Current limitations

In recent years, Particle Image Velocimetry (PIV) has demonstrated to possess the appropriate potential to enhance the quality of the design and associated reliability of biomedical devices for human implantation. Nevertheless, the high benefits that would be induced by a standardised application of PIV technology in the context of biomedical industry and medical practise are not fully exploited, due to some major limitations of the current state of the art:

inadequate temporal and spatial resolutions of a PIV system required for biomedical applications, which limits the efficiency of the PIV especially in terms of inadequate capability to detect small scale vortices, large spatial and temporal velocity gradients as well as localised stagnation,which are known to be present in such a flow field

inability to provide results in case of complex shape devices where shaded areas are not easily illuminated by the light sheet

the unavailability of efficient cost-effective techniques to minimise the overall processing time of the experimental investigation, but without loosing accuracy and results interpretation capacity
