Abstract:
Phase-Controled high intensity focused ultrasound 3D temperature distribution is the key indicator for measuring the efficiency of HIFU transducer. Considerable progress has been achieved in the use of infrared (IR) imaging techniques for qualitative mapping of acoustic and thermal field of high intensity focused ultrasound (HIFU) transducers. This article proposes a method to measure phased-controled characteristics of HIFU based on infrared thermal imaging and establishes a whole measurement system to make the method more quantitative and reliable. The result shows that the proposed measurement system is able to measure pHIFU characteristics rapidly and precisely, which wil be of great significance in standardizing the measurement of pHIFU acoustic field.
