 Operating Procedures
1. Enter color mode, adjust the color map until the aliasing appears.
2. Select [PISA MR] in the measurement menu.
3. Measure MR Rad using PISA caliper.
Input MR Als.Vel.
4. Measure the MR spectrum by D trace to obtain:
MR Vmax
MR VTI
MR Flow, MR Flow Rate and MR EROAare calculated automatically.
If MV SV is measured, MR Fraction will be calculated automatically.
PISA AR
Aortic valve regurgitation (PISA AR) needs to be measured in Color and Doppler mode.
