Publication number: 20100045698Abstract: A method is provided for displaying a client-side multi-component image. A plurality of image component channels derived from captured images of a sample are stored in a server, the plurality of image component channels being stored in the form of a plurality of image data records. A client then requests one or more of the plurality of image data records and the server transmits to the client the one or more of the plurality of image data records requested. At the client, the client-side multi-component image is composited from the image data records transmitted the composited client-side multi-component image is displayed.Type: ApplicationFiled: August 21, 2008Publication date: February 25, 2010Applicant: Applied Imaging CorporationInventors: Kevin Shields, James Raine, Gavin Hope

Patent number: 7133543Abstract: Scanning and analysis of cytology and histology samples uses a flatbed scanner to capture images of the structures of interest such as tumor cells in a manner that results in sufficient image resolution to allow for the analysis of such common pathology staining techniques as ICC (immunocytochemistry), IHC (immunohistochemistry) or in situ hybridization. Very large volumes of such material are scanned in order to identify cells or clusters of cells which are positive or warrant more detailed examination, and if analysis at higher resolution is necessary, information regarding these positive events is transferred to a secondary microscope, such as a conventional scanning microscope, to allow further analysis and review of the selected regions of the slide containing the sample.Type: GrantFiled: June 6, 2002Date of Patent: November 7, 2006Assignee: Applied Imaging CorporationInventors: Nico Peter Verwoerd, Johannes Vrolijk, Wilhelmina E. Mesker, Willem C. R. Sloos, Jan Bonnet, Padraig S. O'Kelly, Mark Gregson, Kevin Shields, Hendrikus J. Tanke

Patent number: 6633662Abstract: Detection of fetal nucleated red blood cells (NRBCs) is achieved by employing a combination of brightfield and fluorescence images of nuclear and cytoplasmic markers. The brightfield and fluorescence images are all obtained with a single multi-bandpass dichroic mirror. The objects in the sample are stained with a fluorescent dye that selectively stains nuclei and a dye that selectively stains fetal hemoglobin in the cytoplasm of fetal RBCs. UV excitation provides fluorescent emissions from the stained cell nuclei and visible illumination provides brightfield transmission of light that is absorbed by the stained cytoplasm. The images are processed to determine regions where the fluorescent emissions by cell nuclei in response to the UV excitation and the absorption by fetal hemoglobin of the brightfield illumination overlap or are in close proximity.Type: GrantFiled: July 9, 2001Date of Patent: October 14, 2003Assignee: Applied Imaging CorporationInventor: Ilya Ravkin

Patent number: 6524798Abstract: The invention provides a high efficiency method for combined immunocytochemistry and in situ hybridization. In one aspect, the method is used to simultaneously determining a cell phenotype and genotype by contacting a cell with an antigen-specific antibody bound to a ligand, contacting the cell with polynucleotide probe to form a complex of the probe and a nucleic acid in the cell, contacting the cell with a detectably labeled anti-ligand, and detecting the polynucleotide-probe complex and the anti-ligand-ligand complex. The presence of the anti-ligand is correlated with the presence of the antigen and the presence of the probe-nucleic acid complex is correlated with the presence of the nucleic acid in the cell.Type: GrantFiled: June 12, 2000Date of Patent: February 25, 2003Assignee: Applied Imaging CorporationInventors: Simon Goldbard, Tsai-Hsia Hong, Michael A. Zoccoli, Emily Lin

Patent number: 6270971Abstract: The invention provides methods and reagents for detecting a chromosomal aberration in an animal chromosome or karyotype. One or more detectably-labeled chromosome-specific probes from a first animal species are hybridized to chromosomes of a second animal species. This results in a banding pattern that can be compared to the pattern found in a normal chromosome or karyotype.Type: GrantFiled: June 30, 1999Date of Patent: August 7, 2001Assignee: Applied Imaging CorporationInventors: Malcolm A Ferguson-Smith, Johannes F Wienberg, Stefan Müller

Patent number: 6087134Abstract: Methods are provided for analyzing DNA of a rare cell in a cell population. In one embodiment, the method involves covering a cell monolayer with a photosensitive material. By illuminating the area over a cell of interest, the material is solidified, permitting manipulation of the underlying cell and/or protection of the cell from DNA-inactivating agents that destroy DNA in other cells in the monolayer. In another embodiment, the monolayer is overlaid with a solid material that becomes soluble when illuminated. By illuminating the area over a cell of interest, that cell can be specifically exposed and DNA from the cell amplified. The methods are particularly useful for analyzing fetal cells found in maternal blood.Type: GrantFiled: October 23, 1997Date of Patent: July 11, 2000Assignee: Applied Imaging CorporationInventor: Alexander Michael Saunders

Patent number: 5962234Abstract: An in vitro method of identifying or isolating fetal cells from a blood sample is described. Fetal nucleated erythrocytes or erythroblasts are identified by using an antibody or antibody fragment specific for embryonic hemoglobin or an embryonic hemoglobin chain. Once the fetal cells are identified, they can be treated to render the fetal nucleic acids or proteins available for identification or amplification. Detecting the occurrence or existence of selected fetal nucleic acids or proteins allows a quantitative or qualitative diagnostic or prenatal evaluation, including determining the sex of the fetus, determining chromosomal, single gene or protein abnormalities, and determining the presence or absence of particular genes, nucleic acid sequences or proteins.Type: GrantFiled: September 25, 1998Date of Patent: October 5, 1999Assignee: Applied Imaging CorporationInventor: Mitchell Golbus
