数字射线成像中原始图像数据的定义与保存
Definition and Preservation on Original Digital Image in Digital Radiography
摘 要
在数字射线成像检测方法中，需要明确原始图像数据的含义，并对其进行有效的保存与归档。通过分析得出，数字射线成像中原始图像应是数字射线探测器校正后得到的最初图像；原始图像数据经图像处理后可获得更好的视觉效果，但应注意方法的正确使用，避免改写原始数据；利用数据库技术可实现数字化射线检测图像的有效管理和归档。
原始图像数据
Digital radiography
Original digital image
Abstract
Original digital image in digital radiography needs appropriate archiving, and the definition of original digital image need to be specified first. It indicates following the analysis that the: original digital image should be the raw image from digital detector after calibration; better visual effect can be achieved by image processing techniques on original image. The original data should not be overwritten by some improper processing and management and archiving of original digital image can be done effectively by using database method.
