Holographic subsurface imaging for medical detection

Holographic subsurface imaging radar (HSIR) has high plane imaging resolution, and has the potential in the application of human body inspection. This paper studies mainly on the feasibility of using HSIR in the medical diagnosis. A series of experiments have been carried out to image the different parts of human body, including palm, forearm, leg, knee, chest, back, and belly. The imaging results can show the shapes of bones in body tissues clearly, but the fat and muscle are not obvious. This indicates the permittivity difference between bone and other tissues is large, and the reflectivity from bone is also high. Moreover, the imaging results easily suffer the influence from the uneven human body surface.
