ABSTRACT:
The preferred embodiments described herein provide electrical and mechanical enhancements for a modular transducer system. In one preferred embodiment, a multiplexer is provided to reduce the number of circuits required to support a given transducer configuration. The multiplexer can be integrated into the scan head or the receptacle assembly of the modular transducer system. In another preferred embodiment, a scan head is provided with circuitry operative to compensate for mismatch in electrical impedance by increasing energy transfer between the transducer array and the cable assembly. In yet another preferred embodiment, a scan head is provided with circuitry operative to form a band pass filter programmable by the medical diagnostic ultrasound imaging system. With a further preferred embodiment, a scan head is provided with a non-volatile memory device. Some other preferred embodiments describe mechanical enhancements for the modular transducer system. Other preferred embodiments are provided, and each of the preferred embodiments described herein can be used alone or in combination with one another.
