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...

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...

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...

Contemporary X-ray electron-density studies using synchrotron radiation

Synchrotron radiation has many compelling advantages over conventional radiation sources in the measurement of accurate Bragg diffraction data. The variable photon energy and much higher flux may help to minimize critical systematic effects such as absorption, extinction and anomalous scattering. Based on a survey of selected published results from the last decade, the benefits of using synchro...

X-ray synchrotron radiation and particle acceleration

I discuss X-ray synchrotron emission as a probe of particle acceleration, concentrating mainly on low-power (FRI) jets but also touching on the hotspots in FRII sources. Combining X-ray and radio data has allowed us to locate the sites of high-energy particle acceleration, and hence jet kinetic energy dissipation, in a number of objects. Recent data solve some old problems but present some new ...
