Real-time and non-invasive temperature monitoring of thermotherapy using MRI / 生物医学工程学杂志

ABSTRACT

High-intensity focused ultrasound (HIFU) thermotherapy is a promising technique for local tumor destruction of solid organs. Temperature is the important parameter which impacts the curative effects of thermotherapy. For safety and efficiency reasons, it is necessary to monitor the temperature changes inside body in real-time, non-invasively and precisely. Recently MRI methods employed for temperature monitoring during HIFU therapy have been paid more and more attentions to. This paper introduces the general principles of non-invasive temperature monitoring using MRI. The authors also review the development of this technique and point out some problems that need to be solved.
