Abstract: Accelerated GRASE with controlled T2 blurring improves a point spread function (PSF) and temporal signal-to-noise ratio (tSNR) with many slices. The approach seeks to minimize a trade-off between SNR and blurring for functional sensitivity, and uses a new GRASE-optimized random encoding, which takes into accounts for the complex signal decays of T2 and T2* weightings, by achieving incoherent aliasing for constrained reconstruction. Numerical and experimental studies validate the effectiveness of the new method over regular and VFA GRASE (R- and V-GRASE).

Abstract: A method and apparatus for receiving (RX) radio-frequency (RF) signals suitable for MRI and/or MRS from MRI “coil loops” (antennae) that are overlapped and/or concentric, and each of which has a preamplifier and frequency-tuning circuitry and an impedance-matching circuitry, but wherein the loops optionally sized differently and/or located at different elevations (distances from the patient's tissue) in order to extract signal from otherwise cross-coupled coil loops and to improve signal-to-noise ratio (SNR) in images made from the received signal.

Abstract: An MRI method and an MRI system that simultaneously detect blood and/or CSF velocity or flow in plural slices or slabs preferably as not spatially adjacent. Two or more sets of interleaved slices or slabs can be assembled to cover the desired volume and derive higher quality MRI signals and images without a need for a contrast agent, even where the volume is too large for effective flow imaging with known techniques without contrast agent.

Abstract: Disclosed is a juicer device. In some aspects, the juicer includes a feed housing releasably connected about a rotatable cutter, and an input chute of the feed housing can be offset away from a side of the cutter that rotates upward. In some aspects, the juicer includes a feed housing releasably connectable by a rotation of the feed housing relative to the mount from an aligned position to an installed position so that the feed housing is locked in place in response to the rotating motion. In some aspects, the juicer includes a press chamber in which pulp can be squeezed for juice extraction. The press chamber can include a base and a wall, and a press chamber form can include a continuous piece of material forming at least a portion of the base, at least a portion of the wall, and a transition between the base and the wall.

Abstract: An MRI scanner and an MRI method that effectively reduce the inherent difference in timing of TE in the SIR images by using alternating polarity of the slice selective gradient pulse Gs and corresponding alternate polarity in RF phase offset in the excitation pulse. By using alternating polarity selective gradients, the refocusing gradient pulse on the Gs axis can be eliminated between the excitation pulses so that the time spacing between the multiple SIR excitation pulses is reduced, and therefore the time delay between onset of slice signal decay is reduced. This results in an earlier possible TE of the first excited slice, hence less signal decay and higher SNR, and overall the TE of different slices can be more nearly the same.

Abstract: An MRI system and method for dynamic susceptibility contrast (DSC) imaging use multiplexed echo planar imaging (M-EPI) to essentially simultaneously acquire MR signals for perfusion parameter images of multiple slices. This essentially simultaneous acquisition of MR signals for multiple slices can be repeated in rapid succession without deteriorating T2* contrast, which makes it practical to image multiple perfusion phases and brings about other significant benefits.

Abstract: Disclosed are methods and systems for carrying out super-multiplexed magnetic resonance imaging that entwines techniques previously used individually and independently of each other in Simultaneous Echo (or Imaging) Refocusing (SER or SIR) and Multi-Band (MB) excitation, in a single pulse sequence that provides a multiplication rather than summation of desirable effects while suppressing undesirable effects of each of the techniques that previously were used independently.

Abstract: An MRI system and method for imaging perfusion in an arterial spin labeled (ASL) process in which multiplexed echo-planar imaging (M-EPI) is used rather than conventional EPI, to thereby speed up imaging and generate sets of images that show different phases of perfusion and provide additional benefits. A single multiband RF excitation pulse can be used to excite multiple slices for imaging, or a time sequence of multiband pulses can be used to further increase the number of slices.

Abstract: Regional arterial spin labeling (regASL) speeds up acquisition without sacrificing the signal-to-noise ratio (SNR) of the resulting perfusion images by using the same control image (i.e. acquired without labeling of blood in a vessel) for two or more vascular territory measurements. This regional ASL is accomplished by creating prepared spin magnetization (e.g. inverted or saturated) in a specific blood vessel, instead of preparing spin magnetization in all feeding blood vessels. As in conventional ASL, two data sets are typically acquired in a downstream position: one with (label image) and one without preparation (control image) in one particular vessel.

Abstract: A process and system acquiring both ultrasound and MRI data from a patient in an MRI scanner and using one to automatically guide or improve the other. The ultrasound data can track the motion of an organ such as a cardiac artery or the diaphragm and the resulting motion information can automatically guide MRI data acquisition to keep the imaging volume at the organ or interest, or can be used to accept or reject MRI data in the process of forming an MRI image, based on whether the organ of interest was within an acceptable range of positions. Conversely, the MRI unit can guide the ultrasound data acquisition so it is properly timed or otherwise controlled in accordance with MRI data acquisition.
