Computed Radiography (CR) has become a major digital imaging modality in a modern radiological department. CR system changes workflow from the conventional way of using film/screen by employing photostimulable phosphor plate technology. This results in the changing perspectives of technical, artefacts and quality control issues in radiology departments. Guidelines for better image quality in digital medical enterprise include professional guidelines for users and the quality control programme specifically designed to serve the best quality of clinical images. Radiographers who understand technological shift of the CR from conventional method can employ optimization of CR images. Proper anatomic collimation and exposure techniques for each radiographic projection are crucial steps in producing quality digital images. Matching image processing with specific anatomy is also important factor that radiographers should realise. Successful shift from conventional to fully digitised radiology department requires skilful radiographers who utilise the technology and a successful quality control program from teamwork in the department.
计算机X线摄影（CR）已成为现代放射科主要的数字成像方式。CR系统采用光激励荧光板技术，改变了传统使用胶片/增感屏的工作流程。这导致放射科在技术、伪影和质量控制问题上的观点发生变化。数字医疗企业中提高图像质量的指南包括针对用户的专业指南以及专门为实现临床图像的最佳质量而设计的质量控制程序。了解CR从传统方法的技术转变的放射技师可以对CR图像进行优化。针对每个X线摄影投照进行适当的解剖学准直和曝光技术是生成高质量数字图像的关键步骤。使图像处理与特定解剖结构相匹配也是放射技师应认识到的重要因素。从传统放射科成功转变为完全数字化的放射科需要熟练运用该技术的放射技师以及科室团队合作成功实施的质量控制程序。
