Nowadays, PGNAA applications in industrial, medicine, military,… are well known. A PGNAA system design requires simulations to determining some parameters, like gamma spectrum originated from shield, sample and surrounding materials, to ability, for example, to foreseen minimum detectable activity. Simulation codes use cross section libraries for calculating interaction probabilities and...
Introduction: Reduction of peak kilovoltage (kV) setting has been a useful approach to d creating radiation dose; however, it may have varied effects on noise and the accuracy of diagnosis. Thus, we compared image quality between low (80 kV) and standard kilovoltage (100 kV) protocols. Material and Methods: This triple blind non-randomized parallel quasi-experimental study was conducted on 140 ...
