Quantification
Quantitative Ventricular Analysis (LVA)
74 / 104 AXA4-100.620.08.01.02 Operator Manual
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.
“Permitted rotation range” on page 102
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.
