Most personal computers contain 8-bit graphic display hardware, whereas most medical gray scale images are stored at 16-bit per pixel integers. To display medical gray scale images on such computers, the 16-bit image data must be remapped into 8-bit gray scale images. This report presents the algorithms and computer code that allow very rapid 16-bit to 8-bit image data transformation. These algorithms are helpful in allowing personal computers with at least the performance of a Macintosh II (Apple Computer, Cupertino, CA) computer to function as low-end picture archiving communication systems or personal workstations.
大多数个人计算机包含8位图形显示硬件，而大多数医学灰度图像以每像素16位整数存储。为了在这类计算机上显示医学灰度图像，必须将16位图像数据重新映射为8位灰度图像。本报告介绍了能实现非常快速的16位到8位图像数据转换的算法和计算机代码。这些算法有助于使至少具备麦金塔II型（苹果电脑公司，加利福尼亚州库比蒂诺）计算机性能的个人计算机用作低端图像存档通信系统或个人工作站。
