摘要:
A computer controlled method for detecting and diagnosing a rare cell type in a tissue sample is provided, said method comprising treating the tissue sample such that it generates a first signal indicative of the presence at a location of a rare cell, detecting the first signal, treating the location at which the first signal is detected to generate a second signal indicative of a diagnostically useful cellular characteristic and detecting the second signal. The first signal can be morphological or a color present in a sought cell either before or after staining. The second signal can be generated by in situ PCR or PCR in situ hybridization. In one preferred embodiment, the rare cell type is a fetal cell in a maternal blood tissue sample, said sample consisting of a smear of unenriched maternal blood. In another embodiment, the method is used to diagnose or genotype cancer cells in a blood or tissue biopsy sample.

A method for automated microscopic analysis wherein the test protocol is obtained from interrogatable data affixed to each microscope slide. The method further comprises the algorithms that implement the test protocol.
摘要:
A method for detecting and quantitating multiple and unique fluorescent signals from a cell sample is provided. The method combines immunohistochemistry and a fluorescent-labeled in situ hybridization techniques. The method is useful for identifying specific subcellular components of cells such as chromosomes and proteins.

摘要:
The contrast of an image produced by epifluorescence microscopy may be increased by placing a high-pass dichroic reflecting film behind the sample. The reflecting film reflects the emission light emitted by the fluorescent tags in the sample back through the objective lens while allowing the shorter wavelength excitation light to pass through the sample holder.

The present invention provides a composing microscope for scanning a large area of a specimen in a minimal amount of time. In a first embodiment, the composing microscope has a plurality of optical sensors and a plurality of optical projecting systems arranged adjacent to each other. Each of the projecting systems acquires an image from one location of a specimen and projects the image on one of the optical sensors for digitalizing the image. An image acquisition device is connected to the optical sensors for simultaneously storing the digitalized images with information of their locations on the specimen. In a second embodiment, a composing microscope has an optical sensor and a plurality of optical projecting systems arranged adjacent to each other in rows. Each of the optical projecting systems has a first end for acquiring an image at one location of a specimen and a second end. An optical reflector moveable with respect to the second ends of the optical projecting systems receives the images from a row of the optical projecting systems at the second ends and projects the images on the optical sensor, and the optical sensor simultaneously digitalizes the images. An image acquisition device simultaneously receives and stores the digitalized images with information of their locations on the specimen. In a third embodiment, a composing microscope has an optical sensor and a plurality of optical projecting systems arranged adjacent to each other. The projecting system has a first end and a second end connected to the optical sensor. Each of the optical projecting systems acquires an image of one location of a specimen at the first end and projects the image on the optical sensor for digitalizing the image. An image acquisition device is connected to the optical sensor for storing the digitalized images with information of their locations on the specimen.
