摘要
Abstract
Objective To solve the problem of respiratory coordination in chest radiography in infants and young children. Methods A new X-ray machine exposure time display&control device was designed based on respiratory-gated devices, which monitored the changes in abdominal pressure during breathing by using the clamp signal acquisition system and used the STC89C52 single chip computer as the core of signal processing systems so as to real-timely display the abdominal pressure waveform. Altogether 100 infants with ages ranging from 1 to 3 years old were scanned by chest X-ray in the hospital, they were randomly selected and evenly divided into two groups with 50 infants in each group. One group was scanned by using the conventional method;another group was exposed by using the assistance of the respiratory-gated method designed this study. Results The exposure result by using the respiratory-gating assisted method was significantly better than that of the traditional method, with significant difference between the two groups (P<0.001). Conclusion The exposure time control device of X-ray machine which designed based on respiratory-gated display devices could provide better quality assurance for chest radiography.关键词
