Abstract
A system for processing acoustic signals that includes a digital signal module and an analog signal module. The digital signal module is configured to generate a digital excitation pulse for activating one or more ultrasound transducers and is configured to receive a digital return signal representing a responsive return signal from the ultrasound transducers.
Claims20
A system for processing ultrasound signals, the system comprising:
- a controller module comprising one or more processors and configured to transmit control signals to an analog ultrasound signal module, the analog ultrasound signal module comprising:
- a common input/output port configured to transmit and receive the ultrasound signals to and from an ultrasound transducer;
- a return signal output port configured to transmit returned ultrasound signals to the controller module, the returned ultrasound signals received from the ultrasound transducer through the common input/output port;
- a first amplifier configured to receive transducer excitation signals and to amplify the transducer excitations signal in response to receiving a first control signal from the controller module;
- a combiner comprising first and second combiner input terminals and a combiner output terminal, the combiner output terminal arranged to transmit and receive the ultrasound signals to and from the common input/output port of the analog ultrasound signal module, the first combiner input terminal configured to receive amplified ultrasound excitation signals from the first amplifier and direct the excitation signals to said common input/output port;
- and
- a first switch having an input configured to receive the ultrasound signals from the second combiner input terminal, the first switch configured with an output and a first state that directs received ultrasound signals to a termination and configured with a second state that directs received ultrasound signals to the return signal output port, the first switch configured to change between the first state and the second state in response to receiving a second control signal from the controller module.

A method of processing ultrasound transducer signals, the method comprising:
- receiving an excitation signal for exciting an ultrasound transducer;
- directing the excitation signal through an amplifier while activating the amplifier;
- directing the excitation signal through a first input port of a combiner and through an output port of the combiner to a transducer;
- receiving a return transducer signal at the output port of the combiner and directing the return transducer signal to a first switch;
- directing the received return transducer signal from the first switch to a termination while the amplifier is activated by the first control signal;
- and
- directing the received return transducer signal from the first switch to a return signal output while the amplifier is inactive.
