Abstract
An ultrasound imaging system includes an array of ultrasound transducer elements chat send ultrasound energy into an object when energized for respective transmission time periods and provide responses to ultrasound energy emitted from the object for respective reception time periods, a reception modulation circuit modulating the responses with irregular sequences of modulation coefficients, a combiner circuit combining the modulated responses, and an image reconstruction processor configured to computer-process the combined modulated responses into one or more images of the object.
Claims7
An ultrasound imaging system comprising:
- a multi-element set of ultrasound transducer elements;
- an excitation pulse generator providing a succession of excitation pulses to the ultrasound transducer elements;
- a receiving switch matrix modulating echoes received by the ultrasound transducer elements in response to the excitation pulses applied to an object, with a random sequence of modulation coefficients;
- a circuit summing the modulated echoes in an analog domain;
- and the image reconstruction processor configured to apply an imaging matrix to the summed modulated echoes to thereby generate one or more images of the object;
- wherein the imaging matrix is a combination of transmitted excitation waveform matrix, propagation matrix, and beamforming function.
