Abstract
Official abstract text for this publication.
A method of ultrasound nonlinear imaging with high-bit Golay code excitation includes transmitting a first, a second, a third and a fourth Golay code signal wave which have more than four bits and are orthogonal pairs to each other; making the second and the forth Golay code signal wave be subtracted from the first and the third Golay code signal wave respectively to eliminate noise interference wave; performing compression filtering process to the above generated waves and taking a cross sum to generate two compressed code waves; taking the difference between the two compressed code waves to generate an image wave which includes at least two second-order harmonic waves; processing ultrasound nonlinear imaging by using the second-order harmonic waves and to generate an ultrasound image.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of ultrasound nonlinear imaging with high-bit Golay code excitation comprising the steps of: (a) receiving a first Golay code signal wave, a second Golay code signal wave, a third Golay signal wave, and a fourth Golay signal wave, wherein the first Golay code signal wave includes at least two first second-order harmonic waves and at least one first noise interference wave, the second Golay code signal wave includes at least two second second-order h…
