The development of digital radiography (DR) has provided numerous benefits for pediatric imaging, including the ability to post-process images and to make images immediately available for access by care providers. However, DR presents several significant challenges for the radiologic technologists who are responsible for operating the equipment and producing high-quality images in children. This paper discusses those challenges, including lack of standardization among vendors, particularly with regard to the exposure indicator; lack of pediatric-specific educational materials and pediatric techniques; the need for manual technique instead of the use of automatic exposure control in smaller children; and complications related to field size, collimation and shielding in small children. Specific actions and design modifications that might facilitate the effective management of these challenges will be also described. The implementation of measures to promote the production of optimal images while minimizing radiation exposure requires cooperation and communication among imaging professionals, manufacturers and regulatory agencies.
数字射线摄影（DR）的发展为儿科成像带来了诸多益处，包括对图像进行后处理以及使图像能够立即供护理人员访问的能力。 然而，DR 给负责操作设备和为儿童生成高质量图像的放射技师带来了一些重大挑战。 本文讨论了这些挑战，包括供应商之间缺乏标准化，特别是在曝光指示器方面；缺乏特定于儿科的教育材料和儿科技术；在较小的儿童中需要手动技术而不是使用自动曝光控制；以及与较小儿童的射野大小，准直和屏蔽相关的并发症。 还将描述可能有助于有效管理这些挑战的具体操作和设计修改。 为了在最小化辐射暴露的同时促进最佳图像的产生，需要影像学专业人员，制造商和监管机构之间的合作与沟通。
