ORGAN AND EFFECTIVE DOSE COEFFICIENTS FOR CRANIAL AND CAUDAL IRRADIATION GEOMETRIES: PHOTONS

Calculations of absorbed dose and energy dependent of small-scale dosimeters for photons beam therapy

In this study, the energy dependency for dosimeters of air ionization chambers, lithium fluoride, silicon and plastic scintillator has been studied using the MCNPX Monte Carlo simulation code and simulated for gamma energy in the range of radiotherapy energy. The simulation results show that the response of each of the dosimeters for gamma photon beams in the energy range of 0.2 to 20 MeV varie...

RADIOLOGY Cranial and Caudal Angulation for Coronary Angiography Revisited

Several similar projections utilizing cranial and caudal angulation of the X-ray tube in various obliquities have been described recently for coronary angiography and left ventriculography. These views provide improved visualization of the proximal branches of the left coronary artery, the region of the crux of the right coronary artery, and the left ventricle in the left anterior oblique proje...
