Abstract

The heart assist pump of a pneumatic type has a pneumatic chamber and a blood chamber separated by a flaccid membrane. During operation, the membrane changes its shape. Its reconstruction is possible using a camera with a wide-angle lens and the DFD method for visual distance measurement. The measurement is carried out simultaneously at characteristic points indicated by passive markers placed on a membrane surface. Due to their limited number, to obtain a proper numerical description of a membrane shape, spatial interpolation in the actual dimensions is necessary. In the paper, the method of interpolation and the results of reconstruction tests based on 3D printed models were presented.
