    摘要: The invention relates to an apparatus and methods for generating multiparameter optical data that characterize a population of cells. The invention includes the steps of scanning the cell population with a beam to produce sets of digital data samples, each sample set of digital data representing multiparameter optical interactions from a specific location within the cell population; storing the digital data, e.g., in a computer memory; locating a cell within the population, e.g., by comparing the digital data to a preselected threshold value; defining a neighborhood around the digital data representing the located cell; estimating a background level for the neighborhood based upon digital data corresponding to locations outside the neighborhood; and correcting each of the samples corresponding to the neighborhood with the estimated neighborhood background level to generate the optical data. The invention further relates to specific methods of background correction and data calibration as well as specific sampling features to enable precise estimates of multiple cellular constituents or other cell properties at high rates of speed.

    摘要: A method for the accurate counting of DNA probe spots in cell nuclei wherein anomalies caused by a two dimensional measurement of a three dimensional cell sample are eliminated from evaluation. DNA probe spots in cell nuclei which are counted by means of Fluorescent In Situ Hybridization (FISH) include cells wherein probe spots of different contoured cells are overlaid or are detected as being adjacent one another with resultant erroneous diagnostic results such as with cancer detection or prognosis. A gating fluorescent value is determined by clusters of fluorescence in regions of non-anomalous values of fluorescence determined by plotting peak fluorescent value against area. The loci of the non-anomalous peak values cluster in specifically definable regions whereby fluorescent values for cells which deviate from the gating fluorescent value, are discounted in the preparation of histograms or other diagnostic measurements.

    摘要: A network system for review and analysis of computer encoded microscope slides and specimens which were originally computer encoded from a microscope (attached via an encoder device to a local computer site), during an initial examination. The encoding includes parameters of viewing locations and events of interest on the slide, with such information being stored on a networked file server. The encoding also includes information regarding the manner in which the initial examination was conducted, for quality control purposes. The computer encoded information is retrievable at all remote locations of the network (either local or connected via modem) for supervisor review or for pathologist analysis. The network is further constituted by microscope sites having similar computer encoding devices attached thereto, which function, in this aspect, as computer terminals of the network. For enhanced analysis, the computer terminals have direct access to patient background information, e.g., such as from an HIS (hospital information system) for simultaneous slide analysis review in relation to the medical history of the patient. For diagnostic support, the computer terminals are networked with an on-line library of cell type images for comparison with the slide being examined. Slide diagnosis is either directly with the original slide on the microscope or with a scanned image of the slide stored in the network server or CD-ROM and retrieved on the computer terminal. The microscope is optionally motor driven, with computer control, to re-scan slides or slide images only at designated sites.

    摘要: A method of characterizing the chromosomes in a sample of cells by fixing the cell sample on a substrate, contacting the cell sample with a nucleic acid probe having a detectable label under conditions that allow the probe to hybridize preferentially to a chromosome in the cells to form a hybridized complex, optically detecting each labeled complex in the sample, defining a predetermined number of neighboring labeled complexes as a group, generating a distance parameter based on the distance between the position of a group and the position of the next neighboring labeled complex, and comparing the distance parameter for each group to a standard distance value to characterize the chromosomes in the cells of the sample.

    摘要: A computerized specimen encoder for use with microscope analysis and pathological studies. The slide encoder is attached to the movable microscope stage, whereby X-Y plane movement and location, is correlated to examination of a specimen on an identified slide, with information marking and location being directly correspondingly written on computer storage media, during the examination. The information marking is in the form of computer generated indicia which are placed at a computer image location of the slide at predetermined time intervals. Subsequent use of the computer-stored information, coupled with the slide encoder, in a slide re-examination, permits independent retrieval of such information and location on the slide. The encoder device is provided with a grayscale marker which marks in varying shades of gray, ranging from white to black, the time spent by a slide screener on a particular portion of the specimen and the number of times spent viewing a particular portion of the specimen.

    摘要: Cell samples, stained with a fluorescent dye, taken up by DNA in the individual cells, are scanned with a cytometer, which measures the integrated value of fluorescent light/cell. The integrated values of all of the cells are compiled to create an histogram of cell counts versus integrated fluorescent light, representing a cell population of (a) cells having a complement of DNA, but not in the process of division (G.sub.0 phase), (b) cells having two full compliments of DNA, but which have not actually divided into two cells (G.sub.2 phase) and (c) cells which are in the process of replicating their DNA (S, separation phase). The percentages of cells in each of the phases, represented in the histogram as separated peaks of sizes proportional to the G.sub.0 and G.sub.2 populations, and separation S phase population, aids in the prognosis of a patient's cancer development. More serious malignancy is indicated by increased S and G.sub.2 phase populations. Errors, e.g., resulting from statistical errors, focusing problems, inaccurate measurement of background, etc., in the integrated values and compilation of cells in the histogram, affect the accuracy and prognostic value of the peaks and separation phase, and are corrected by a method, wherein the convolution of error function with the signal function (representing the number of cells, as determined by the florescence measurements, with a DNA content of a specified value), is modeled and the error function removed, by deconvolution, from the G.sub.0 and G.sub.2 peaks and the S phase.
