In focused ultrasound surgery, high intensity focused ultrasound (HIFU) can be used to destroy pathological tissue deep inside the body without any damage to the surrounding normal tissue. This noninvasive technique has been used to treat malignant tumors of the liver, prostate, kidney, and benign breast tumors via a percutaneous or transrectal approach without the need for general anaesthesia. In the present study, a finite element method was used for the simulation of temperature elevation in soft tissue by HIFU. First, the HIFU field was modeled using the Westervelt equation for the propagation of finite-amplitude sound in a thermoviscous fluid in order to account for the effects of diffraction, absorption, and nonlinearity. Second, the Pennes bioheat transfer equation was used to predict the temperature elevation in soft tissue by HIFU. In order to verify the numerical simulation, the simulated temperature elevation at the focus in a tissue-mimicking phantom was compared with the measurements, using a concave focused transducer with a focal length of 62.6 mm, a radius of 35.0 mm, and a center frequency of 1.1 MHz.

Abstract Objective To evaluate a naturally derived acellular dermal scaffold for soft tissue reconstruction using high-intensity focused ultrasound energy (HIFU). Materials and Methods Acellular dermal scaffolds (ADSs) were prepared by purification of bovine skin. Half of the scaffolds were subjected to high-intensity focused ultrasound energy (HIFU) to modify collagen structure, whereas the other half was used as control. A large skin defect was made in the dorsum of white mice, and the scaffolds were used to cover the induced defects. Wound healing was evaluated histologically after 2, 6, and 12 weeks using common and specific stained sections (n = 20). Statistical Analysis Mean values and standard deviations were calculated for each group, and Student’s t-test was used for statistical analysis (α= 0.05; n = 20). Results After 2 weeks, all examined specimens revealed the presence of inflammatory cellular infiltration and early immature blood vessel formation. After 6 weeks, inflammatory cellular infiltration was reduced, with evidence of maturation of new blood vessels observed for all groups. After 12 weeks, there was a significant increase (F = 124, p < 0.01) in new collagen formation and count of mature blood vessels observed for the HIFU group compared with control. Evidence of remodeling of new collagen fibers and biodegradation of the grafts was also observed. Conclusions HIFU-modified ADSs enhanced wound healing and could be used to cover large soft tissue defects.
