A convenient method for testing and calibrating surface perfusion sensors has been developed. A phantom tissue model is used to simulate the nondirectional blood flow of tissue perfusion. A computational fluid dynamics (CFD) model was constructed in Fluent® to design the phantom tissue and validate the experimental results. The phantom perfusion system was used with a perfusion sensor based on clearance of thermal energy. A heat flux gage measures the heat flux response of tissue when a thermal event (convective cooling) is applied. The blood perfusion and contact resistance are estimated by a parameter estimation code. From the experimental and analytical results, it was concluded that the probe displayed good measurement repeatability and sensitivity. The experimental perfusion measurements in the tissue were in good agreement with those of the CFD models and demonstrated the value of the phantom tissue system.

AbstractThe aim of this study was to investigate the usefulness of new software Pixel Flux (PXFX) for clinical evaluation of tissue perfusion in the field of reproduction in dogs. The experiment was performed on six adult Beagle dogs. Different organs and tissues of the animals were examined with the MyLab25 Gold ultrasound system. Blood flow in the ovary, testicle, prostate, the ramification of the penile artery, and the network of blood vessels of the pampiniform plexus were examined with the use of colour coded Doppler technique, and obtained data was evaluated with the PXFX software. The more objective digital evaluation of data obtained with colour Doppler sonography through the application of dynamic tissue perfusion measurements provides new opportunities for diagnosis, as well as continuous monitoring of the function of the examined tissues and organs. The use of PXFX software is strongly indicated as a tool in small animal practice as an additional method for evaluation of tissue perfusion, especially in the cases when other methods like pulsed wave Doppler techniques are difficult to be performed
