医疗费用的陡增和经营管理方面的压力,促使放射科考虑削减成本。作者对高分辨激光打印机在普通纸上打印的图像可否代替原始和复制的放射学胶片影像进行了研究。该研究使用的设备为1200点矩/吋和8bit性能的高质量激光打印机,并与Macintosh powermac 7200个人计算机相接。为了打印和图像处理,使用一个12bit的数字胶片扫描仪,扫描放射学照片。由商业图像处理软件制成不同宽度和间隙的几种平行线图形,星状图形及各种大
The steep increase in medical costs and the pressure on management have prompted radiology departments to consider cutting costs. The authors studied whether images printed on plain paper by high-resolution laser printers can replace original and reproduced radiographic film images. The device used was a high-quality laser printer with 1200 o’clock / inch and 8-bit performance and a Macintosh powermac 7200 personal computer. For printing and image processing, a 12-bit digital film scanner was used to scan radiographic images. By the commercial image processing software made of different widths and gaps of several parallel lines graphics, star graphics and a variety of large
