    摘要: A method of analyzing a plurality of histology slides is provided, wherein possible artefacts are detected at an early stage. This is achieved by including a preliminary imaging and image analysis step in the process flow; the step being executed preferably before any diagnostic assessment e.g. image analysis or manual reading is performed by a pathologist or a lab technician. Accordingly, the histology slides reaching the expert for image analysis are of a higher quality, since the slides are ideally free of artefacts. The method thus saves valuable time for the pathologist, since only artefact-free slides will be subject to a detailed analysis. Furthermore, the method minimizes the risk of misinterpretations leading to potentially false diagnoses. A deep learning model, is also disclosed, which is capable of automatically determining whether histopathological images are suitable for diagnostic and/or research assessment. A training of the deep learning model is also disclosed.

    摘要: A processor for lifetime-based unmixing in fluorescence microscopy is configured to acquire an image having a plurality of pixels, each pixel providing information on photon count and photon arrival times, generate a phasor plot that is a vector space representation of the image, partition the image into image segments, evaluate the image segments according to total photon counts of the corresponding subsets of pixels, and execute a lifetime classification by selecting an image segment having a largest total photon count, determining a region of interest in the image encompassing the image segment, determining a phasor subset in the phasor plot corresponding to the region of interest, and generating a lifetime class including a set of image segments corresponding to the phasor subset. A plurality of lifetime classes is generated by iteratively executing the lifetime classification. The processor is configured to perform lifetime-based unmixing using the life-time classes.

    摘要: An Enterobius vermicularis detection system is provided comprising a sample substrate, a sample disposed upon the sample substrate, and a personal computing device comprising an imaging device for acquiring one or more digital images of the sample substrate. The personal computing device may operate a digital interface allowing the acquired one or more digital images to be uploaded to one or more analysis computation servers. The one or more analysis computation servers may execute an analysis process upon the uploaded one or more digital images allowing determination of a presence of one or more Enterobius vermicularis eggs within the sample. The analysis process may output a first confidence interval value representing a likelihood of the presence of one or more Enterobius vermicularis eggs within the sample. The one or more analysis computation servers may communicate the first confidence interval value to the personal electronic device.
