Patent number: 11686797Abstract: A method of controlling and processing data from a hybrid PET-MR imaging system includes acquiring a positron emission tomographic (PET) dataset over a time period, wherein the PET dataset is affected by a quasi-periodic motion of the patient, and acquiring magnetic resonance (MR) data during the time period such that the acquisition time of the MR data relative to the PET dataset is known. A characteristic of the patient motion is then determined based on the PET dataset and the MR data is processed based on the characteristic of patient motion.Type: GrantFiled: November 23, 2020Date of Patent: June 27, 2023Assignee: GE Precision Healthcare LLCInventors: Timothy W. Deller, Florian Wiesinger, Floribertus P. Heukensfeldt Jansen, Anja C. S. Brau, Kristen Ann Wangerin

Patent number: 11179128Abstract: Methods and systems are provided for medical imaging systems. In one embodiment, a method for a medical imaging system comprises acquiring emission data during a positron emission tomography (PET) scan of a patient, reconstructing a series of live PET images while acquiring the emission data, and tracking motion of the patient during the acquiring based on the series of live PET images. In this way, patient motion during the scan may be identified and compensated for via scan acquisition and/or data processing adjustments, thereby producing a diagnostic PET image with reduced motion artifacts and increased diagnostic quality.Type: GrantFiled: December 31, 2019Date of Patent: November 23, 2021Assignee: GE Precision Healthcare LLCInventors: Floribertus P. Heukensfeldt Jansen, Timothy Wayne Deller, Kristen Ann Wangerin, Matthew Spangler-Bickell

Patent number: 8575555Abstract: A Nuclear Medicine (NM) imaging system and method using multiple types of imaging detectors are provided. One NM imaging system includes a gantry, at least a first imaging detector coupled to the gantry, wherein the first imaging detector is a non-moving detector, and at least a second imaging detector coupled to the gantry, wherein the second imaging detector is a moving detector. The first imaging detector is larger than the second imaging detector and the first and second imaging detectors have different detector configurations. The NM imaging system further includes a controller configured to control the operation of the first and second imaging detectors during an imaging scan of an object to acquire Single Photon Emission Computed Tomography (SPECT) image information such that at least the first imaging detector remains stationary with respect to the gantry during image acquisition.Type: GrantFiled: March 31, 2011Date of Patent: November 5, 2013Assignee: General Electric CompanyInventors: Kristen Ann Wangerin, Evren Asma, Jorge Uribe, Ravindra Manjeshwar

Patent number: 8466420Abstract: The present disclosure relates to the correction of charge loss in a radiation detector. In one embodiment, correction factors for charge loss may be determined based on depth of interaction and lateral position within a radiation detector of a charge creating event. The correction factors may be applied to subsequently measured signals to correct for the occurrence of charge loss in the measured signals.Type: GrantFiled: June 4, 2010Date of Patent: June 18, 2013Assignee: General Electric CompanyInventors: Kristen Ann Wangerin, Wen Li, Yanfeng Du, Floribertus Heukensfeldt Jansen

Publication number: 20120080414Abstract: A method for laser patterning a sample is presented. The method includes coating at least one side of a substrate to form a sample, where coating the at least one side of the substrate forms an interface between the coating and the at least one side of the substrate. Further, the method includes configuring a scanning pattern for patterning the sample. In addition, the method includes determining settings for one or more laser beams of a laser based on the configured scanning pattern. Moreover, the method includes focusing the one or more laser beams of the laser at or near a surface of the substrate by selecting a focal point of the one or more laser beams near the surface of the substrate and setting a scribe depth near the surface of the substrate. The method also includes patterning the sample based on the configured scanning pattern using the one or more laser beams to generate one or more pixelated devices from the sample.Type: ApplicationFiled: September 30, 2010Publication date: April 5, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: Wenwu Zhang, Christopher James Kapusta, Floribertus P.
