Estimation of the blood volume in pneumatically controlled ventricular assist device by vision sensor and image processing technique

The paper presents research of measuring the blood chamber volume of a ventricular assist device (VAD) using vision sensor and image processing technique. During research, the modified method was used of measuring the distance to an object based on one image obtained from a motionless camera with a fixed-focus lens. The paper presents the VAD model, measurement station as well as results of experiments.
