  • Publication number: 20220179024
    Abstract: Described here are systems and methods for producing images with a magnetic resonance imaging (“MRI”) system using a high-resolution, motion-robust, artifact-free segmented echo planar imaging (“EPI”) technique. In particular, a fast low angle excitation echo planar imaging technique (“FLEET”) using variable flip angle (“VFA”) radio frequency (“RF”) excitation pulses that are recursively designed to have a flat magnitude and phase profile across a slice for a range of different flip angles by accounting for longitudinal magnetization remaining after each preceding RF pulse is applied.

  • Patent number: 10908248
    Abstract: Systems and methods for simultaneously acquiring high-resolution images of a subject from multiple different slice locations using magnetic resonance imaging (“MRI”) are described. The present invention overcomes the aforementioned drawbacks by providing method for producing a plurality of images of a subject with a magnetic resonance imaging (“MRI”) system. A radio frequency (RF) excitation field is applied by the MRI system to a portion of a subject that includes a plurality of slice locations. First data are simultaneously acquired from each of the plurality of slice locations by the MRI system.

  • Patent number: 10565226
    Abstract: An Application Program Interface (API) manages synchronization and replication of master data of a system with different consumers. An API engine is configured to receive from the third party, a query including content information and date-relevant information including a start date, an end date, and a date of last synchronization. The API engine processes the query to access the database and produce a query result replicating only data changes affecting that period or a previous time. The consumer thus specifies the time period in which to consider changes to the stored database data, and the API calculates the delta according to that period. In this manner complex, time-dependent delta calculation and filtering logic can be implemented in the API without requiring substantial logic or additional data persistence in middleware. Particular embodiments may facilitate efficient synchronized replication of employment data to outside (e.g., payroll, benefits) providers.

  • Patent number: 9983282
    Abstract: Spin-lock T1?-weighted images of a subject are acquired and processed to produce an image that is indicative of bioelectromagnetic activity in the subject. A spin-lock RF field B1? is produced such that the Larmor frequency in the rotating frame corresponds to the expected frequency of the bioelectromagnetic activity. As a result, the magnetic field fluctuations generated by the bioelectromagnetic currents shorten the T1? of the surrounding tissue, creating a contrast mechanism that is seen as a reduced MR signal in the T1?-weighted image that is produced.

  • Patent number: 9588208
    Abstract: A method for accelerated segmented magnetic resonance (MR) image data acquisition includes using a plurality of RF pulses to excite one or more slices of an anatomical area of interest according to a predetermined slice acceleration factor. Next, a collapsed image comprising the slices is acquired using a consecutive segment acquisition process. Then, a parallel image reconstruction method is applied to the collapsed image to separate the collapsed image into a plurality of slice images.

  • Patent number: 8849372
    Abstract: A method and system for producing an image of a subject with a magnetic resonance imaging (MRI) system, in which the presence of a contrast agent is detected using a spin-lock pulse sequence, is described. More specifically, a contrast agent that induces saturation of magnetic resonance signals responsive to a spin-lock condition is administered to a subject. A spin-lock condition is subsequently established to saturate spins in proximity to the contrast agent. Image data is then acquired with an imaging pulse sequence and images indicative of the presence of the contrast agent are reconstructed.
