    摘要: According to an aspect there is provided a method for automatic maintenance of a dialysis system. The dialysis system includes a plurality of filter sections where each filter section includes a blood flow channel, a dialysate flow channel, and a membrane separating the blood flow channel from the dialysate flow channel and having a plurality of pores through which substances are exchanged between a blood flow in the blood flow channel and a dialysate flow in the dialysate flow channel. The method includes determining, for each filter section of the plurality of filter sections, whether a maintenance criterion is fulfilled. The method also includes triggering a maintenance event for a filter section of the plurality of filter sections for which the maintenance criterion is fulfilled. The method also includes executing the maintenance event and optionally administering a thrombolytic agent to the blood flow channel of the filter section.

    摘要: At least one embodiment relates to an autofocus method for determining a focal plane for at least one object. The method includes reconstructing a holographic image of the at least one object such as to provide a reconstructed image at a plurality of different focal depths. The reconstructed image includes a real component and an imaginary component. The method also include performing a first edge detection on the real component for at least two depths of the plurality of different focal depths and a second edge detection on the imaginary component for the at least two depths. Further, the method includes obtaining a first measure of clarity for each of the at least two depths based on a first measure of statistical dispersion with respect to the first edge detection and a second measure of clarity.
