Hi all,<br><br>Anyone has used planePhantomUSCalibrationEstimation in Ultrasound Calibration Framework for the Image-Guided Surgery Toolkit to calibrate your US probe?<br><br>I run a test data for my US probe. The transform is gained by NDI Polaris device. The sum of squares is large and the image scale is obviously incorrect.<br>
