Modeling of Blood Perfusion in Dependence of Scanning Angle from LDPI Data

The paper deals with issue of the modelling and analysis of a scanning angle influence on the blood perfusion, and consequent proposal for their elimination. The first essential step of analysis is angle stabilization. In this step, we utilize special artificial arm allowing for a measuring angle adjustment in the scale of two axes. The modelling allows for simulation of perfusion units (PU) in the form of the quadratic model, which is consequently recalculated in the form of the linear expression. The second part of the analysis deals with the PU modelling in the dependence of the distance. In our analysis, we particularly use a segment of middle finger and forearm. In the last part, we propose theoretical conception of the curvature correction influence. This theoretical proposal leads to the relationship between measured and real PU
