This work is dedicated to development of the OCT system with angiography for everyday clinical use. Two major problems were solved during the development: compensation of specific tissue displacements, induced by contact scanning mode and physiological motion of patients (e.g. respiratory and cardiac motions) and on-line visualization of vessel net, to provide the feedback for system operator. The performance of the resulting OCT-based microangiography device with hand-held probe was evaluated by visualization of vessels nets of volunteers oral mucosa and skin on different locations (hands, face, abdomen etc.). Success-rate more than 90% was demonstrated during the experiments.
