Calibrate the B-Mode image

The calibration of the images must be done before starting a new examination because it is necessary to provide information about the size of the image generated by ultrasound system. The calibration factor changes depending on the settings of your ultrasound machine. You should check the calibration at each new examination.

CAUTION: the lack of calibration can generate a software malfunction.

Calibrate the B-Mode image

• Locate, in ultrasound image, a range of known distance (30 mm. in the example of figure).
• In the B-mode Panel, select from the drop-down menu, the distance specified above.
• In the B-mode Panel, click on the Set B-Mode Calibration button (button remains active).
• Draw a line on the image corresponding to the known distance: click on one end and drag the mouse to the other extreme (press the Shift key or Ctrl+Shift keys on your keyboard if you want the line to be not vertical or horizontal).

NOTE: you can directly type the calibration value in the "calib" field of the B-mode Panel (if you already known the value).
