Ultrasonic Linear Array Medical Imaging System
Modern ultrasound scanners use large either linear or phased array of piezoelectric transducers. Design principle of electronic beamforming networks thus draws heavily from that of adaptive antenna array. However, the interaction of ultrasound with human tissue appears to be much more complicated than that of the electromagnetic wave. While with Xrays we get a shadow image of the system, with u...
متن کاملPhased array ultrasonic imaging using an improved beamforming based total focusing method for non destructive test
One of the novel ultrasonic phased array based scanning methods for ultrasonic imaging in non-destructive test is total focusing method (TFM). This method employs maximum available information of the phased array elements and leads to an improved defect detection accuracy compared to conventional scanning methods. Despite its high detection accuracy, TFM behaves weak in distinguishing the real ...

متن کاملHigh Speed Imaging of Cavitation around Dental Ultrasonic Scaler Tips
Cavitation occurs around dental ultrasonic scalers, which are used clinically for removing dental biofilm and calculus. However it is not known if this contributes to the cleaning process. Characterisation of the cavitation around ultrasonic scalers will assist in assessing its contribution and in developing new clinical devices for removing biofilm with cavitation. The aim is to use high speed...
متن کاملExperimental investigation on the effect of injection pressure and injector installation angle on the penetration of the gasoline port fuel injector using high speed imaging method
The development of spray is one of the important factors effecting the combustion of PFI engines. This research was carried out in order to investigate some of the spray characteristics from PFI injector. In this study, the injector flux was investigated by a mass method and equations for it were presented. The results showed that in the pressure interval (2 to 6 bar), the relation of flux with...
