Doppler Panel

The Doppler Panel must be used to Calibrate the Doppler Flow and to set the Doppler Flow ROI.

The switch (1) enables and disables the Doppler Flow analysis.

Calibration

The Set Doppler X-Calibration button is used to Calibrate the x-axis of the Doppler Flow.

The drop down menu (2) shows the length of the line used for the calibration.

The numeric display (3) shows the x-calibration value.

The Set Doppler Y-Calibration button is used to Calibrate the y-axis of the Doppler Flow.

The drop down menu (4) shows the length of the line used for the calibration.

The numeric display (5) shows the y-calibration value.

ROI

The Set Doppler Flow ROI button is used to set the Doppler Flow ROI.

The numeric display (6) shows the top-left position, in pixels, of the Doppler Flow ROI (top-left corner).

The numeric display (7) shows the size (width x height), in pixels, of the Doppler Flow ROI.

The analysis of the negative value is enabled by checking the "Compute negative values" (8) tick box.

The sensitivity of the Doppler Flow analysis algorithm is set by the slider (9).

Once you have calibrated the B-Mode image and set the Diameter ROI, click on the Next button to proceed.
