세미나 제목 : Magnetic Resonance Imaging (MRI) – based Electrical Property Retrievals

발표초록 :

To obtain an in vivo electrical property map of human body in a non-invasive way has been motivated by a numbers of reasons. First, electrical property of human tissue has high contrast, therefore an electrical property map provides anatomical information of human body. Secondly, electrical property can be used for early cancer detections because the electrical property of cancerous tissues is highly distinguishable from that of healthy ones. Moreover, an electrical property map is crucial for accurate calculation of specific absorption rate (SAR) which is a main parameter for assessing risk of radiofrequency and microwave radiation. We process data from a magnetic resonance imaging (MRI) scanner for retrieving electrical property maps for human body. In the talk, the MRI-based electrical property retrievals will be reviewed. The work done in my group at Singapore University of Technology and Design will be presented in detail. Two types of data are used, one is RF magnetic fields (B1-maps) and the other is phase maps. For B1-maps, we have proposed a few methods including taking approaches of analyzing Maxwell equations analytically and numerically. For phase maps as inputs, our contributions will be detailed. Corresponding results for different methods will be shown and discussed. Discussions and future challenges in this area will be presented as well.
