C1CEFR level
60/100Rarity: rare
TechnicalRegister
The hand-held probe that both emits and receives sound waves during ultrasound.
A little more gel was applied so the transducer made good contact with the skin.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
