VasoTracker 2: Open-source software and hardware for tracking blood vessel diameter and assessing vascular function.

ABSTRACT: VasoTracker 2 is a collection of open-source tools for blood vessel diameter measurement and vascular physiology research, featuring automated diameter tracking software and low-cost myography hardware components. This blood vessel analysis platform addresses the need for accessible alternatives to expensive commercial vascular imaging systems by providing comprehensive tools for studying vessel reactivity and endothelial function. The software enables multipoint diameter tracking in branched vessels using advanced edge detection algorithms, supporting brightfield microscopy, fluorescence imaging and ultrasound recordings. Automated pressure protocols enable standardized myogenic tone experiments, and both real-time and offline analysis of pre-recorded data are supported. The platform's ve
