time image detection technology to develop a non-contact system for noninvasive esophageal varices pressure measurement.</p><p><b>METHODS</b>The system included the adjustable air pump, laser device, image collection and analysis program. The feasibility and accuracy of the system were verified by in vitro experiments.</p><p><b>RESULTS</b>The bionic vascular pressure measured by this system had good correlation and repeatability with the actual pressure.</p><p><b>CONCLUSIONS</b>This system is accurate, feasible and has good application prospects.</p>
