Patent number: 11890123Abstract: A multimodal system for breast imaging includes an x-ray source, and an x-ray detector configured to detect x-rays from the x-ray source after passing through a breast. The system includes an x-ray detector translation system operatively connected to the x-ray detector so as to be able to translate the x-ray detector from a first displacement from the breast to a second displacement at least one of immediately adjacent to or in contact with the breast. The system includes an x-ray image processor configured to: receive a CT data set from the x-ray detector, the CT data set being detected by the x-ray detector at the first displacement; compute a CT image of the breast; receive a mammography data set from the x-ray detector, the mammography data set being detected by the x-ray detector at the second displacement; and compute a mammography image of the breast.Type: GrantFiled: December 30, 2022Date of Patent: February 6, 2024Assignee: The Regents of the University of CaliforniaInventors: John M. Boone, George W. Burkett

Publication number: 20240016466Abstract: Embodiments provide a modular phantom that enables quantitative assessment of imaging performance (e.g., spatial resolution, image uniformity, image noise, contrast to noise ratio, cone-beam artifact) and dosimetry in cone-beam computed tomography (CT). The modular phantom includes one or more modules for various imaging performance tests that may be rearranged in the phantom to accommodate the design of various cone-beam CT imaging systems. The modular phantom includes one or more of a cone-beam module, an angled edge module, or a line spread module. The phantom may be inserted into a larger sleeve and be used to assess imaging performance and dosimetry in whole body CT imaging systems.Type: ApplicationFiled: March 7, 2023Publication date: January 18, 2024Inventors: John M. BOONE, Jeffrey H. SIEWERDSEN, George W. BURKETT

Patent number: 9008264Abstract: Described is an apparatus for use in HVL measurement as well as methods of making measurements. One version of the apparatus is a cage structure having a central axis and a central opening defined by a filter encircling the central axis, with the filter having a thickness that varies peripherally around said central axis. The filter can be formed from multiple spaced-apart plates having varying thicknesses or can be formed from a cylinder having a continuously increasing thickness.Type: GrantFiled: July 16, 2012Date of Patent: April 14, 2015Assignee: The Regents of the University of CaliforniaInventors: John M. Boone, George W. Burkett, Jr., Sarah E. McKenney
