Description

Automatic localization of blood vessels is important to many clinical procedures. In this contribution we have improved our automatic technique, presented last year at MICCAI 2014, by increasing the accuracy of the algorithm and extending the range of applications to include ultrasound imaging. Our new contribution incorporates a mathematical model of radial distension (expansion and contraction of vessel-like structures) to highlight structures that pulsate like a blood vessel, while ignoring tissues that merely translate at pulsatile frequencies.
