Хотя первые попытки использования hifu в медицине были сделаны в США в начале 1940-х гг., история применения мощного фокусированного ультразвука для локального воздействия на глубокие структуры ... WebHigh-intensity focused ultrasound (HIFU) uses ultrasonic energy in the frequency range of 20 kHz–200 MHz to create focused thermal ablation lesions by molecular vibration and friction, without affecting intervening structures ( Fig. 123.5). HIFU energy delivered circumferentially via a balloon at the PV ostium was developed for PV isolation.
