Reduced radiation dose and improved image quality using a mini mobile digital imaging system in a neonatal intensive care unit

摘要

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 mu Gy and 49.11 +/- 1.46 mu Gy, 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 161 pm. A newly developed mini DI is capable of preserving the diagnostic information with dose reduction in neonates under intensive care. (C) 2016 Elsevier Inc. All rights reserved.
