The auto-measuring and analysis for ultrasound field based on a high-precise robotic system

Abstract

To meet the needs of design and analysis for special ultrasound transducer and complex multi-parameters array of ultrasonic transducers, a robotic system was developed to measure and analyze the feature of complex ultrasound field. The system integrated with mechanical robot, electronic control, hydrophone and measurement and analysis software modules. The system can automatically scan the whole field in any direction and locate at any point with high spatial resolution, precise (0.05 mm) and good frequency response to overcome the problems of measurement, analysis and modeling for complex ultrasound transducer. A standard focused ultrasound field was used to verify accuracy of the measuring system, and modeling results of measured data was consistent with ultrasonic theory model. The results indicated that the auto-measuring system and analysis model have good veracity to analyze and model complex ultrasound field, and provides an effective way to evaluate the design of complex and special ultrasonic transducer. It can also be used to study biological effects with feature of special ultrasound field in clinical application and to assess real treatment effect in animal treating experiment with automatically measuring and analysis. The system also can apply to evaluate the field produced by any kind of shockwave.
