Title:
マルチビーム送信分離
Document Type and Number:
Japanese Patent JP2010514322
Kind Code:
A
Abstract:
A method for isolating ultrasound transmit beams and reducing cross-transmit beam interference in a multi-beam system involves transmitting a first ultrasound beam at a first and second positive angle and transmitting a second ultrasound beam at a first and second negative angle. The method further involves receiving a first, second, third, and fourth composite signals, where each of the composite signals includes a return signal and a reflected component. The method further includes applying a finite impulse response filter to the first and third composite signals and the second and fourth composite signals to obtain an average of the first and second composite signals and an average of the second and fourth composite signals and remove the reflected components.
