SarRatio

class pulserver.ir.SarRatio

Bases: object

A subsequence’s RF energy per pulse, against the reference pulse at the head SAR limit.

Each is the largest over the subsequence’s repetitions, per pulse the repetition plays, at the drive scale where the reference pulse meets the head SAR limit. local_sar is the repetition’s peak local energy, through the VOPs and times the VOP file’s safety factor, over the reference pulse’s head energy in the body model where it is smallest, times the head limit over the local limit. global_sar is the repetition’s head energy over the reference pulse’s, body model by body model. Given the time the scanner gives the reference pulse, times the larger of the two, each pulse of the subsequence stays within both limits. Both are 0 without RF.
