“…As a result, some physical constraints must be considered when designing a HIFU array for prostate treatment. The array is usually integrated with a cylindrical housing, which must have a diameter of 2.2 cm or less; this means that the designed array must have a width of 2.2 cm or less [14].…”

“…The parameters of these arrays (frequency, maximum steering angle, maximum depth of penetration (DOP), element size, total array size, and total number of elements) were chosen according to some trial and error simulation (i.e., optimization studies were not performed). Among the few studies that have looked into optimizing ultrasound array design parameters, these studies either do not apply for the case of the prostate [7], or do not take into account all the parameters involved [14]. This paper describes model calculations for the optimization of focused 2-D ultrasound phased arrays for treatment of prostate cancer and BPH, including physical parameters such as frequency, array size, penetration depth, steering angle, and Grating lobe effects.…”

“…The defined small tissue volume wh ich is destroyed by one single ultrasonic beam is a "primary" lesion. In order to coagulate larger areas, mu ltip le lesions have to be added in a certain algorith m. Th is can be achieved by mechanically moving the energy source or electronically with a "phased array" [12][13][14][15][16].…”

“…With FUS, tissue is non-invasively necrosed by elevating the temperature at the focal point above 60 C using short sonications (10-30 s) and deep FUS has been reported to successfully ablate prostate tissue without inducing damage to the rectal wall [2][3][4][5] . The goal of prostate ablation is mainly to remove a non-desirable growth of the prostate.…”
