Abstract
An approach to the design of a blood flow velocity measurement device in blood vessels is presented. The approach is based on a mathematical model of a multi-channel measuring system. The measurement of blood flow velocity is carried out in projections of blood flow velocity to the viewing directions of several receiving sensors. These directions are set by adjusting one common angle of inclination of the sensors during the measurement process. The synthesis of the measurement algorithm is carried out on the basis of a mathematical criterion. An analytical estimation of the measurement error is given. An example of error calculation is shown.
