AI Technical Summary
Current methods for computing microcirculatory resistance values and transit times for vessels are prone to errors due to imprecise definitions of distal positions, difficulties in accurately determining vessel lengths, and variations in vessel lengths between subjects.
A system that normalizes microcirculatory resistance values by dividing them by a transit length, providing a more reliable metric less sensitive to the location of the distal position. Additionally, a method to correct transit times by using reference fluid velocity data and cardiac cycle data to account for variations in blood velocity throughout the cardiac cycle.
The normalization of microcirculatory resistance values and correction of transit times lead to more accurate and reliable vessel parameter measurements, reducing inter- and intra-user variations and improving clinical diagnostics.
