1、. 超聲波檢測領(lǐng)域的革命性技術(shù)-超聲透視成像技術(shù)Presented at the Ultrasonics for Nondestructive Testing Conference July 29, 2015安賽斯（中國）有限公司 Acoustography Basic Concept Uses a Super High Resolution Large Area Ultrasound Detector (AO Sensor)For Instant, Full-Field X-Ray like Ultrasound Imaging Acoustography BenefitsFULL FIEL

2、D: Area Inspection not point-by point inspectionNEAR REAL-TIME: Rapid screening of componentsHIGH LATERAL RESOLUTION: Ultrasound converted into visual image by minute moleculesSIMPLE: Visual Image is intuitive, easy to interpret compared with electronic signalsLOW-COST: lower skill operator results
