Summary table of focused ultrasound parameters [104].

Parameter	Unit	Definition
Frequency	MHz, Hz	Number of cycles or oscillations per second
Pressure	MPa	Pressure caused by a sound wave minus the ambient pressure in a medium resulting from the sound wave
Pulse repetition frequency	Hz	Number of emitted pulses that occur per second
Burst duration	ms	The length of time designated for repeat pulses at a constant frequency
Total exposure time/total time (TT)	s	The total amount of time the transducer is emitting ultrasonic energy in an area
