Multi-slice Blipped TrueFISP-CAIPIRINHA

An apparatus configured to control an RI apparatus to produce a multi-slice blipped TrueFISP-CAIPIRINHA pulse sequence, the apparatus comprising:

• a first logic configured to add a finite gradient area to a first de-phase pulse produced by a slice select gradient during a first TR in the TrueFISP CAIPIRINHA pulse sequence;
• a second logic configured to add the finite gradient area to a first re-phase pulse produced by the slice select gradient during the first TR in the TrueFISP CAIPIRINHA pulse sequence;
• a third logic configured to remove the finite gradient area from a second de-phase pulse produced by the slice select gradient during a second TR in the TrueFISP-CAIPIRINHA pulse sequence,
• a fourth logic configured to remove the finite gradient area from a second re-phase pulse produced by the slice select gradient during the second TR in the TrueFISP-CAIPIRINHA pulse sequence, and
• a control logic configured to control the first logic, the second logic, the third logic, and the fourth logic to introduce CAIPIRINHA phase shift cycling for members of the multiple slices processed by the multi-slice blipped TrueFISP-CAIPIRINHA pulse sequence by selectively adding and removing the finite gradient area from de-phase pulses and re-phase pulses in different TRs.
