Resumo

Thermal ablation rates and the shapes of volumetric biological tissue lesion are compared in a numerical experiment, in which biological tissue is exposed to pulsed periodic shock-wave high intensity focused ultrasound. The comparison is performed across three different irradiation sequences of discrete foci placed uniformly within the target area.

Pressure profiles at the focus (left column), spatial distributions of the power density of thermal sources in the tissue (middle column) and temperature distributions (right column) at the moment of focus movement (20 ms) in the axial xz planes of the beam for (a) the saturation mode (I0 = 15 W/cm2) and (b) the mode with the formation of a developed rupture (I0 = 8 W/cm2). The black contour indicates the region of thermal destruction.

4. Fig. 3. Spatial temperature distributions at the end of tissue irradiation along a trajectory with different focus switching sequences: “clinical” (a, d), “spiral” (b, d), “snake” (c, e) for the modes I0 = 8 W/cm2 (left column, a–c) and I0 = 15 W/cm2 (right column, d–e). The black contour indicates the region within which the thermal dose exceeded its threshold value after the sample cooled. The end time of heating, the achieved size of thermal destruction, and the thermal ablation rate are shown on each spatial temperature distribution.
