Abstract :
Recent development of magnetic resonance (MR) imaging equipment enables interventional radiology (IVR) as diagnosis and treatment under MRI usage. In this paper, a new methodology for MR scanner to apply not only as diagnostic equipment but as for treatment one is discussed. The temperature measuring procedure for MR is to measure phase shift of T1 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 a temperature measuring equipment and as a heating equipment for applying such as hyperthermia heating modality.
