Abstract Accurate chest radiographs obtained during inspiration or expiration are important during clinical diagnosis. However, it is difficult to take such radiographs in infants because of their inability to cooperate. Our automatic exposure device was designed to obtain better chest radiographs in infants. The device is composed of 3 parts: a mask with a pressure sensor, an NEC PC-9801 personal computer, and an exposure device. The software, which analyzes intramask pressure signals and triggers the exposure at the appropriate time, was written in N88-BASIC(86).
