  • Patent number: 11788948
    Abstract: The present disclosure provides methods and systems for ghost cytometry (GC), which may be used to produce an image of an object without using a spatially resolving detector. This may be used to perform image-free ultrafast fluorescence “imaging” cytometry, based on, for example, a single pixel detector. Spatial information obtained from the motion of cells relative to a patterned optical structure may be compressively converted into signals that arrive sequentially at a single pixel detector. Combinatorial use of the temporal waveform with the intensity distribution of the random or pseudo-random pattern may permit computational reconstruction of cell morphology. Machine learning methods may be applied directly to the compressed waveforms without image reconstruction to enable efficient image-free morphology-based cytometry.

  • Publication number: 20230175949
    Abstract: An imaging flow cytometer includes: a flow channel in which an observation object flows and a length in a width direction is longer than a length in a height direction; an acoustic element configured to apply acoustic waves as standing waves to the flow channel; a light source that irradiates the flow channel with illumination light; an image sensor configured to image at least a line included in a cross section of the observation object crossing a flow line direction which is a direction in which the observation object flows in the flow channel by measuring or imaging the observation object passing through a position irradiated with the illumination light; and circuitry configured to generate an image in which the observation object is scanned in the flow line direction on the basis of a plurality of captured images acquired by the imaging unit imaging the line in a time series.

  • Patent number: 11630293
    Abstract: An imaging flow cytometer includes at least one flow channel through which an observation target flows, a light source which irradiates the flow channel with sheet-like excitation light, an imaging unit which images a specific cross-section of the observation target by imaging fluorescence from the observation target having passed through a position irradiated with the excitation light, and a three-dimensional image generation unit which generates a three-dimensional image of the observation target as a captured image on the basis of a plurality of captured images obtained by cross-sectional imaging by the imaging unit.

  • Patent number: 11598712
    Abstract: A cell evaluation system includes physical measurement unit, a database, and evaluation unit. The evaluation unit refers to a relevance stored in the database, searches reference measurement information based on measurement information of a cell newly measured via the physical measurement unit, and evaluates the cell with biological measurement information associated with the searched reference measurement information.
