An ultrasound imaging system (UIS) comprises a user interface (UIF) that allows an operator to request visual aid. In response to a request for visual aid, a controller (CTRL) retrieves from a database a visual representation of a preferred manner of applying a probe to a patient, and causes a display device (DPL) to render the visual representation. Preferably, but not necessarily, the controller (CTRL) detects a step of a workflow protocol program (WPP) that is being carried out. The controller (CTRL) then selects from the database a visual representation pertaining to the step that is being carried out.
