Abstract

It is necessary to get many good information from radiography of infant as same as an adult. Therefore we consider the following points in taking radiography of infant. Namely it is important to keep a patient in best position, and to expose in short time to catch at the inspiratory phase. Also it is desired to take radiogram of chest in upright position with an exposure time less than 10 millisecond, synchronously by using synchronous unit of respiramatic system and heart scope. Assistant to hold infant should use protecting apron containing 0.5mm thickness of lead from radiation.
