Patent number: 8749627Abstract: A method and apparatus for acquiring digital microscope images is disclosed, in which a plurality of magnified images of a specimen are captured for tiling together to provide an overall composite image of the specimen. In accordance with the described method, the specimen is moved relative to an imaging system comprising a microscope and camera in a predetermined path while the plurality of magnified images are captured. In a preferred embodiment, the specimen, contained on a slide, is mounted on a movable microscope stage, and is moved beneath the microscope in the predetermined path. The velocity of the movement of the stage and the shutter speed of the camera is computer controlled to capture overlapping, clear images.Type: GrantFiled: July 31, 2012Date of Patent: June 10, 2014Assignee: Source Bioscience PLCInventors: John R. Maddison, Noah F. Clinch

Patent number: 8478073Abstract: A method for determining a position of an area of an object within the complete object, wherein the image of the area of the object is contained within a field of view of a microscope. The method comprises acquiring high magnification image data representing an image of the field of view of the microscope, typically from a digital camera attached to the microscope; processing the high magnification image data to reduce the resolution thereof; comparing the processed high magnification image data with portions of the low magnification image data, and determining said position based on the results of said comparison.Type: GrantFiled: December 21, 2011Date of Patent: July 2, 2013Assignee: Hamamatsu Photonics K.K.Inventor: John R. Maddison

Patent number: 7248282Abstract: A microscopy imaging system and method acquires digital images of a microscope specimen using a computer-controlled microscope and digital camera. A specimen on a microscope slide is placed within the microscope. The method comprises the steps of determining whether an area of the specimen contained within a microscope field of view has a thickness, and, if so, capturing digital images of the field of view at a plurality of depths of focus. In a preferred embodiment, the step of determining whether an area of the specimen contained within a microscope field of view has a thickness comprises the steps of: capturing a digital image of the field of view at two or more depths of focus; comparing the captured digital images, and determining that the specimen has a thickness, if the comparing step finds that the images are different. The method may be implemented in the form of a computer program.Type: GrantFiled: February 12, 2003Date of Patent: July 24, 2007Assignee: Fairfield Imaging LimitedInventor: John R Maddison

Patent number: 6847729Abstract: A method of telemicroscopy comprises the step of preparing a specimen on a microscopy slide. The slide is placed upon the stage of a microscope equipped with digital imaging apparatus and motorised stage and the specimen imaged to obtain a composite high resolution image of the whole specimen. A relatively low resolution copy of that image is obtained and stored in a datastore. The method further comprises the steps of allowing access to the datastore from a terminal transferring the low resolution image to the terminal and displaying the image upon a monitor selecting by means of the remote terminal, as desired, an area of the low resolution image and transferring corresponding high resolution image data for that area from the datastore to the terminal.Type: GrantFiled: April 20, 2000Date of Patent: January 25, 2005Assignee: Fairfield Imaging LimitedInventors: Noah Clinch, John R.
