Publication number: 20240320879Abstract: The current disclosure provides systems and methods for increasing a quality of medical images via a recommendation system that recommends appropriate parameter settings to a user of a medical imaging system. In one example, a hybrid recommendation system for recommending a parameter setting for acquiring and/or reconstructing an image via a Positron Emission Tomography (PET) system comprises a first model trained to predict a parameter setting based on a preliminary reconstructed image; and a second model trained to customize the predicted parameter setting based on a preference of a user of the hybrid recommendation system.Type: ApplicationFiled: March 22, 2023Publication date: September 26, 2024Inventors: Abolfazl Mehranian, Scott Wollenweber, Kuan-Hao Su, Robert John Johnsen, Floribertus P Heukensfeldt Jansen

Patent number: 9424644Abstract: Methods and systems for evaluating bone lesions include accessing a first dataset acquired from a patient with a first imaging modality and a second dataset acquired from the patient with a second imaging modality. A segmentation is performed on the first dataset to identify a subset of the first dataset corresponding to a skeletal structure of the patient and a patient skeletal metric representing a total bone volume of the patient is automatically calculated from the subset of the first dataset. The methods and systems further include detection of at least one lesion in the second dataset, classification of the at least one lesion as a bone or non-bone lesion, automatic calculation of a bone lesion metric based on the classification, and calculation of a lesion burden as a ratio of the bone lesion metric and the patient skeletal metric.Type: GrantFiled: February 15, 2016Date of Patent: August 23, 2016Assignee: General Electric CompanyInventors: Pal Csongor Sprencz, Robert John Johnsen, Istvan Ubelhart, Elizabeth Philps, Andras Kriston, Andrea Fazekas

Patent number: 8917268Abstract: A method for automatically displaying an organ of interest includes accessing a series of medical images acquired from a first imaging modality, receiving an input that indicates an organ of interest, automatically detecting the organ of interest within at least one image in the series of medical images, automatically placing a visual indicator in the region of interest, and automatically propagating the visual indicator to at least one image that is acquired using a second different imaging modality. A medical imaging system and a non-transitory computer readable medium are also described herein.Type: GrantFiled: November 11, 2011Date of Patent: December 23, 2014Assignee: General Electric CompanyInventors: Robert John Johnsen, Istvan Ubelhart, Ferenc Kovacs, Andras Kriston, Tamas Blaskovics

Publication number: 20140094679Abstract: A method for automatically detecting an organ of interest that includes accessing a medical image dataset using a processor, automatically segmenting the medical image dataset to identify an outline of a body of a patient, automatically determining an axial reference image slice and a axial center point using the segmented body of the patient, automatically determining a location of the organ of interest using the axial reference image slice and the axial center point, and automatically placing a visual indicator in the organ of interest based on the determined location. A medical imaging system and a non-transitory computer readable medium are also described herein.Type: ApplicationFiled: October 3, 2012Publication date: April 3, 2014Applicant: General Electric CompanyInventors: Ferenc Kovacs, Andras Kriston, Tamas Blaskovics, William J.
