ABSTRACT

This project presents the development of technology for monitoring of blood microcirculation status of human pancreas using the full-field speckle-correlation technique using rat animal model. The full-field speckle-correlometry is a noninvasive contactless technique that allows for imaging of capillary blood flow in a real time. This technique is based on the analysis of contrast of time-averaged speckle-modulated images. In this project, the main objectives are the following: to design technology for monitoring blood flow by Speckle Contrast Imaging; selection of optimal parameters of visualization of blood flow; also calibrate this technique by using the tissue phantom to obtain a calibration curve; monitoring changes of blood flow parameters by speckle-imaging in the development of pathologies. The calibration data will provide relationship between contrast of the speckle images and the velocity of modeling particles.
