The flat-panel detector (FPD) has been introduced into clinical practice. A modified FPD, which has the ability to obtain dynamic chest radiographs, was introduced into our hospital, and clinical testing is ongoing. Both the inspiratory and expiratory phases have to be included in dynamic chest radiographs. The purpose of this study was to investigate the most appropriate chest radiography signal for observation of the respiratory process. We prepared ten protocol patterns that differed in terms of respiratory phase at X-ray exposure, exposure duration, and signal multiplicity. We also performed preliminary experiments and administered several questionnaires to ten volunteers. The volunteers breathed according to vocal and visual signals, and their respiratory waves were recorded by spirometer. The most appropriate protocol was similar to the method used for conventional chest radiography.
平板探测器（FPD）已被引入临床实践。一种能够获取动态胸部X光片的改良型FPD被引入我院，目前正在进行临床测试。动态胸部X光片必须包括吸气和呼气阶段。本研究的目的是探讨用于观察呼吸过程的最合适的胸部X光摄影信号。我们准备了十种协议模式，这些模式在X射线曝光时的呼吸阶段、曝光持续时间和信号多样性方面有所不同。我们还对十名志愿者进行了初步实验并发放了几份问卷。志愿者根据声音和视觉信号呼吸，他们的呼吸波由肺活量计记录。最合适的协议与传统胸部X光摄影所用方法相似。
