直热式干式打印机的原理和临床应用

在医院集中式DICOM医用打印系统中，一台高速打印机往往连接着多台DICOM主机。各主机对输出图像的质量要求不同，所以要求打印机端适应主机的要求，控制打印图像质量，得到令人满意的胶片输出。本文以AGFADrystar5503干式打印机为例探讨直热式干式打印技术的原理和临床上的实际应用。直热式干式打印机能够输出连续的色调、丰富的灰阶与高质量的空间分辨率的优质图像，而且具备结构优化、性能稳定、出片速度较快、更环保等优点。

Principle and clinical application of direct dry printer

It was quite common and practicable that one high speed printer was connected to several DICOM modalities in hospitals with central printing system. For different image quality was demanded by different modalities, image quality should be controled at the printer side, to achieve acceptable high quality medical image on film. The principles and the application of the Direct Dry Printer were discussed in this article as an example. The characteristics of the Direct Dry Printer could produce good film with continuous tone, abundant grayscale and high-quality spatial resolution. It also had a number of other advantages such as improved structure, higher image quality, faster print speed and more friendly to the environment.
