Good quality and timely feedback supercharges learning 10x but is difficult to find.

Find a supervisor who will watch over your shoulder while you scan and give you tips on improving and optimizing your image.

Learn how to save, store or print images. Show these to an expert later and get their feedback. Carry around a USB thumb drive for this purpose but remember to respect patient privacy.

Carry around a notebook and note the names of the patients you scan then check back later after they have had their formal ultrasound or echo study and compare your findings.
