calc_rf_center

pypulseqpp.calc_rf_center()

Calculate the time point of the effective rotation calculated as the peak of the radio-frequency amplitude for the shaped pulses and the center of the pulse for the block pulses. Zero padding in the radio-frequency pulse is considered as a part of the shape. Delay field of the radio-frequency object is not taken into account.

Parameters:

rf (SimpleNamespace) – Radio-frequency pulse event.

Returns:

• time_center (float) – Time point of the center of the radio-frequency pulse.

• id_center (float) – Corresponding position of time_center in the radio-frequency pulse’s envelope.

Notes

This is PyPulseq’s function. Events go in as the namespaces it expects and come back with their fields in slots.
