Comparison of FD-TD and Experimentally Determined Local SAR Values in a Rhesus Monkey Model
Microwave dosimetry has frequently relied on the used of phantoms to measure microwave dose for biological exposures. Here we report the use a homogeneous rhesus monkey phantom, the “green monkey”, to verify the results of a FD-TD computer model. The same techniques previously used to develop heterogeneous models of rat, goat and rhesus monkey from whole-body MRI scans1 were used to create a model of the “green monkey.” A phantom was prepared and subjected to a complete MRI scan. The resulting images were used to construct an accurate computer model of the phantom. FD-TD runs were performed at a range of frequencies using the geometry of the coded phantom. Local SAR values from the FD-TD output were used to select locations for local temperature measurements in the phantom.
