Statistical Characteristics of Transmitted Nano-meter lectromagnetic Waves in Random Bio-medical Tissues for X-Ray Diagnostic Images
Medical image diagnosis and computer aided diagnosis using X-rays are very im-portant technical tools for physiological diagnosis. Scattered X-ray fields disturb medical image signal properties given by X-ray transmission properties through biological structures concerned with X-ray absorption effects due to biological characteristics. In this paper, in order to improve image diagnosis, statistical analysis of X-ray is discussed for X-ray propagation, attenuation and scattering in random inhomogeneous biological media. Spatial filtering characteristics of grid structure for scattering X-rays particularly, for off-axis X-rays are shown for image X-ray projec-tion by mode theory of lossy waveguides for higher modes. Spatial grid filters consist of waveguide arrays of graded index inhomogeneous waveguides.
