To calculate Proximal Isovelocity Surface Area (PISA)
The PISA calculation requires a measurement in 2D, a measurement in Color, and two measurements in
Doppler spectral trace. After all measurements are saved, the result appears in the patient report.
1 Measure from Ann D:
a On a frozen 2D image, tap Calcs.
If this control is hidden, tapping More Controls displays it.
b On the PISA calculation list, tap Ann D.
c Position the calipers by dragging.
d Save the calculation: Tap
2 Measure from Radius:
a On a frozen Color image, tap Calcs.
b On the PISA calculation list, tap Radius.
c Position the calipers by dragging.
d Save the calculation: Tap
3 On a frozen Doppler spectral trace, tap Calcs.
4 Do the following to measure from MR VTI and again to measure from MV VTI:
a On the PISA calculation list, tap MR VTI or MV VTI.
b Drag the caliper to the start of the waveform, and lift your finger to start the trace.
A pencil icon appears.
c Using your finger, trace the waveform.
To make a correction, trace backward on the dotted line.
d Lift your finger to complete the trace.
