Chest radiographs should be obtained at the peak of inspiration so that radiological findings can be precisely interpreted. However, this is not easily achieved, particularly in young children who do not follow the instruction to hold their breath. We developed a sensor that detects the breathing movements and conducted a randomized controlled study to determine whether the sensor would increase the proportion of chest radiographs obtained in the inspiration phase. We recruited 124 infants and children aged less than 3 years, who visited the pediatric department of a general hospital in Tokyo, Japan, and allocated them into one of two groups: with-sensor and without-sensor groups. Overall, 81% of all images were obtained during inspiration. The proportion of chest radiographs taken during inspiration was not statistically different between the two groups (81% vs. 82%). In the with-sensor group, radiologic technologists were able to obtain chest radiographs of the same quality while not observing the chest movement, but the sensor. The use of the sensor did not increase the proportion of chest radiographs taken in the inspiration phase in this study. However, this null result may indicate the possibility of utilizing the sensor for automatizing chest radiography in the future.
胸部 X 光片应在吸气高峰时获取，以便准确解读放射学发现。然而，这并不容易实现，特别是在那些不遵守屏住呼吸指令的幼儿中。我们开发了一种传感器，可以检测呼吸运动，并进行了一项随机对照研究，以确定传感器是否会增加吸气期获得的胸部 X 光片的比例。我们招募了 124 名年龄小于 3 岁的婴儿和儿童，他们在日本东京的一家综合医院儿科就诊，并将他们分配到传感器组和无传感器组。总的来说，81%的图像是在吸气时获得的。两组之间吸气时拍摄的胸部 X 光片比例没有统计学差异（81%比 82%）。在有传感器组中，放射技师可以在不观察胸部运动的情况下获得相同质量的胸部 X 光片，但可以观察传感器。在这项研究中，传感器的使用并没有增加吸气期拍摄的胸部 X 光片的比例。然而，这个无效结果可能表明未来有可能利用传感器实现胸部 X 光摄影的自动化。
