3D Microwave bone imaging

We are developing a microwave imaging system for interrogating the calcaneus bone as a way of monitoring bone health progression in diseases such as osteoporosis. We have previously shown that the dielectric properties of trabecular bone correspond well to the associated bone volume fraction which can be used as a good indicator of fracture risk. We present 3D results showing that the technique is sophisticated enough to recover the pertinent structures and that ultimately this technique will be sufficiently sensitive for disease monitoring.
