Patent number: 9835837Abstract: A method for estimating an in-focus position of a target using an image scanning apparatus is provided. The in-focus position is monitored at a seed location and an end location on the target and a pre-scan path is calculated between these locations. A pre-scan is then performed and a focus parameter is monitored for a plurality of locations along the pre-scan path. An imaging scan is next performed wherein the target is imaged along an image scan path and a focus parameter is monitored for a plurality of locations along said path. The focal height of the apparatus is adjusted during the imaging scan by comparing the focal parameter monitored for a current location on the image scan path with the focal parameter monitored for a similar location on the pre-scan path. The focal parameter monitored for different locations on the image scan path may also be compared.Type: GrantFiled: December 15, 2014Date of Patent: December 5, 2017Assignee: FFEI LimitedInventor: Martin Philip Gouch

Patent number: 8472692Abstract: In accordance with the present invention there is provided a method for controlling a microscope to scan a microscope slide. By analyzing an overview image it is determined quantatively which swathe contains the most image detail and an optimum scanning order can subsequently be determined relative to the swathe determined as having the most detail. By scanning the swathe with the most detail first a good focus characteristic can be established for a dynamic focussing system and prediction errors in the dynamic focus system are likely to be low when scanning subsequent swathes.Type: GrantFiled: January 11, 2010Date of Patent: June 25, 2013Assignee: FFEI LimitedInventors: Daxa Neykumar Rughani, Martin Philip Gouch
