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.

Abstract: During operation, a system may obtain first and second magnetic resonance (MR) measurements associated with a biological lifeform, where the first and second MR measurements were acquired while the biological lifeform engaged in free breathing and/or without prospective gating based on a cardiac rhythm of the biological lifeform, and the first and second MR measurements were acquired at different times. Then, the system may dynamically determine first and second instances of one or more anatomical structures associated with the biological lifeform based at least in part on the first and second MR measurements, and a segmentation technique. Next, the system may perform a quantitative comparison of the first instance of the one or more anatomical structures and the second instance of the one or more anatomical structures, where the quantitative comparison has an uncertainty of less than a predefined value.

Abstract: A method is proposed for recording diagnostic measurement data of a head of an examination object in head imaging via a magnetic resonance device.

Abstract: A computer system that performs a sparsity technique is described. During operation, the computer system accesses or obtains information associated with non-invasive measurements performed on at least an individual, historical non-invasive measurements, and a dictionary of predetermined features or basis functions associated with the historical non-invasive measurements. Note that the non-invasive measurements and the historical non-invasive measurements may include or correspond to magnetic resonance (MR) measurements. For example, the MR measurements may include magnetic resonance imaging (MRI) scans. Then, the computer system updates the dictionary of predetermined features based at least in part on the non-invasive measurements and the historical non-invasive measurements, where the updating includes performing a minimization technique with a cost function having an L2-norm term and an L0-norm term.

Abstract: Systems and methods for localized pseudo-continuous ASL (pCASL) of arterial blood local multi-coil arrays in an MRI system allow a series of pulses to selectively label blood with an on-resonance magnetic field in one or more arteries in a labeling plane while masking blood in others with an off-resonance magnetic field. This allows perfusion imaging and is well suited for imaging of cerebral blood flow.

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.

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.

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.
