Methods for acquiring ultrasonic data are disclosed. An image-acquiring system is provided. A three-dimensional target region is selected. A plurality of fiducial positions corresponding to anatomical features in the target region are calculated. A model of the target region comprising a plurality of target locations representing a plurality of planned locations in the target region at which ultrasonic data is to be acquired is created, and a visual representation of the model comprising a plurality of graphical elements is displayed. Ultrasonic data at each of the planned locations is acquired. A transformation of the visual representation is executed, comprising: performing a data quality test at each target location; for any target location that fails the data quality test, altering a graphical element corresponding to the failed target location to indicate failure of the data quality test at that location; and displaying a transformed visual representation comprising updated graphical elements on the visual display.
