Quantification of cephalometric X-rays requires the use of hand tracings of the structures to delineate points, lines, and angles. The structures, especially soft tissue, are often obscure and are therefore approximated. Recent biomedical application of image enhancement by digital computer promises a method whereby landmarks in the cranium are more clearly defined. Development of this technique will enable a more extensive and accurate utilization of cephalometric radiographs for diagnostic and research purposes.
头影测量X线片的量化需要使用手工描绘结构来确定点、线和角度。这些结构,尤其是软组织,常常模糊不清,因此只能进行估算。数字计算机在图像增强方面的最新生物医学应用有望提供一种方法,使颅骨上的标志点能更清晰地界定。这项技术的发展将使头影测量X线片能更广泛、准确地用于诊断和研究目的。
