ABSTRACT:
Methods and systems for receiving different types of signal formats from different ultrasound transducers are provided. A base unit of an ultrasound system includes a connector and receiver circuit for connecting with one of multiple different types of transducers. For example, a conventional transducer providing analog information associated with a single element on one receive channel is connected with the connector and receiver circuit. Alternatively, a transducer outputting time division multiplex or other multiplex information representing multiple transducer elements is connected with the connector and receiver circuit. The receiver circuit processes the received information differently depending on the data format. For example, the preamplifier impedance or gain is different for single element signals versus time division multiplex signals. As another example, a low pass filter bandwidth is larger for time division multiplex signals than for signals representing a single element. Receive circuits with an analog-to-digital converter positioned prior to a digital demultiplexer are also included for use with multiplexed data formats. Time division multiplex or other multiplex signals from a transducer array are converted to a digital format prior to demultiplexing. Methods and systems for adapting multiplexing or processing of multiplexed signals are also provided. A test signal or ultrasound signals are transmitted from a transducer to the receiver circuit and analyzed. The multiplexer of the transducer is synchronized with an analog digital converter with selectable delays responsive to the analysis. Coefficients or other filter characteristics of a digital equalizer are selected as a function of the analysis.
