A system is described which automatically identifies cephalometric landmarks on digital cephalometric radiographs. The accuracy of the automated system in identifying nineteen cephalometric landmarks is assessed. The accuracy obtained with the automated system is less than that of manual tracing. The automated system has particular difficulty in identifying landmarks which lie on poorly defined structures where there is a poor signal to noise ratio.
本文描述了一种能自动识别数字化头影测量X线片上头影测量标志点的系统。评估了该自动系统识别19个头影测量标志点的准确性。自动系统获得的准确性低于手工描绘。自动系统在识别位于结构定义不清、信噪比差的部位的标志点时尤其困难。
