- Abstract
- We demonstrate an agent-free multi-structural peripheral angiography technique based on the volumetric photoacoustic (PA) and ultrasound (US) images. The volumetric images are obtained by stacking B-mode PA/US images along the elevational direction using a motorized scanner. Three structural features such as skin, bone, and vasculature are extracted from the volumetric US image and combined with the PA microvasculature image to provide a multi-structural vascular image of the foot. For quantitative PA imaging, we have tested the reliability of the PA images. The method can be used to provide a comprehensive anatomic and functional analysis of the extremity. ? COPYRIGHT SPIE.
