TABLE I.

Ultrasound Treatment Parameters for Each Treatment Location or Each lesion.

Each treatment location			Each lesion (volume ~0.5 cm³)		Sample size
# of pulses	Treatment time (s)	Delivered energy (J)^*	Total treatment time	Total delivered energy (J)^**	Sample size
0	0	0	0	0	9
100	1	0.8	27 s	20.7	6
300	3	2.3	1.4 min	62.0	6
500	5	3.8	2.3 min	103.3	6
700	7	5.4	3.2 min	144.7	6
1000	10	7.7	4.5 min	206.7	9
1500	15	11.5	6.8 min	310.0	7
2000	20	15.3	9 min	413.4	6

The delivered energy per treatment location is calculated as I_SATA × A_BCS × T where A_BCS is the −6 dB beam cross-sectional area measured in free field, and T is the treatment time per treatment location.

^**

The total delivered energy for each lesion is calculated as (Delivered energy to each treatment location) × (Total number of treatment locations).
