| 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 repeatability 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. |
