Detailed Description

This file sets up the global rfpulse[] struct array, used for RF scaling, with KS_MAXUNIQUERF (=20) number of empty RF_PULSE member slots, followed by including RF_PULSE struct from "rf_Prescan.h".

It is required that rfpulse[], rfpulseInfo[] arrays, and RF_FREE exist in the main sequence.

For GE's pulse sequences,

• rfpulse[] is declared in grad_rf_<seqname>.h
• RF_FREE is automatically set in rf_Prescan.h based on RF_FREE1 in grad_rf_<seqname>.globals.h
• rfpulseInfo[] is declared in @ipgexport for all GE sequences.

For pulse sequences written entirely using KSFoundation

• rfpulse[] is declared in this file
• RF_FREE is automatically set in rf_Prescan.h based on RF_FREE1 in grad_rf_empty.globals.h
• rfpulseInfo[] is declared in @ipgexport of GERequired.e
