摘要
以Matlab为工具实现CT性能参数层厚的自动测量,并将结果与传统手动测量进行对比。将扫描CT性能测试模体Catphan500获取的图像导入检测系统,绘制层厚的灵敏度剖面线,自动检测出全值半高宽(FWHM),其自动测量结果比传统手工测量结果更加准确,且耗时更少。基于Matlab实现CT扫描层厚的自动测量方法符合CT扫描层厚的定义,客观程度高,可用于CT应用中的质量检测。
Matlab was used as tool to realize automatic measure for slice thickness of performance parameter of CT, and the results were compared with that of traditionally manual measure. The images that obtained from phantom Catphan 500 of CT performance test were led in detecting system to draw section line of sensitivity of slice thickness and to automatically detect full width of half maximum(FWHM). The results of automatic measure are more accurate than that of traditional manual measure, and its time is lower. The method of automatic measure of the slice thickness of CT scan that is realized on the basis of Matlab conforms to the definition of the slice thickness of CT scan, and its objective degree is high. It can be used in the quality test of CT application.
