3.4 Cardiac scan modes

Cardiac Axial
Use Cardiac Axial imaging for low dose cardiac or cardiovascular imaging when the system
data acquisition timing will use the patient's ECG signal.
Cardiac Axial imaging can acquire data at one or multiple cardiac phases or phase ranges
within a single cardiac cycle.
Cardiac Axial imaging can be used to simultaneously acquire images of cardiac function by
imaging at a low dose throughout one complete cardiac cycle.
Cardiac Axial imaging can be used to obtain images during consecutive cardiac cycles.
Cardiac Axial imaging with AutoGating uses a patient's heart rate and heart rate variation to
determine the patient-specific cardiac scan duration, providing robust acquisition of the
cardiac phases that will be most useful for clinical assessment.
Cardiac Axial imaging incorporates automatic adjustment of the system collimation to
acquire low dose cardiac scans within a single heartbeat, and to acquire larger scan ranges
with automated, dose-optimized collimation with a minimum number of interscan table
position boundaries.
