Mode dependent tunable transducers and methods of use |
摘要 |
Transducer systems for mode dependent tuning and associated methods are provided. One or more tuning circuits are provided within a transducer probe. The tuning circuit is switchably connected to the transducer. By connecting or disconnecting the tuning circuit, the tuning for the transducer element is varied. Selective tuning of a medical ultrasound transducer allows different tuning for different modes of operation. For example, the frequency response of the transducer is varied between different modes of imaging, such as B-mode and flow-mode imaging. Higher frequency signals are used for higher resolution B-mode imaging, but a stronger response at lower frequency is desired for better penetration during flow-mode imaging and Doppler modes. Mode is used in a general sense, such as associated with an imaging mode as well as a type of operation (e.g. transmit mode versus receive mode operation).
