title: Performance evaluations for diagnostic x-ray equipment.
abstract: Technical factors influencing the performance of x-ray equipment are: focal spot size, focal spot growth, leakage radiation, accuracy of the exposure timer, kilovoltage, exposure reproducibility, linearity of exposure, x-ray beam quality, and collimation. An evaluation of these factors is necessary to determine x-ray equipment performance characteristics.
