BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204545 DESCRIPTION An 82-year-old woman was admitted to our hospital because of syncope. A 12-lead ECG demonstrated atrial fibrillation with a ventricular response of 35 bpm, and a VVIR (ventricular pacing, ventricular sensing, inhibiting mode...

The purpose is to review in a 4-part series: (i) the basic principles of x-ray production, (ii) x-ray interactions and data capture/conversion, (iii) acquisition/creation of the CT image, and (iv) operational details of a modern multislice CT scanner integrated with a PET scanner. Advances in PET technology have lead to widespread applications in diagnostic imaging and oncologic staging of dise...

A laser-driven electron-storage ring can produce nearly monochromatic, tunable X-rays in the keV energy regime by inverse Compton scattering. The small footprint, relative low cost and excellent beam quality provide the prospect for valuable preclinical use in radiography and tomography. The monochromaticity of the beam prevents beam hardening effects that are a serious problem in quantitative ...
