Basic study of parametric X-ray radiation for clinical diagnosis using 125MeV linear particle accelerator

Abstract

We demonstrated some different contrasts of cat mandibular squamous cell carcinoma using parametric X-ray radiation at the Laboratory for Electron Beam Research and Application at Nihon University (LEBRA-PXR). A conventional X-ray image revealed a bone tumorous lesion in the mandible. LEBRA-PXR images (20, 25 and 30KeVs) showed some contrasts related to the wavelengths. LEBRA-PXR displayed contrasts which differed from those of conventional X-ray images, suggesting LEBRA-PXR may be useful for diagnostic imaging as a new X-ray source.
