  • Patent number: 12270749
    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: 12259311
    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: 20240280467
    Abstract: First waveform data, which indicates the morphological characteristics of a particle and is obtained by emitting light to the particle, and a photographic image obtained by photographing the particle are acquired. A first trained model that outputs a particle image when waveform data is input is generated by training using first training data including the first waveform data and the photographic image. Second waveform data is input to the first trained model. Classification information indicating a classification into which the particle is classified according to the morphological characteristics is acquired in association with the particle image output from the first trained model. Data including the second waveform data and the classification information is stored as second training data for training a second trained model that outputs classification information when waveform data is input.
