Patent number: 11972563Abstract: An imaging system and method acquires non-contrast images of a region of interest in a body and determines an entrance criterion based on the non-contrast images. The entrance criterion dictates conditions in which to begin acquiring contrast imaging exposures of the region of interest. An amount of a contrast agent is measured in one or more locations in the imaged body subsequent to acquiring the non-contrast images. The system and method determine that the one or more conditions of the entrance criterion are met based on the amount of the contrast agent that is measured in the imaged body, and acquire one or more contrast images of the region of interest in the imaged body responsive to determining that the one or more conditions of the entrance criterion are met.Type: GrantFiled: April 18, 2022Date of Patent: April 30, 2024Assignee: General Electric CompanyInventors: John Irvin Jackson, Amy Deubig, John Londt, Christine Carol Hammond, Scott McOlash, Vignesha Ramegowda

Publication number: 20230214452Abstract: Systems and methods describe dwell time recording of digital image review sessions. The system displays, at a user interface (UI), a portion of an image on at least one monitor, where the image is segmented into a multitude of patches. The system then receives UI events involving a change in the currently displayed patches. For each of the UI events, the system records one or more dwell times representing durations for which the current patches of the image were displayed. The system also receives a report associated with the image review session, and processes the text of the report to determine a classification label for the image. Finally, the system trains a machine learning model, using at least the recorded dwell times and the classification label for the image.Type: ApplicationFiled: December 31, 2021Publication date: July 6, 2023Inventors: John Irvin Jackson, Ketan Bacchuwar, Jayendra Shinde

Publication number: 20230130015Abstract: Methods and systems are provided for cardiac computed tomography imaging. In one embodiment, a method comprises reconstructing an image from projection data acquired during a scan with a reconstruction time determined based on a model relating a timing of an event to be imaged to a heart rate measured during the scan. In this way, the timing of a reconstruction may be consistently applied for a series of reconstructions, thereby inherently registering the reconstructions.Type: ApplicationFiled: December 22, 2022Publication date: April 27, 2023Inventors: John Irvin Jackson, Mark Edward Woodford

Patent number: 10475216Abstract: An imaging system determines a heart rate of a patient, a cardiac disease state, and/or a target cardiac anatomy of the patient. The system calculates an image acquisition time range from a patient population model using the heart rate, the cardiac disease state, and/or the target anatomy. The model represents relationships between cardiac motion of other patients and time or cardiac phases of the other patients. The system also determines imaging settings to acquire image data of the target anatomy during the image acquisition time range that is calculated. Imaging the target anatomy of the patient according to the imaging settings generates image data of the target anatomy having less cardiac motion and/or a reduced image acquisition time range relative to determining the imaging settings without using the patient population model.Type: GrantFiled: February 26, 2018Date of Patent: November 12, 2019Assignee: General Electric CompanyInventors: John Irvin Jackson, John Londt, Eric Gros, Dave Chevalier
