WebHigh intensity focused ultrasound (HIFU) is a cancer treatment. It aims to kill cancer cells with high frequency sound waves. HIFU doesn't pass through solid bone or air, so it's not suitable for every cancer. You might have HIFU as part of a clinical trial for prostate cancer. Researchers are also looking at HIFU for some other types of cancer ... WebThe basic components of a sound wave are frequency, wavelength and amplitude. Frequency is the number of pressure waves that pass by a reference point per unit time and is measured in Hertz (Hz) or cycles per second.
