In veterinary diagnostic medicine, patients cannot be instructed to hold their breath during x-ray imaging, which creates difficulty in timing a proper exposure. This leads to a two-fold problem: (i) a quality control issue, with many images unsuitable for diagnosis; (ii) a workplace safety issue, with increased radiation exposure to veterinary care providers, as repeated images need to be acquired. In this project, an automated x-ray exposure computing and triggering system will be designed and tested, in conjunction with the industry partner Prairie Veterinary Diagnostic Imaging (PVDI). This novel system will improve veterinary x-ray imaging workflow and decrease the need for repeating images, thus decreasing radiation exposure to the patients and technical staff. The outcome of this project should facilitate the industry partner, PVDI, in integrating this novel x-ray exposure computation and automated triggering system into clinical imaging systems, as well as becoming a component in a newly designed radiography unit specific to the needs of veterinary practice. This technology has applications in human medicine as well, particularly in pediatric radiology where many of the same problems with patient compliance are encountered.

在兽医诊断医学中，无法指导患者在 X 射线成像期间屏住呼吸，这导致难以确定正确的曝光时间。这导致了两个问题：（i）质量控制问题，许多图像不适合诊断； (ii) 工作场所安全问题，由于需要重复采集图像，兽医护理人员受到的辐射增加。在该项目中，将与行业合作伙伴 Prairie Veterinary Diagnostic Imaging (PVDI) 一起设计和测试自动 X 射线曝光计算和触发系统。这种新颖的系统将改善兽医 X 射线成像工作流程，减少重复图像的需要，从而减少患者和技术人员的辐射暴露。 该项目的成果应有助于行业合作伙伴 PVDI 将这种新颖的 X 射线曝光计算和自动触发系统集成到临床成像系统中，并成为专门针对兽医实践需求而新设计的放射线摄影装置的组成部分。这项技术在人类医学中也有应用，特别是在儿科放射学中，在患者依从性方面遇到了许多相同的问题。
