Perform Calculations and Save Them to the Worksheet

In the Calculations panel, you can generate calculations and save the values to the study's Worksheet.

To perform a calculation,

1. Click the Calculations button to open the Calculations panel.
2. Then, click the + button to add a calculation.
3. Select the type of calculation you want to add.

• For each measurement requested, you can either use the Draw tool to define the measurement or the Select tool to choose a measurement you've already drawn.
• To identify a field on the Worksheet for a calculation, click the name of the calculation and select from the drop-down list.

The indicator changes color depending on the status of the value:

• Blue: No value has been calculated yet.
• Orange: The value has been calculated, but no field on the Worksheet has been selected for it.
• Yellow: The value has been calculated, and a field on the Worksheet has been selected for it. To save the value to the worksheet, click the indicator when it is yellow.
• Green: The value has been saved to the selected field on the Worksheet.

Click the hamburger menu to the right of each calculation to display a list of options, which include

• Hide info / Show info
• Show this calculation only / Show all calculations
• Save value to worksheet
• Delete calculation

To save all values in the Calculations panel to the Worksheet at once, click the Save All button at the bottom of the Calculations panel.

Once you have saved a value to a specific field on the Worksheet, you cannot save a second value to that same field. Before you can save a new value to that field on the Worksheet, you will need to delete the value currently associated with that field in the Calculations Panel.

If the study's worksheet is open when you save measurements and calculations to the worksheet, you will need to refresh the worksheet to see the values. To do that, click your browser's Refresh button.

For images that meet certain technical requirements, the following calculations are available and can be saved to the Worksheet.

• Velocity (VEL)
• Pressure Gradient (PG)
• Pressure Half Time (PHT)
• Velocity Time Integral (VTI)
• Ejection Fraction (EF)
