Method of producing ultrasound images using orthogonal nonlinear codes and apparatus thereof

摘要

PURPOSE: An ultrasonic image generating method and an apparatus thereof are provided to minimize degradation of axial resolution in generation of an ultrasonic image. CONSTITUTION: An ultrasonic image generating unit transmits N orthogonal nonlinear codes to different transmission focusing points(300). The ultrasonic image generating unit separates a receiving signal of the transmitted N orthogonal nonlinear codes with N receiving signals(310). The ultrasonic image generating unit synthesizes the separated N receiving signal according to a transmission focusing section(320).
