===SPINAL Decoupling===
SPINAL decoupling is an extension of TPPM. SPINAL can be thought of as TPPM with a supercycle. Like TPPM, the pulse width must be optimized once a decoupling amplitude has been set. The phases are generally set to 5, 10, and 15, however in this implementation the user has the option to change each phase as they see fit. The SPINAL supercycle is chosen through the spinal_flag variable. when the flag is zero, it is TPPM decoupling, 1=SPINAL8, 2=SPINAL16, 3=SPINAL32 and 4=SPINAL64. When alpha=beta=0 and phi(SPINAL) = 1/2 phi(TPPM) the result is also very near to TPPM decoupling.

SPINAL Decoupling

SPINAL decoupling is an extension of TPPM. SPINAL can be thought of as TPPM with a supercycle. Like TPPM, the pulse width must be optimized once a decoupling amplitude has been set. The phases are generally set to 5, 10, and 15, however in this implementation the user has the option to change each phase as they see fit. The SPINAL supercycle is chosen through the spinal_flag variable. when the flag is zero, it is TPPM decoupling, 1=SPINAL8, 2=SPINAL16, 3=SPINAL32 and 4=SPINAL64. When alpha=beta=0 and phi(SPINAL) = 1/2 phi(TPPM) the result is also very near to TPPM decoupling.
