2D Neural Network Method and apparatus of 2D sample volume based spectral Doppler imaging for motion tracking by using Neural Networks

摘要

An ultrasound imaging device according to an embodiment of the present invention comprises: an ultrasound transmission/reception unit; a data acquisition unit; and a motion tracking unit. The ultrasound transmission/reception unit may generate a two-dimensional sample volume by focusing and transmitting a wide beam ultrasound signal to one line of an ultrasound image, and receiving a received ultrasound signal reflected from an object. The data acquisition unit may store received data corresponding to the received ultrasound signal, and provide IQ data corresponding to an in-phase component and a quadrature component of the received data. The motion tracking unit may detect a motion of the object on the basis of a correlation value between a one-dimensional sample volume corresponding to a previous frame generated according to the IQ data and a two-dimensional sample volume corresponding to a current frame, and provide motion data. According to the present invention, sensitivity and image quality of an ultrasound image can be improved.
