摘要： Apparatus, methods, and other embodiments associated with magnetic resonance imaging (MRI) blipped trajectories having varying blip amplitudes are described. One example method includes controlling an MRI apparatus to produce a set of blipped trajectories including a first blipped trajectory having a first blip amplitude and a second, different blipped trajectory having a second, different blip amplitude. The blip amplitudes may be based on a relationship between a trajectory and a reference. The relationship may be, for example, a rotation angle. The rotation angle may be a proxy for information including a gradient trajectory speed associated with a blipped trajectory or an amount of unused gradient energy available while producing the blipped trajectory. The blip amplitudes may be selected to produce incoherent sampling during an MRI acquisition that uses the blipped trajectories. In one example, readout directions may be altered between trajectories to reduce regularity in k-space.

摘要： A system and method to perform parallel MR imaging are disclosed. The system comprises an MR imaging machine and a probe having at least two MR RF reception coils. Each coil of the probe is operationally connected to a separate receiver channel of the MR imaging machine. The MR imaging machine implements a partially parallel acquisition method to excite precessing nuclear spins, in and around an internal segment of a patient into which the probe is inserted, and to use the coils of the catheter to simultaneously sample a plurality of response signals to form reduced k-space data sets for each of the coils. The plurality of response signals represent nuclear magnetic resonance signals arising from the precessing nuclear spins. The reduced k-space data sets are further processed by the MR imaging machine to generate a full volume dataset of a region in and around the vessel.

摘要： Apparatus, methods, and other embodiments associated with multi-slice blipped TrueFISP-CAIPIRINHA in magnetic resonance imaging (MRI) are described. One example apparatus produces CAIPIRINHA phase cycling in a TrueFISP-CAIPRINHA pulse sequence using a blipped gradient pattern rather than using radio frequency (RF) pulses. The phase cycling is produced by controlling a gradient coil in an MRI apparatus to produce a pre-scan pulse that is configured to set magnetization into a steady state position and then controlling the gradient coil to produce a balanced alternating phase pulse per repetition (TR). The balanced alternating phase pulse is configured to introduce a CAIPIRINHA aliasing pattern between slices. Controlling the gradient coil includes selectively adding and removing a finite gradient area from de-phase pulses and re-phase pulses in the pulse sequence.

摘要： Example apparatus and methods order projections in a 3D MRI acquisition to achieve improved equidistant spacing or to achieve improved adherence to a target distribution. The equidistant or target spacing may exist in k-space and/or in kt-space. In one embodiment, the improved equidistant spacing is a substantially uniform spacing. The substantially uniform spacing may be achieved using a modification of a charge repulsion analysis that treats points of projections that intersect the surface of a 3D volume to be imaged as point charges distributed on the 3D volume. In another embodiment, the target spacing may be uniform, non-uniform, uniform in parts and non-uniform in other parts, and other combinations.

摘要： Systems and methods of writing data to a buffer during a buffer cycle are described. The buffer has a plurality of buffer banks having various fill levels. The buffer determines a first portion of banks from the plurality of buffer banks. The first portion of banks unfilled banks. A rank can be assigned to each of the first portion of banks and a candidate set of banks chosen from the first portion of banks. A target bank is then chosen from the candidate set and the data is written to that bank. The ranking may be random. Furthermore, the target bank can be chosen based on ranking, fill level, or both.

摘要： In a method and apparatus for generating a magnetic resonance image of a contiguous region of a human body on the basis of partial parallel acquisition (PPA) by excitation of nuclear spins and measurement of radio-frequency signals indicating the excited spins, the spin excitation is implemented in steps with measurement of an RF response signal simultaneously in each of a number of N component coils. a number of response signals thus are acquired that, for each component coil, form an incomplete data set (40) of acquired RF signals. Additional acquired calibration data points exist for each incomplete data set. The N incomplete data sets are acquired to a subset of M reduced, incomplete data sets on the basis of an N×M reduction matrix, so that M reduced, incomplete data sets are obtained, M complete data sets are formed on the basis of an N×M reconstruction matrix with the non-measured lines of the M reduced, incomplete data sets being reconstructed from all N incomplete data sets. A spatial transformation of the completed reduced data sets is then implemented in order to form a complete image data set from each completed, reduced data set.
