High-temporal-resolution, full-field optical angiography based on short-time modulation depth for vascular occlusion tests

J Biomed Opt. 2016 Aug 1;21(8):86002. doi: 10.1117/1.JBO.21.8.086002.

Abstract

We developed high-temporal-resolution, full-field optical angiography for use in vascular occlusion tests (VOTs). In the proposed method, undersampled signals are acquired by a high-speed digital camera that separates the dynamic and static speckle signals. The two types of speckle signal are used to calculate the short-time modulation depth (STMD) of each of the camera pixels. STMD is then used to realize high-temporal-resolution, full-field optical angiography. Phantom and biological experiments conducted and demonstrated the feasibility of using our proposed method to perform VOTs and to study the reaction kinetics in microfluidic systems.
