A six-year experience of the first cassetteless radiology department has shown that it produces considerable improvement in speed and efficiency of patient handling, reduced physical labor for the technician, and substantial financial savings, amounting to approximately one third of the total non-medical budget. This is contrasted with the potential cost of a totally digital (filmless) department. The digital acquisition devices and their image processing systems are considerably more expensive. Image display comparable to conventional radiographys (for example the full-sized chest film) is markedly inferior in resolution and totally prohibitive in cost. Image storage and recall of the same amount of data as currently handled by the conventional department are presently beyond the capabilities of any commercial communications system, and the potential cost is completely unacceptable. Projections of the imminent advent of the filmless department are grossly over-optimistic, whereas the development of cassetteless systems offers an alternative route to improved patient handling and increased cost-efficiency.
首个无胶片放射科六年的经验表明，它在患者处理速度和效率方面有显著提升，减少了技术人员的体力劳动，并节省了大量资金，约占非医疗预算总额的三分之一。这与完全数字化（无胶片）科室的潜在成本形成对比。数字采集设备及其图像处理系统要昂贵得多。与传统X光摄影相当的图像显示（例如全尺寸胸片）在分辨率上明显较差，且成本高得令人望而却步。存储和调用与传统科室目前处理量相同的数据，目前任何商业通信系统都无法做到，其潜在成本也完全不可接受。对无胶片科室即将到来的预测过于乐观，而无胶片系统的发展为改善患者处理和提高成本效益提供了另一条途径。
