| Outline of Final Research Achievements |
Parametric radiation based X-ray (PXR), one of the pioneering studies using accelerator, is studied and expected for a kind of new X-ray source. In the Laboratory for Electron Beam Research and Application institute of quantum science (LEBRA). The purpose of this study was to evaluate the potential of LEBRA- parameteric X-ray as a new X-ray source for diagnostic imaging.
Compared to conventional X-ray, LEBRA-PXR images showed contrast related to different wavelengths, reflecting histological differences between tissues. Comparing histological findings, malignant tumor images with LEBRA-PXR revealed more clearly than that of conventional X-ray image. Using LEBRA-PXR, nearly perfect monochromatic X-ray source imaging, the images of malignant tumor displayed different contrasts from conventional X-ray. LEBRA-PXR produce a useful diagnostic imaging tool as a new X-ray source.
