Abstract: A system comprises presentation of a user interface on the display for inputting a first set of parameter values for a magnetic resonance scan, reception of the first set of parameter values for the magnetic resonance scan from a user via the displayed user interface, and automatic determination, based on the first set of parameter values, of first additional parameter values for the magnetic resonance scan.

Abstract: A system for generating medical image scanner configurations includes a scanner configuration database and a simulation component. The database stores a scanner configuration dataset corresponding to a medical image scanner. The simulation component includes a display module which is configured to present a graphical user interface (GUI) utilized by the medical image scanner, and an editing module which is configured to create a modified scanner configuration dataset based on commands received from a user via the GUI. Additionally, the simulation component includes a simulation module which is configured to (i) perform a simulation of the medical image scanner using the modified scanner configuration dataset to yield simulated results, (ii) use the display module to present the simulated results in the GUI, and (iii) in response to receiving user approval of the simulated results via the GUI, save the modified scanner configuration dataset to the database.

Abstract: A magnetic resonance method and system are provided for providing improved multi-band (MB) magnetic resonance imaging. The adaptive MB imaging can be achieved by providing one or more modified multi-band excitation pulse sequences that include at least either one nullified “dummy” slice within a slab that is not excited simultaneously with the other slices during a single multislice acquisition sequence, or one excitation slice group that utilizes a non-uniform slice spacing between simultaneously excited slices. Adaptive GRAPPA or slice-GRAPPA kernel sizes can also be used during image reconstruction to improve speed without excessive point spread blurring or MB reconstruction failure. A total leakage factor (TLF) can also be determined based on test images using modified MB excitation sequences, and used to improve the adaptive MB procedure.

Abstract: A system uses multiple RF coils in MR imaging and an RF (Radio Frequency) signal generator generates RF excitation pulses in anatomical regions of interest and enables subsequent acquisition of associated RF echo data. A magnetic field gradient generator generates anatomical volume select magnetic field gradients for phase encoding and readout RF data acquisition. The RF signal generator and the gradient generator substantially concurrently acquire first and second volumes of first and second different anatomical regions by providing, a first RF pulse having a first asymmetric shape followed by a successive second RF pulse substantially having the first asymmetric shape but reversed in time, to substantially reduce echo time (TE) differences between acquisition of the first and second volumes and a phase encoding magnetic field gradient prepares for acquisition of data representing the first and second volumes.
