摘要:
Automated sample analysis is performed by a computer-implemented apparatus and method for distinguishing objects of interest in an optical field from other objects and background in the optical field, collectively called background. Once an object has been identified, the color comprised of a combination of the red, green and blue components of the pixels occupied by the image of the object of interest, or another parameter of interest relative to that object can be measured and stored. This computer-implemented analysis apparatus and method is performed on objects of interest in the sample which are tagged using fluorescent tags. The sample may be a cell sample containing a nucleic acid target and the tagging achieved by fluorescence in situ hybridization.
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 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.

The present invention provides devices and methods for detection of particles, such as biological cells, in samples using a photosensitive waveguide. The photosensitive waveguide changes its transmissivity in a detectable manner in response to controlling radiation emitted from the particles. In preferred embodiments, the waveguide is two-dimensional and the position of the particles as well as their presence is obtained by scanning the waveguide in two non-parallel directions. The provided devices are preferably used to locate labeled cells. The present invention also includes control systems and methods for detecting and locating cells using the devices provided.

摘要:
A method for recognizing an object in an image is disclosed wherein a fractal map of the image is generated by estimating the fractal dimension of each pixel in the image. The fractal map may be segmented by thresholding and locations of candidate objects are determined. The pixel value of the image pixel corresponding to the same location where the candidate object is found in the fractal map may be compared to a threshold value. If the pixel value is greater than the threshold value, the candidate object is recognized as a valid object.
