FDTD Computational Analysis of X-ray Transmission and Scattering Characteristics in Medical Imaging Diagnosis
X-ray diagnosis depends on the intensity of transmitting and scattering waves in Xray propagation in biological media. X-ray is scattered and absorbed by tissues, such as fat, bone and internal organs. However, image processing for medical diagnosis, based on the scattering and absorption characteristics of these tissues in X-ray spectrum is not so much studied. Particularly, scattered waves in biomedical media cause serious deterioration of image quality. In this paper, X-ray transmission and scattering characteristics in biological media are studied using FDTD method with grid computer. Also, to remove the scattered waves and improve the medical image diagnosis, the waveguide-type grid filter is considered.
