摘要： A communication and data processing system for use between one or more employers and one or more service providers, at least including a mathematical model for calculating a quantity Hi(T), where Hi(T) denotes a size of a fee to the one or more service providers and T denotes the true time use. Calculating Hi(T) at least includes using the following manipulated parameters: TN, estimated time for completing the project; T, actual time for completing the project; Z, chosen portion of total project value; and at least one parameter indicative of real-time data for the project. The communication and data processing system is implemented as an application on a computer, the application acquiring real-time data automatically at predetermined times and other parameters being entered manually via a user interface.

摘要： A parallel magnetic resonance imaging system (1) includes at least one radio frequency (RF) coil (10, 12) with a plurality of coil elements, a smart select unit (24), a parallel imaging parameter unit (28), and a sequence control (16). The smart select unit (24), from a pre-scan or prior scan of a subject with the at least one RF coil, constructs (60) a signal map and a plurality of noise maps based on different sets of reduction factors. The parallel imaging parameter unit (28) selects a set of reduction factors corresponding to a noise map which includes a highest signal-to-noise ratio (SNR). The sequence control (16) performs a magnetic resonance imaging scan of the subject based on the selected reduction factors.

摘要： A method and system that allows healthcare providers, hospitals, skilled nursing facilities and other persons to monitor disabled, elderly or other high-risk individuals to prevent or reduce falls and/or mitigate the impact of a fall by delivering automated notification of “at risk” behavior and falls by such an individual being monitored where assistance is required. The monitored individual is virtually represented as a blob object of at least a specific size by a computerized monitoring system and such system detects and alerts when the blob object enters or crosses into a virtually defined or designated blob detection zone and remains in the zone for at least a predetermined period of time.

摘要： A system and method is described to measure the magnetic field gradient using an optically pumped magnetometer configured as an intrinsic gradiometer. Atoms are prepared in a freely precessing coherent superposition of the magnetically sensitive hyperfine ground states in two or more physically separated locations. A probe laser beam is used to interrogate atoms in both locations. As the probe light beam passes through the coherent atoms, optical sidebands are self-generated at the ground state hyperfine frequency of the magnetically sensitive states. Each of the two sets of atoms produces distinct sidebands at a frequency separation proportional to the magnetic field experienced by each set of atoms. The probe light is captured using a photodetector. The self-generated probe optical sidebands interfere to produce a beat note whose frequency is proportional to the magnetic field gradient between the two sets of atoms. Measuring the frequency of the beat note therefore provides an accurate reading of the magnetic field gradient. An optical filter or a polarizer can be additionally used to remove the central frequency of the probe light, thus removing the noise produced by the residual probe beam.

摘要： Various embodiments are described herein for an apparatus and a method for measuring and characterizing geometric distortions for a region of interest in images obtained using magnetic resonance. The method comprises deriving a computed set of 3D distortion vectors for a set of points within a region of interest covered by a phantom by using harmonic analysis to solve an associated boundary value problem based on boundary conditions derived from a measured set of 3D distortion vectors. The characterized image distortions may be used for various purposes such as for image correction or for shimming, for example.

摘要： Some implementations provide a method for safe operation of a magnetic resonance imaging (MRI) system, the method including: determining, at least in part by using a sensor device, location information that indicates a location of an MR-incompatible object relative to the MRI system, the MRI system generating a polarizing magnetic field for imaging a subject; based on the determined location information, determining, by a control unit associated with the MRI system, that the MR-incompatible object poses an operational hazard to the MRI system; and in response to determining that the MR-incompatible object poses an operational hazard to the MRI system, reducing, by the control unit, a strength of the polarizing magnetic field.

摘要： A jacket for radio frequency (RF) shielding a Magnetic Resonance Device (MRD) from external environment electromagnetic interference during its operation, which allows for homogenized imaging conditions. The RF shielding jacket is sized and shaped like an envelope to accommodate the MRD, with at least a portion of the RF shielding jacket including an electromagnetic interference shield. The RF shielding jacket is also combined with passive temperature insulating properties.

摘要： A magnetic resonance system is disclosed. The system includes a transceiver having a multichannel receiver and a multichannel transmitter, where each channel of the transmitter is configured for independent selection of frequency, phase, time, space, and magnitude, and each channel of the receiver is configured for independent selection of space, time, frequency, phase and gain. The system also includes a magnetic resonance coil having a plurality of current elements, with each element coupled in one to one relation with a channel of the receiver and a channel of the transmitter. The system further includes a processor coupled to the transceiver, such that the processor is configured to execute instructions to control a current in each element and to perform a non-linear algorithm to shim the coil.

摘要： Magnetic resonance imaging (MRI) acquisition and reconstruction techniques that invert MR signals of selected frequencies without the application of inversion RF pulses are disclosed. An example method comprises acquisition of at least one MR image representative dataset and an associated phase reference dataset, and classifies anatomical material into a first component representing anatomical material having a first range of resonance frequencies associated with a first range of phase differences between the MR image representative dataset and the reference image dataset and a second component representing anatomical material having a second range of resonance frequencies associated with a second range of phase differences between the MR image representative dataset and the reference image dataset. The method assigns different visual attributes to first and second components derived using phase differences between the MR image representative dataset and the reference image dataset and displays an image.
