Patent number: 11141044Abstract: A method and apparatus are provided for estimating the value of a physical parameter of biological tissue. The method comprises acquiring a colour image of the biological tissue from a single image capture device; extracting from the colour image at least two images in respective optical wavebands having a different spectral sensitivity from one another, whereby a given location in the biological tissue is present in each of the extracted images; providing a physical model of the optical properties of the biological tissue, wherein the optical properties of the biological tissue are sensitive to the value of said physical parameter; and estimating the value of the physical parameter at said given location based on an intensity value at that location for each extracted image. The estimating utilises the physical model of the optical properties of the biological tissue and the spectral sensitivity for each respective waveband.Type: GrantFiled: June 19, 2017Date of Patent: October 12, 2021Inventors: Geoffrey Jones, Danail Stoyanov, Dan Elson, Neil Clancy

Patent number: 10496898Abstract: A set of virtual images can be generated based on one or more real images and target rendering specifications, such that the set of virtual images correspond to (for example) different rendering specifications (or combinations thereof) than do the real images. An image style can be transferred to the at least some of the virtual images of the set of virtual images to generate a stylized virtual image. A machine-learning model can be trained using a plurality of stylized virtual images. Another real image can then be processed using the trained machine-learning model. The processing can include segmenting the other real image to detect whether and/or which objects are represented (and/or a state of the object). The object data can then be used to identify (for example) a state of a procedure.Type: GrantFiled: February 1, 2019Date of Patent: December 3, 2019Assignee: Digital Surgery LimitedInventors: Odysseas Zisimopoulos, Evangello Flouty, Imanol Luengo Muntion, Mark Stacey, Sam Muscroft, Petros Giataganas, Andre Chow, Jean Nehme, Danail Stoyanov
