Initiated by complaints of image artifacts, a thorough visual and radiographic investigation of 197 Fuji, 35 Agfa, and 37 Kodak computed radiography (CR) cassettes with imaging plates (IPs) in clinical use at four radiology departments was performed. The investigation revealed that the physical deterioration of the cassettes and IPs was more extensive than previously believed. It appeared that many of the image artifacts were the direct result of premature wear of the cassettes and imaging plates. The results indicate that a quality control program for CR cassettes and IPs is essential and should include not only cleaning of the cassettes and imaging plates on a regular basis, but also visual and radiographic image inspection to limit the occurrence of image artifacts and to prolong the life cycle of the CR equipment.
在收到有关图像伪影的投诉后,对四个放射科临床使用的197个富士、35个爱克发和37个柯达计算机X线摄影(CR)暗盒及成像板(IP)进行了全面的视觉和射线照相检查。调查发现,暗盒和IP的物理损坏程度比之前认为的更为严重。许多图像伪影似乎是暗盒和成像板过早磨损的直接结果。结果表明,CR暗盒和IP的质量控制程序至关重要,不仅应定期清洁暗盒和成像板,还应进行视觉和射线照相图像检查,以限制图像伪影的出现并延长CR设备的使用寿命。
