English to German Medical Livestock / Animal Husbandry Ultraschallscans

Still the same software strings, but now these are tips for how to conduct the examination:
Detect the objective for the fan scan and sliding scan.
Another example:
Use the slide scan and fan-shaped scan together to observe all livers.
I take it these are two different types of scans - is Fan-Scan acceptable in German? I couldn't find anything that would indicate it is, but I couldn't find anything else, either. Fächerförmig scannen?

Vielen Dank für Eure Hilfe, wie immer!
