Small ultrasound transducers

摘要

A miniaturized ultrasound transducer (e.g. less than 4 mmx4 mmx10 mm) is provided and is operable in small spaces, such as a blood-vessel-size type of underfluid structure. The ultrasound transducer may be mounted onto or incorporated into a holding device to be easily manipulated. The ultrasound transducer communicates with a processing unit via an electrical wire or cable or wirelessly.
