    摘要: A system for performing high-speed, high-resolution imaging cytometry utilizes a line-scan sensor. A cell to be characterized is transported past a scan region. An optical system focuses an image of a portion of the scan region onto at least one linear light sensor, and repeated readings of light falling on the sensor are taken while a cell is transported though the scan region. The system may image cells directly, or may excite fluorescence in the cells and image the resulting light emitted from the cell by fluorescence. The system may provide a narrow band of illumination at the scan region. The system may include various filters and imaging optics that enable simultaneous multicolor fluorescence imaging cytometry. Multiple linear sensors may be provided, and images gathered by the individual sensors may be combined to construct an image having improved signal-to-noise characteristics.

    摘要: Photometric and morphometric features derived from multi-mode imagery of cells in flow are used as a cell analyzer to determine if a marker corresponding to a cancer cell or precancerous cell is present in the population of cells imaged. An imaging system simultaneously acquires a plurality of images for each cell passing through the field of view of the imaging system. Acquiring a plurality of different images (i.e., bright field, dark field, and fluorescent images) facilitates the determination of different morphological and morphometric parameters. Simultaneously acquiring the plurality of images enables relatively large populations of cells to be rapidly imaged, so that relatively small numbers of cancer cells in a large population of cells can be detected. Initially, known cancer cells are imaged to enable a marker to be identified. Then, a sample that may include cancer cells is imaged to determine if the marker is present.

    摘要: A method may include accessing data regarding a number of events, where the events were detected by a particle detection apparatus, and identifying a number of groups in the events. Each of the groups includes two or more events, and each event includes one or more of a time stamp, a time duration, a fluorescence intensity, a scatter measurement, a radio frequency signal, a magnetic signal, a neutron scattering measurement, a light scattering measurement, an electron scattering measurement, an audio signal, an acoustic signal, a mechanical signal, an electrical resistance, a thermal property, and a width of fluorescence signal. The method may include identifying a subset of the groups as a number of objects detected by the particle detection apparatus, where each object is identified based at least in part upon one or more quantities, where each quantity is identified by or derived from the respective two or more events.
