This study was aimed to assess the radiation dose and image quality of a mini-mobile digital imaging (mini-DI) system for neonatal chest radiography and compared to conventional digital radiography (DR). A total of 64 neonates were examined and anatomical landmarks were assessed. The entrance surface dose of mini DI and conventional DR was 26.64±0.15 μGy and 49.11±1.46 μGy, respectively (p<0.001). The mean SNR values for mini-DI and DR were 233.2±5.1 and 31.6±1.2, and 10% MTF values were 131 and 161μm. A newly developed mini-DI is capable of preserving the diagnostic information with dose reduction in neonates under intensive care.
本研究旨在评估用于新生儿胸部X线摄影的微型移动数字成像（mini-DI）系统的辐射剂量和图像质量，并与传统数字X线摄影（DR）进行比较。共检查了64例新生儿，并评估了解剖标志。mini-DI和传统DR的体表入射剂量分别为26.64±0.15μGy和49.11±1.46μGy（p<0.001）。mini-DI和DR的平均信噪比分别为233.2±5.1和31.6±1.2，10%调制传递函数值分别为131μm和161μm。新开发的mini-DI能够在降低剂量的情况下保留重症监护新生儿的诊断信息。
