Abstract
A beamforming apparatus configured to beamform ultrasound waves transmitted through an ultrasound transducer having a two-dimensional transducer array includes a transmitter configured to output transmission pulses configured to drive elements constituting the transducer array, and a transmission switch configured to select at least two elements among the elements to form an aperture such that the transmission pulses drive the elements forming the aperture.
Claims20
A beamforming apparatus configured to beamform ultrasound waves transmitted through an ultrasound transducer having a two-dimensional transducer array, the beamforming apparatus comprising:
- a transmitter configured to output transmission pulses for driving elements constituting the transducer array;
- and
- a transmission switch configured to select at least two elements among the elements to form an aperture such that the transmission pulses drive the elements forming the aperture.
A beamforming apparatus comprising:
- a transmitter configured to output transmission pulses to at least two elements among elements constituting a transducer having a two-dimensional transduce array, the at least two elements forming an aperture;
- a receiver configured to focus ultrasound echo signals received by the at least two elements and thereby form a reception beam;
- and
- limiters connected to the respective elements constituting the transducer array and configured to protect the receiver from a high voltage occurring when the transmitter is driven.
