Title: MIRRORCLE-CV The Portable Synchrotron For Precise Non-Destructive Testing And Medical Diagnosis

Abstract

We are developing the portable synchrotron MIRRORCLE-CV series, which provides a high quality x-ray beam for high precision non-destructive testing (NDT). Computer simulations for the magnetic field design and electron dynamics reveal that the outer diameter of the synchrotron magnet can be as small as 30 cm. This synchrotron size approaches that of a conventional x-ray tube.

  • We started the development of the portable synchrotron MIRRORCLE-CV series, which provides a high quality x-ray beam for high precision non-destructive testing (NDT). Computer simulations for the magnetic field design and electron dynamics reveal that the outer diameter of the synchrotron magnet can be as small as 30 cm. This synchrotron size approaches that of a conventional x-ray tube.
  • The portable synchrotron MERRORCLE-6X is a novel x-ray source suitable for hard x-ray imaging. Highly brilliant x-rays are generated by MIRRORCLE-6X in the shape of cone from a source with micron size. We obtained images with high magnification and high resolution by these x-rays, and found that they can be utilized for medical imaging. Recently, we started to perform ideal 3-dimentional computed tomography (3D-CT) based on the Feldkamp algorithm, which is the most popular reconstruction algorithm for a cone beam CT, using a flat panel detector. Therefore, we developed a magnified 3D-CT system of high quality using MIRRORCLE-6X.
  • MIRRORCLE is a tabletop/portable synchrotron light source. It generates 10 mW order far infrared, watt order EUV/soft X-ray, and brilliant hard X-rays in 10 to 1000 keV range. MIRRORCLE is also a synchrotron that can generate directly monochromatic X-ray beam. MIRRORCLE is a medical diagnostics system similar to a X-ray tube radiology, but is very different in its fine spatial resolution and coherence of X-ray. A difference in the material density instead of in the atomic number is distinguished by the phase contrast method, due to its highly coherent beam. MIRRORCLE is a non-destructive testing system for more than 10cmmore » thick heavy constructions with 10-{mu}m order fine spatial resolution. MIRRORCLE is an EUV lithography source, a laboratory size protein crystallography system, as well as a X-ray microscope. We discuss advanced features of this multi-functional light source MIRRORCLE.« less
  • The portable synchrotron 'MIRRORCLE-6X' provides hard x-rays with high brightness and wide energy spectrum ranging from 10-300 keV, emitted from a micron-sized source, with wide divergence of {+-} 85 mrad. Correspondingly, images obtained using the 'MIRRORCLE-6X' showed significantly improved characteristics compared to conventional x-ray tube images, namely, improved refraction contrast, high resolution, and high magnification. Thus, the 'MIRRORCLE-6X' is considered to be a novel medical imaging source.A magnified image of a chest phantom, wherein a urethane ball of 8 mm diameter was implanted as an imitation of a cancer, was obtained. The detector used was an imaging-plate (Fujifilm imaging plate,more » FCR ST-IV) with 150 {mu}m pixel size. The phantom and the detector were respectively set at 50 cm and 540 cm from the x-ray source, so that the magnification was 10.8x. The x-ray source was a Cu 25 {mu}m rod. The resolution was about 25 {mu}m. Images with such high resolution and magnification cannot be obtained by conventional x-ray tubes with a source size of mm order. We can see the edges of costae and of the urethane ball at the back of the costae by the refraction contrast effect. Furthermore, we also see blood vessels surrounding the urethane ball. White spots, which are cross sections of blood vessels, were also observed. Therefore, observations of the shape of a cancer without surgical resection should be possible, and accurate diagnosis can be given using the 'MIRRORCLE-6X'.« less
  • We report that the magnified imaging using the portable synchrotron named MIRRORCLE has unique advantages for non-destructive inspection (NDI) of some products. This machine is a high energy x-ray source which can have a micron-sized point source, which is different from the conventional synchrotron, linear accelerator and the x-ray tube. The images produced with micron-sized point source and wide spectrum can display in detail the industrial products containing several materials in detail. The obtained x-ray images characterization is expected to provide a new tool for NDI of industrial products.
