Patent number: 9865067Abstract: The present invention relates to a method of reconstruction of an object from projections, more particularly to a quantitative reconstruction of an object from projection views of the object. For example, quantitative reconstruction of an image of a human breast from projection views generated by digital breast tomosynthesis (DBT), computed tomography (CT), or standard mammography, and use of the reconstruction to identify densest regions.Type: GrantFiled: June 6, 2014Date of Patent: January 9, 2018Assignee: VOLPARA HEALTH TECHNOLOGIES LIMITEDInventors: Ralph Highnam, John Michael Brady

Patent number: 9361683Abstract: The present invention relates to an imaging technique and an imaging system and more particularly to an automatic assessment of quantitative measure(s)/properties(s) of an object wherein, for example, an imaging system is used to capture an image, following which image properties are quantified using image processing techniques. An imaging technique obtains an image of an object along a first axis, or by way of a first technique, and subsequently obtains an image of the object along a second axis, or by way of a second technique. One or more pixels from the first image are selected and designated as reference pixels. An automated comparison between corresponding regions of the first and second images are then performed which is based upon the reference pixels, so as to indicate regions of interest.Type: GrantFiled: November 29, 2011Date of Patent: June 7, 2016Inventors: Ralph Highnam, John Michael Brady

Patent number: 9008382Abstract: Disclosed is a method of analyzing tissue from an image comprising providing an electronic image of tissue (100, 400, 450, 600, 800, 1100), determining a reference value from the image (1070, 1170, 1270), establishing an hint representation (500,700) of the image, and using the hint representation in analysis of the tissue to quantify the breast and compute a calibration error. Also disclosed is a system which runs an inner breast edge detection algorithm (1310) on the electronic image to detect the inner breast edge on the image (1315), and refined the inner breast edge location (1340) if a calibration error is not acceptable (1324). Also disclosed is automatic estimation of breast composition and temporal analysis of images.Type: GrantFiled: August 3, 2010Date of Patent: April 14, 2015Inventors: Ralph Highnam, John Michael Brady, Nico Karssemeijer, Martin Yaffe

Patent number: 8948481Abstract: A signal processing method that includes inputting sample values of a signal and considering the signal to have a plurality of portions. For each portion, a predetermined function is fitted to the sample values of that portion of the signal by calculating values of coefficients for that predetermined function. At least one statistical information function is evaluated for the signal to determine statistical information about the signal and the calculated coefficient values are used so that the form of the statistical information function has been determined for the predetermined function used to fit the signal portion and further includes using the statistical information obtained about the signal to process the signal.Type: GrantFiled: September 14, 2012Date of Patent: February 3, 2015Assignee: Mirada Medical Ltd.Inventors: Timor Kadir, John Michael Brady
