概要

• 論文の詳細を見る

• It is commonly accepted that the temperature elevation in biological specimens resulting from ultrasonic absorption will be the same for both continuous and pulsed ultrasound fields for identical spatial-peak, temporal-average intensities. The rate of heat generation per unit volume is typically determined by time average the square of the pressure waveform divided by ρc_0 over the pulse repetition frequency. The assumption that pulsed and continuous ultrasound fields produce the same temperature elevation for identical spatial-peak, temporal-average intensities is examined from an alternate perspective and is found be consistent with the above usual practice.
