Experimental study of dual calibration quantitative analysis in ultrasonic attenuation

目的探讨超声衰减双定标定量分析技术是否可获得高重复性的检测结果。方法在B超仪不同总增益、深度补偿增益条件下,以双定标体模块为参照物对待检测标本进行测试,并采集分组图像,使用自行研制的超声衰减定量分析软件进行分析。结果在B超仪不同总增益和深度补偿增益条件下检测结果具有高度重复性。结论超声衰减双定标定量分析技术可用于B超图像衰减的定量分析。

Objective To discuss whether ultrasonic attenuation dual calibration quantitative analysis may acquire highly repeatable checkout results. Methods With dual calibration phantom as references, under different total gain and depth compensation gain of B-mode ultrasonic scanner, test pending samples were tested. Different group images were collected and analyzed with self-developed ultrasonic attenuation quantitative analysis software. Results Test data had high repeat ability under different total gain and depth compensation gain of B-mode ultrasonic scanner. Conclusion Ultrasonic attenuation dual calibration quantitative analysis can be used for quantitative analysis of B-mode ultrasonic images.
