Development of an Experimental Setup for Intraoperative Angiography System

The article is devoted to technological and program features of developing and creating an experimental setup for intraoperative imaging. Clinical problem of the necessity of vessel imaging has been established. Current state of intraoperative vessel imaging has been analyzed. Structure of the setup has been determined. The requirements for parts of the setup have been formulated. Usage of infrared radiation for vessel imaging has been justified. A chicken breast tissue as an ex-vivo model has been chosen. Usage of the chlorophyll as a new liquid for blood substitution has been experimentally justified. Strobing as an approach to the vessel imaging has been used. A MATLAB-based model for quality evaluation of functions of the setup has been developed. A research for verification of functionality of the setup has been undertaken. Peak signal-to-noise ratio as the main criteria for the setup verification has been used. A prediction of further usage of the results obtained has been made.
