This study analyzes the + effects of scanning path, applied power, and geometric characteristics of the + transducer on ablation using fast scanning method, a new scanning method that + uses high-intensity focused ultrasound at different blood perfusion levels. + METHODS: Two transducers, six scanning paths, and three focal patterns were used + to examine the ablation results of the fast scanning method using power densities + from 1.35 x 10(7) Wm(3) to 4.5 x 10(7) Wm(3) and blood perfusion rates from 2 x + 10(-3) mlmls to 16 x 10(-3) mlmls. The Pennes equation was solved using the + finite-difference time-domain method to simulate the heating procedure. RESULTS: + Based on the results of the fast-scanning method, the different scanning paths + exhibited small effect on the total treatment time supported by both simulation + and least-square fit. Similar-sized lesions can result from the five different + repeated paths, whereas a random path may lead to relative large fluctuations in + ablation volume because of asymmetry of the lesions. Higher power levels increase + the lesion volume and decrease the treatment time required for ablating a target + area using the fast scanning method, whereas increased blood perfusion has the + opposite effect on ablation volume and treatment time. A symmetric lesion can be + produced through fast scanning method using a 65-element and a 90-element + transducer. However, lesion production using the same operation scheme differs + between the two transducers. CONCLUSIONS: Unlike traditional scanning methods, + fast scanning method produces a planned lesion regardless of scanning path, as + long as the path consists of repeated subsequences. This attribute makes fast + scanning method an easy-operation scheme that produces relatively large symmetric + lesions in homogeneous tissues. Applied power is the most important factor; + however, high blood perfusion levels can limit or even hinder the full ablation + of the target area. Therefore, tissue perfusion and transducer type should be + given special attention to ensure the success and safety of ablation treatment. +FAU - Qiao, Shan +AU - Qiao S +AD - School of Biomedical Engineering, Shanghai Jiao Tong University, Shanghai, + People's Republic of China. +FAU - Shen, Guofeng +AU - Shen G +FAU - Bai, Jingfeng +AU - Bai J +FAU - Chen, Yazhu +AU - Chen Y +LA - eng +PT - Journal Article +PT - Research Support, Non-U.S. Gov't +PL - United States +TA - Med Phys +JT - Medical physics +JID - 0425746 +SB - IM +MH - Blood Circulation +MH - High-Intensity Focused Ultrasound Ablation/adverse + effects/instrumentation/*methods +MH - Humans +MH - Models, Biological +MH - Sonication +MH - Temperature +MH - Time Factors +MH - Transducers +EDAT- 2012/10/09 06:00 +MHDA- 2012/12/10 06:00 +CRDT- 2012/10/09 06:00 +AID - 10.1118/1.4748329 [doi] +PST - ppublish +SO - Med Phys. 2012 Oct;39(10):5795-813. doi: 10.1118/1.4748329.
