Применяемые в медицине технологии воздействия сфокусированным ультразвуком достаточно часто имеют высокий уровень артефактов при визуализации диагностических исследований и осложнений при проведении терапии. При моделировании воздействия сфокусированным ультразвуком применяемые решатели должны учитывать распространение волны давления, изменения и скачки плотности, нелинейность и потери диффузии, которые происходят в тканях человека, и предлагать моделирование акустического распространения в неоднородных установках практически в реальном времени. В статье представлены результаты мультифизического и математического моделирования в пакете Sim4Life for Science V7.0 с применением полноволнового акустического решателя (P-ACOUSTICS) современной вычислительной акустики.</title></sec></abstract><trans-abstract xml:lang="en"><sec><title>To study tissue permeability under extracorporeal exposure to various types of radiation, it is necessary to use multiphysical and mathematical modeling of all stages of the technology being developed, taking into account the dielectric and acoustic properties of human body tissues. The technologies used in medicine with focused ultrasound often have a high level of artifacts in the visualization of diagnostic studies and complications during therapy. When modeling exposure to focused ultrasound, the applied solvers must take into account pressure wave propagation, density changes and jumps, non-linearity and diffusion losses that occur in human tissues, and offer simulation of acoustic propagation in inhomogeneous installations in near real time. The article presents the results of multiphysics and mathematical modeling in the Sim4Life for Science V7.0 package using a full-wave acoustic solver (P-ACOUSTICS) of modern computational acoustics.</title></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>биологический образец</kwd><kwd>моделирование</kwd><kwd>ультразвук</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biological sample</kwd><kwd>modeling</kwd><kwd>ultrasound</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kamlach P.V., Grodo D.S., Churakov A.V., Kamlach V.I., Bondarik V.M., Madveiko S.I., Klyuev A.P.
