A total of 40,000 portable examinations are performed each year at Shands Hospital (Gainesville, FL), a 570-bed teaching hospital. Radiographs are obtained using a screen-film combination with the films digitized for transmission to displays in four intensive care units. A cost-analysis of replacing screen-film with computed radiography (CR) integrated into a filmless picture archiving and communication system (PACS) network was performed. Equipment requirements included two CR units, three high-resolution dual monitor displays, and an archive to store 3 months of image data. The capital costs were amortized over a 5-year period. Capital and operating costs of the proposed expansion to the existing PACS network, together with anticipated cost savings, were determined. The maximum data transfer rate for portable examinations was 150 MByte per hour and approximately 400 GByte of image data are generated each year. These figures were used to determine the hardware requirements for handling the acquisition, transfer, and display of the images. Annual costs of the proposed expansion were about $220,000. Cost savings were achieved by elimination of film, including its handling by technologists/library clerks, and amounted to about $200,000 per year.
位于佛罗里达州盖恩斯维尔市的尚德医院是一家拥有570张床位的教学医院，每年共进行40000次便携式检查。通过使用屏片组合获取X光片，并将胶片数字化后传输至四个重症监护病房的显示器上。对将计算机X线摄影（CR）集成到无胶片图像存档与通信系统（PACS）网络中以取代屏片进行了成本分析。设备需求包括两台CR设备、三台高分辨率双显示器以及一个用于存储三个月图像数据的存档。资本成本在五年内摊销。确定了对现有PACS网络进行拟议扩展的资本和运营成本，以及预期的成本节约。便携式检查的最大数据传输速率为每小时150兆字节，每年大约生成400千兆字节的图像数据。这些数据用于确定处理图像采集、传输和显示的硬件要求。拟议扩展的年度成本约为220000美元。通过消除胶片（包括技术人员/图书馆职员对胶片的处理）实现了成本节约，每年约为200000美元。
