The disclosure also provides methods for generating multi-dimensional images by using the imaging system. The disclosure also provides processes of applying a plurality of xSPEN readout gradient on the single-sided magnetic resonance imaging system disclosed herein.
Claims19
A single-sided magnetic resonance imaging system comprising:
- a housing comprising:
- a front surface;
- a permanent magnet for providing a static magnetic field that extends from the permanent magnet relative to a first axis into a region of interest, wherein the first axis is perpendicular to the permanent magnet;
- a radio frequency transmit coil;
- and
- a single-sided gradient coil set, wherein the radio frequency transmit coil and the single-sided gradient coil set are positioned proximate to the front surface;
- a radio frequency receive coil;
- a power source, wherein the power source is configured to flow current through at least one of the radio frequency transmit coil or the single-sided gradient coil set to generate an electromagnetic field in the region of interest, wherein at least a portion of the region of interest resides outside the front surface;
- and
- a control circuit configured to:
- transmit an excitation pulse with the radio frequency transmit coil;
- transmit a first refocusing pulse with the radio frequency transmit coil;
- apply a first xSPEN readout gradient, during the first refocusing pulse, along a second axis orthogonal to the first axis with the single-sided gradient coil set;
- perform phase encoding along a third axis orthogonal to the first axis and orthogonal to the second axis with the single-sided gradient coil set;
- transmit a second refocusing pulse with the radio frequency transmit coil;
- apply a second xSPEN readout gradient, during the second refocusing pulse, along the second axis with the single-sided gradient coil set;
- and
- receive data with the radio frequency receive coil.
