Abstract
This study investigated the ability of microwave holography to accurately reconstruct the tissue structure of the human body. Numerical breast and head phantoms were imaged by 3D near-field holography using backscattered waves obtained by a monostatic planar scan. Complex organizational structures have been reconstructed accurately and quickly. In addition, breasts with relatively simple histology could be reconstructed without the matching liquid.
Highlights
Detection technology for breast cancer or brain strokes, based on microwave imaging, has been widely studied because it has no exposure, allows frequent examinations, and is relatively inexpensive as type of equipment [1] [2]

Summary
Detection technology for breast cancer or brain strokes, based on microwave imaging, has been widely studied because it has no exposure, allows frequent examinations, and is relatively inexpensive as type of equipment [1] [2]. Typical imaging methods include scattering tomography [3], which solves the inverse scattering problem to obtain the complex permittivity distribution in the object, and ultra-wideband (UWB) radar, which evaluates the scattered power distribution in the object using wideband signals [4]. The former has the ability to accurately reconstruct the tissue image. We demonstrate that a monostatic radar that captures backscattered waves in a planer scan can accurately reconstruct 3D tissue tomographic images of the breast and head in a short time by the use of near field holographic imaging
