Patent number: 7605356Abstract: A method of capturing a focused image of a continuously moving slide/objective arrangement is provided. A frame grabber device is triggered to capture an image of the slide through an objective at a first focus level as the slide continuously moves laterally relative to the objective. Alternatingly with triggering the frame grabber device, the objective is triggered to move to a second focus level after capture of the image of the slide. The objective moves in discrete steps, oscillating between minimum and maximum focus levels. The frame grabber device is triggered at a frequency as the slide continuously moves laterally relative to the objective so multiple images at different focus levels overlap, whereby a slide portion is common to each. The image having the maximum contrast value within overlapping images represents an optimum focus level for the slide portion, and thus the focused image. Associated apparatuses and methods are also provided.Type: GrantFiled: July 14, 2008Date of Patent: October 20, 2009Assignee: TriPath Imaging, Inc.Inventors: Bruno Krief, Raphaël Marcelpoil

Method for quantitative video-microscopy and associated system and computer software program product
Patent number: 7602954Abstract: A method of determining an amount of at least one molecular species in a sample from an image of the sample captured by an image acquisition device is provided, each molecular species being indicated by a dye. A dye space representation of a plurality of dyes is formed by orthogonally adding the correspondence tables of the dyes, each correspondence table having a plurality of normalized RGB triplets and incrementally extending from 0% to 100% transmittance. The dye space representation has one dimension for each dye and provides a reference model for a combination of the plurality of dyes. Each pixel of an image of the sample stained with the combination of the plurality of dyes is compared to the reference model, each pixel having a color defined by an RGB triplet, so as to determine an optimal combination of normalized RGB triplets from the respective correspondence tables of the dyes producing the color of the respective pixel.Type: GrantFiled: May 4, 2006Date of Patent: October 13, 2009Assignee: TriPath Imaging, Inc.Inventors: Raphaël Marcelpoil, Didier Morel -

Publication number: 20070076983Abstract: A method of re-locating an object in a sample is provided for a previously-scanned slide having determined objects each with corresponding stored coordinates and a stored image, the objects being mapped relative to each other. The slide is positioned on a microscope stage, stored images of the objects are visually displayed, and a target object is selected. The slide is moved to an estimated coordinate position, corresponding to the coordinates of the target object, and a field-of-view image of the sample is captured for comparison to the stored image of the target. If the target is in the image, an offset between actual coordinates of the located target and the stored coordinates of the corresponding object is determined. The slide is then moved, via the stage, from the estimated coordinate position, according to the offset, to center the target in the image. Associated systems and methods are also provided.Type: ApplicationFiled: June 12, 2006Publication date: April 5, 2007Applicant: TriPath Imaging, Inc.Inventor: Rainer Doerrer
