  • System and method for correcting bias in measurements in an imaging system from non-stationary noise in channelized hotelling observers
    Patent number: 11058392
    Abstract: Systems and methods for correcting images acquired with an imaging system for measurement bias from non-stationary noise in model observers are described. A biased detectability index is estimated from signal present and signal absent condition images and an estimate of the bias from non-stationary noise is also estimated. This bias is then removed from the detectability index to provide an assessment of detectability of the imaging system.
    Type: Grant
    Filed: December 19, 2017
    Date of Patent: July 13, 2021
    Assignee: Mayo Foundation for Medical Education and Research
    Inventors: Kenneth A. Fetterly, Christopher P. Favazza

  • REAL-TIME IN VIVO MEASUREMENT OF THE 3D ANGULAR ORIENTATION OF CARDIOVASCULAR STRUCTURES
    Publication number: 20150141807
    Abstract: This document provides materials and methods for determining three-dimensional spatial orientations of blood vessels, cardiac valves, and other anatomical structures within a mammal during a clinical procedure. For example, materials and methods for determining the three-dimensional spatial location, orientation, and size of a cardiac valve within a mammal during a trans-catheter cardiac valve implantation or replacement procedure are provided.
