Publication number: 20200046307Abstract: A method includes moving a radiation source and a radiation detector along a scan path substantially transverse to a longitudinal axis of a patient. A beam of radiation is emitted from the radiation source. The beam of radiation is detected at the radiation detector. The detected beam is processed so as to form a first image of a first area of the patient along the scan path.Type: ApplicationFiled: August 23, 2019Publication date: February 13, 2020Applicant: Hologic, Inc.Inventor: Kevin Wilson

Publication number: 20200046310Abstract: Synchronizing operation between a digital radiographic detector's integration periods and an x-ray generator's x-ray pulse rate by transmitting a frame rate to the detector and the generator. In a first mode, the detector monitors one or more pixels to detect an x-ray pulse. The firing time of the detected x-ray pulse relative to an internal clock of the detector is used to synchronize the detector's integration periods with the pulse rate of the x-ray generator based on the transmitted frame rate and the detected firing time of the x-ray pulses. Successive pulses may also be used to determine a frame rate without prior transmission thereof.Type: ApplicationFiled: November 22, 2017Publication date: February 13, 2020Inventors: Samuel RICHARD, Xiaohui WANG, Timothy J. WOJCIK, Nathan J. PACKARD

Publication number: 20200046311Abstract: A method for geometric calibration of a radiography apparatus acquires tomosynthesis projection images of patient anatomy from a detector and an x-ray source translated along a scan path. An epipolar geometry is calculated according to the relative position of the detector to the scan path by estimating a direction for epipolar lines that extend along an image plane that includes the detector. A region of interest of the patient anatomy that is a portion of each projection image and is fully included within each projection image in the series is defined. A consistency metric is calculated for estimated epipolar lines extending within the ROI. The method iteratively adjusts the epipolar line estimation until the consistency metric indicates accuracy to within a predetermined threshold. A portion of a tomosynthesis volume is reconstructed and displayed.Type: ApplicationFiled: April 2, 2019Publication date: February 13, 2020Inventors: Levon O. VOGELSANG, Richard A. SIMON, Lawrence A.

Publication number: 20200046312Abstract: Methods and implantable medical devices (IMDs) are provided for monitoring a cardiac function of a heart. A heart sound sensor is configured to sense heart sound signals of the subject. The IMD includes a memory to store program instructions. The IMD includes a processor that, when executing the program instructions, is configured to identify S2 signal segment from the heart sound signals, analyze the S2 signal segment to identify a pulmonary valve signal (P2 signal) and an aortic valve signal (A2 signal) within an S2 signal segment of the heart sound signals. The processor is configured to determine a time interval between the A2 and P2 signals, characterize the S2 signal segment to exhibit a first type of S2 split based on the time interval, and identify a cardiac condition based on a comparison of the first type of S2 split and a cardiac condition matrix.Type: ApplicationFiled: August 7, 2018Publication date: February 13, 2020Inventors: Xiaoyi Min, Kyungmoo Ryu, Stephanie C.
