Abstract:
1. A method for reducing reflection and tissue heating in a high intensity focused ultrasound (HIFU) procedure, comprising the steps of: identifying a location of a patient at which HIFU, administered at a HIFU focus, encounters a tissue/air interface in a propagation direction after said HIFU focus; covering said location, immediately adjacent said tissue/air interface, with a first layer of ultrasonic coupling gel, said first layer consisting of substantially bubble-free ultrasonic coupling gel; covering said location with a second layer of ultrasonic coupling gel, overlying said first layer of ultrasonic coupling gel at a side of said first layer of ultrasonic coupling gel opposite said tissue/air interface, said second layer consisting of foamed ultrasonic coupling gel.
