摘要: A single-particle localization microscope includes a light source configured to generate illumination light for illuminating a sample region, and an optical illumination system configured to shape the illumination light into a localizing light distribution having a substantially zero intensity minimum at a target point within the sample region. The localizing light distribution is adapted to cause a single particle in a fluorescent state located in the sample region outside the intensity minimum to emit fluorescent light. The optical illumination system is further configured to shape the illumination light into an auxiliary light distribution having a non-zero intensity at the target point such that the auxiliary light distribution is defined in a spatial extent and/or in its shape by the localizing light distribution.

The dome is configured to surround at least a portion of a tissue sample. The dome has interior surfaces that define a dome interior cavity. The excitation light source is configured to produce light at one or more wavelengths. The excitation light source is in photometric communication with the dome. The dome interior surfaces are configured to reflect the light at the one or more predetermined wavelengths. The dome is configured to cause the light at the one or more predetermined wavelengths to be incident to the exposed surface of the tissue sample in a substantially uniform manner. The light detector is in photometric communication with the dome and configured to detect light emitted or reflected from the tissue sample.

摘要: Techniques are described for reducing the number of angles needed in structured illumination imaging of biological samples through the use of patterned flowcells, where nanowells of the patterned flowcells are arranged in, e.g., a square array, or an asymmetrical array. Accordingly, the number of images needed to resolve details of the biological samples is reduced. Techniques are also described for combining structured illumination imaging with line scanning using the patterned flowcells.

摘要: A method can be used for correcting background signals in captured measurement values of analog detectors, wherein measurement values of an object captured over a reference time period are analyzed and characteristic values of captured background signals are determined. What is characteristic of this is that a threshold value is determined on the basis of at least one characteristic value and by applying a calculation specification; the threshold value is applied to captured measurement values of an analog detector, and only those measurement values which are greater than the threshold value are used for a subsequent signal evaluation. A microscope for carrying out the method according to the invention is also provided.

摘要: The disclosed technology brings histopathology into the operating theatre, to enable real-time intra-operative digital pathology. The disclosed technology utilizes confocal imaging devices image, in the operating theatre, “optical slices” of fresh tissue—without the need to physically slice and otherwise process the resected tissue as required by frozen section analysis (FSA). The disclosed technology, in certain embodiments, includes a simple, operating-table-side digital histology scanner, with the capability of rapidly scanning all outer margins of a tissue sample (e.g., resection lump, removed tissue mass). Using point-scanning microscopy technology, the disclosed technology, in certain embodiments, precisely scans a thin “optical section” of the resected tissue, and sends the digital image to a pathologist rather than the real tissue, thereby providing the pathologist with the opportunity to analyze the tissue intra-operatively. Thus, the disclosed technology provides digital images with similar information content as FSA, but faster and without destroying the tissue sample itself.
