Quantitative Ventricular Analysis (LVA)

Calibration
Before you can perform quantitative ventricular analysis, you must calibrate the
scene.
We recommend performing analysis with sphere calibration. This provides the
best results.
➩ Chapter Calibration
Selecting the analysis method
Make sure that the calibration object and the ventricle have the same geometric
acquisition parameters, that is,
o the same focus-to-object and object-to-I.I./FD distances
o the same I.I./FD size
o the same stand positions
o the same image matrix
Otherwise the results will be less reliable.
For calibration, use an object with almost the same size as the object to be mea-
sured.
Depending on the installation, some analysis methods may not be available to
you.
If the deviation from the 30° RAO projection is impermissibly large, it is not pos-
sible to select LVA.

Make sure that you have entered Height and Weight of the patient before you
start LVA. If not, the Index values will not be available.
