EXPOSURE TIME TABLE FOR EQUINE PRACTICE Values are for High-Frequency X-Ray unit Atomscope HFX90V with orthochromatic intensifying screens (”RARE EARTH” - Gadoliniumoxybromide), G R E E N S E N S I T I V E Factor 400. In order to obtain uniform quality of radiographs, it is important to use same film- and chemical brand products consistently. Low quality film material can cause considerable image problems. All data are standard values, slight adjustments might be necessary, depending on the conditions at site. As a general rule, exposures with utilization of an X-ray grid need 2 - 3 times longer exposure times. REGION X-RAY
