Abstract :
Recent development of Magnetic Resonance Imaging (MRI) equipment enables Interventional Radiology (IVR) as diagnosis and treatment under MRI usage. In this paper, a new methodology for Magnetic Resonance (MR) scanner to apply not only diagnostic equipment but for treatment one is discussed. The temperature measuring procedure under MR is to measure phase shift of T1, which is the longitudinal relaxation time of proton, for the position inside a sample material with the application of pulsed RF for heating inside the sample as artificial dielectrics. The result shows the possibility to apply MR as temperature measuring equipment and as a heating equipment for applying such as hyperthermia heating modality.
