With an emphasis on the regulatory framework, we describe three approaches that the U.S. Food and Drug Administration applies to promote dose control and radiation safety in X-ray computed tomography: (1) equipment radiation safety established throug

Accurately representing radiation dose delivered in MSCT is becoming a concern as the maximum beam width of some modern CT scanners tends to become wider than the 100 mm charge-collection length of the pencil ionization chamber generally used in CT d

Phosphor packages for a laser-heat thermoluminescence radiation-dosimetry system have been analyzed with Rutherford Backscattering Spectrometry and X-ray Photoelectron Spectroscopy. Samples consist of 20–50 μm diameter powder grains of CaSO4: Tm a

Stopping powers for 400 to 2400 keV N ions in He and Ar gas targets were measured using a time-of-flight technique. The stopping power was directly determined from changes in ion time-of-flight over a fixed distance after passing through a differenti

Stopping powers of the noble gases for 300-keV to 10-MeV nitrogen ions were measured using a time-of-flight technique. The stopping power was directly determined from changes in ion'time of flight over a fixed distance as a function of the target-gas
