Abstract
MIRRORCLE is a noble hard X-ray source, which is quite different from either X-ray tubes or synchrotron light sources (SLS) in many regards. MIRRORCLE generates very parallel and high-density photons like SLS, but the source emitter size is much smaller than SLS as well as tube. The radiation angular spread is much wider than SLS and similar to tube. Thus diagnosis of human body size is possible. The X-ray spectrum is polychromatic peaking around 30-200 keV, which is higher than SLS, while X-ray tube uses characteristic X-rays. The photon energy is selectable with MIRRORCLE by changing the target material and thickness. Because of these wonderful features the imaging by MIRRORCLE demonstrates 10 to 100 times magnifications, extremely sharp edge enhancement due to the phase contrast, and one micron order spatial resolution without optical elements. Density mapping is demonstrated in a simple plane magnified imaging. When tomography is applied, density volume mapping is obtained.
