Abstract
A system for performing arterial-spin labeling (“ASL”) includes at least one memory configured to store instructions and at least one processor configured to execute the instructions to cause the system to perform a labelling phase and a control phase. The labelling phase includes a first plurality of radio frequency (“RF”) pulses and each RF pulse of the first plurality of RF pulses has a frequency offset and a phase offset. The control phase includes a second plurality of RF pulses and each RF pulse of the second plurality of RF pulses has the frequency offset and the phase offset and alternating RF pulses of the second plurality of RF pulses has an additional phase shift.
Claims24
A system for performing arterial-spin labeling (“ASL”), the system comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to cause the system to
- perform a labelling phase, the labelling phase including a first plurality of radio frequency (“RF”) pulses, each RF pulse of the first plurality of RF pulses having a frequency offset and a phase offset, and
- perform a control phase, the control phase including a second plurality of RF pulses, each RF pulse of the second plurality of RF pulses having the frequency offset and the phase offset and alternating RF pulses of the second plurality of RF pulses having an additional phase shift.
A method for performing arterial-spin labeling (“ASL”), the method comprising:
- performing a labelling phase, the labelling phase including a first plurality of radio frequency (“RF”) pulses, each RF pulse of the first plurality of RF pulses having a frequency offset and a phase offset;
- and
- performing a control phase, the control phase including a second plurality of RF pulses, each RF pulse of the second plurality of RF pulses having the frequency offset and the phase offset and alternating RF pulses of the second plurality of RF pulses having an additional phase shift.
A non-transitory computer readable medium storing computer-executable instruction that, when executed by at least one processor of a system, cause the system to perform a method for performing arterial-spin labeling (“ASL”), the method comprising:
- performing a labelling phase, the labelling phase including a first plurality of radio frequency (“RF”) pulses, each RF pulse of the first plurality of RF pulses having a frequency offset and a phase offset;
- and
- performing a control phase, the control phase including a second plurality of RF pulses, each RF pulse of the second plurality of RF pulses having the frequency offset and the phase offset and alternating RF pulses of the second plurality of RF pulses having an additional a phase shift.
