Abstract

An essential component that enables the progressive transition from the traditional film-based radiology to a filmless operation is the film digitizer. There are two kinds of film digitizers available on the market-laser scanners and CCD film digitizers. Their performances are compared in this paper. The operational characteristic, and thereby the performance, of a CCD digitizer is determined by a number of parameters. Adaptive calibration of these parameters is possible in order to fine-tune the CCD digitizer to better serve the application at hand.<>

自适应标定增强CCD胶片数字化仪
使传统的基于胶片的放射学逐步过渡到无胶片手术的一个重要组成部分是胶片数字化。目前市场上有两种胶片数字化仪,激光扫描仪和CCD胶片数字化仪。本文对它们的性能进行了比较。CCD数字化仪的工作特性和性能是由若干参数决定的。这些参数的自适应校准是可能的,以便微调CCD数字化仪,以更好地服务于手头的应用。
