Abstract: A method of estimating gestational age (GA) is shown generally at 3000. At Step 3010 an ultrasound image is acquired. The image is fed into the model at Step 3020 and a predicted GA value, together with an associated confidence interval are calculated at Step 3030. At Step 3040 it is determined whether the confidence interval is narrower than a value for the best confidence interval obtained. If not, the ultrasound operation is optionally directed to acquire an ultrasound image of a particular plane in the fetus at Step 3050. On the other hand, if the value is determined to be narrower than the best obtained at Step 3040, the predicted value and confidence interval are displayed at Step 3060 and a register for the value of the best confidence interval is updated at Step 3070.

Abstract: The invention relates to a simulator training system for simulation training in ultrasound examination or ultrasound-guided procedures. The training system comprises a movable simulator input device to be operated by the user, and means for displaying an ultrasound scan view image which is an image or facsimile image of an ultrasound scan. The scan view image is variable and related to the position and/or orientation of the simulator input device. The system further includes means for displaying a second image, the second image being an anatomical graphical representation of a slice through of the body structure associated with the ultrasound scan view, the slice through displaying the scan beam plane of the simulator input device. The ultrasound scan view image and the second image are linked to vary in a coordinated manner as the position and/or orientation of the simulator input device changes.
