X-ray Computed Tomography Using Synchrotron Radiation.

Fluorescent X-Ray Computed Tomography Using Synchrotron Radiation Towards Molecular Imaging

Presently, nuclear imaging techniques such as positron emission tomography (PET), and single photon emission CT (SPECT) are quite vital tools in clinical medicine as molecular imaging modalities to investigate the cause, diagnosis and therapy of diseases, e.g., Alzheimer’s disease, Parkinson’s disease, ischemic heart disease, cardiomyopathy and cancer, from the viewpoint of molecule. On the oth...

Improvement of imaging speed in fluorescent x-ray computed tomography using synchrotron radiation

Improving the speed of fluorescent X-ray CT imaging using synchrotron radiation has been studied from the points of view of the imaging system and the processing algorithm. Regarding the imaging system, high-speed imaging at 2 seconds per point with a dead time of about 6% has been realized by incorporating an electronic system which operates stably in the high count rate region. In addition, t...

Dose fractionation in synchrotron radiation x-ray phase micro-tomography.

Phase sensitive x-ray imaging expands the applicability of standard attenuation based techniques by offering several orders of magnitude of increase in sensitivity. Due to the short wavelength, x-ray phase is not directly measurable, but has to be put in evidence by the use of phase contrast techniques. The phase can then be reconstructed from one or several phase contrast images. In this study...

X-ray computed tomography.

X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today. CT has shown a steady upward trend with respect to technology, performance and clinical use independent of predictio...
