摘要： The present invention relates to the field of digital pathology and in particular to whole slide scanners. Autofocus imaging can be performed by sampling a first number of pixels of a primary image sensor which is a time delay integration (TDI) sensor, and sampling a second number of pixels of an autofocus image sensor, wherein the second number is between one quarter and three quarters of the first number. Thus, continuous autofocus for rapid light scanning may be provided based on an additional image sensor that is tilted with respect to the optical axis.

摘要： A scanning microscope includes a stage for holding a sample, a scan mechanism, a probing system for probing a region of the sample, a position sensor, and a controller. The scan mechanism is configured to translate the stage between at least two axial positions. The probing system includes an optical element and a photosensor having a readout region, where the readout region extends in a direction which is transverse to an ideal orientation of the stage. The position sensor is configured to measure a transverse position of the stage and/or of an orientation of the stage. The controller is configured to adapt the probing system as a function of the measured transverse position and/or the measured orientation.

摘要： An autofocus imaging system for a microscope system includes a tilted autofocus image sensor that images an oblique cross-section of a slide. The autofocus imaging system focuses multiple sequential overlapping images, which have been taken by the tilted autofocus image sensor, by making a comparison of the multiple sequential overlapping images. An axial position of a tissue layer on the slide can be determined from a polar error signal resulting from this comparison.

摘要： A method of analyzing a sample fluid containing organic microobjects is proposed. The method comprises the steps of: up-concentrating (S1) the microobjects by removing, in a total time T1, a volume V1 of the sample fluid from the upconcentrate sample microobjects; immersing (S2) the microobjects in a transfer fluid, or leaving the microobjects in a remaining portion of the sample fluid, the remaining portion of the sample fluid then providing the transfer fluid; filtering (S3), in a total time T3, a volume V3 of the transfer fluid by a filter, thereby accumulating the microobjects on the filter; and generating (S4) an image of the microobjects accumulated on the filter; wherein the throughput V1/T1 of the step of up-concentrating (S1) is greater than the throughput V1/T1, of the step of filtering (S3). The filter may be a second filter, and the step of up-concentrating (S1) may involve: filtering the sample fluid by a first filter, thereby accumulating the microobjects on the first filter. An apparatus or system for analyzing a sample fluid containing organic microobjects is also disclosed.
