Radiation dose to personnel and low capacity X–ray equipment are obstacles to the optimal use of veterinary radiology. In order to find means to lower radiation dose and improve the quality of the radiographic image in veterinary radiology the authors have tested the so–called rare earth intensifying screens under experimental and clinical conditions. Of the basis of their findings they recommend the use of predominantly green light–emitting screen with lanthanum oxysulphide crystals activated with terbium, in combination with orthochromatic film. This combination was shown to give the best ratio image–screen noise. Considerable dose reduction was obtained with this system, and the image quality improved due to less blurring by motion.
