柯达DV8900激光成像仪维修4例

柯达DV8900型干式激光成像仪是遵循DICOM医疗成像协议来接收数字图像数据,它是一种连续色调的激光成像仪,它含有内部相片热敏成像胶片显影器,用于冲洗胶片的是热度,而非冲相化学物质,因此具有所有影像均以650dpi（输出分辨率）打印,图像噪声低,灰阶级数高（16384级）,像素高（最高9100×11037）,高速打印胶片（200张/h）的特点。我院所有影像设备胶片均由激光成像仪打印,由于打印任务繁重,在常年的使用中难免发生故障。通过对柯达DV8900激光成像仪常见故障的阐述,提出一些简单有效的处理方法,供临床工程师参考。

Four cases of troubleshooting for Kodak DV8900 laser camera

Kodak Dryview8900 laser camera receives the digital image data by following the DICOM standard.It＇s a continuous-tone laser imager and contains an internal photo thermal imaging film developer with heat in stead of chemical substance.All images were printed in 650 dpi（Output resolution）,high speed,low image noise,ash high class（16384）,pixels high（Max9100＊11037）features.All imaging devices in our hospital obtain films by laser photo printing.Because printing is a heavy task,failure often occurs during its work.In this paper,the authors put forward some simple and effective methods of troubleshooting for the device through analyzing the common breakdowns in it for reference of our counterparts.
