Optical klystron FEL scheme for x-ray coherent harmonic generation at ISLF storage ring
The possibility of inserting an optical klystron on the storage ring of an Iranian Light Source Facility as a Synchrotron Radiation Free electron Laser for coherence harmonic generation in the soft x-ray spectrum has been studied. The study has been performed using the 3D FEL simulation code GENESIS 1.3 and in accordance with the available characteristic parameters of ISLF. Different potential ...
متن کاملEmpirical correlation for porosity deduction from X-ray computed tomography (CT)
For obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as X-ray computed tomography, CT, seems to be precise and accurate. Porosity is deducted from the CT image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. More than one hundred samples with carbonate li...
متن کاملX-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...
متن کاملTransaxial computer tomography of lower extremity lymphedema.
We examined retrospectively 11 patients with isolated unilateral lower limb lymphedema (clinical criteria confirmed by isotope lymphography) using computer tomography. In conjunction with earlier observations, the findings of soft tissue stranding, skin thickening, fat deposition in the epifascial compartment and perimuscular fascial thickening and edema relate to lymph stasis. This noninvasive...
متن کاملX-ray scattering tomography for biological applications.
The conventional attenuation contrast imaging does not yield satisfactory sensitivity and specificity for weakly absorbing media, such as biological soft tissues. The x-ray scattering offer an important contrast mechanism to reveal structural features and density fluctuation within an object. This scattering signal carries information at the molecular and supra-molecular level, and has a tremen...
