Cardiac Gating

Cardiac gating involves timing imagee accuition with phases of the hearhearbet, typically using ECG signals. Ini sinkronisasi ization motioor blur revod by the hearbeot, reallting iclearer images.

Breath-Hold Technicques

Pasien are instructed to hold their breath durith imagine accuition, which minmizes respiatory motion. Shorter scaln timets and coaching improve the efectivenesso of this method.
