摘要： Embodiments for correcting a dropout in a strain image in an ultrasound system are disclosed. In one embodiment, a processing unit sets a first window on each of pre-compression ultrasound frame data and post-compression second ultrasound frame data, move the first window in a predetermined direction and compute a correlation between the pre-compression ultrasound frame data and the post-compression ultrasound frame data within the first window to obtain a displacement corresponding to a value of each pixel of target ultrasound frame data. The processing unit sets one of pixels of the target ultrasound frame data as a reference pixel, sets a second window to encompass predetermined numbers of pixels positioned around the reference pixel, checks whether a displacement computation error corresponding to a dropout occur based on the pixel values within the second window and resets, when the dropout occurs, the value of the reference pixel.

摘要： There is provided an ultrasound system for forming strain images by decreasing decorrelation of receive signals, which vary with time or space. More specifically, the decorrelation between the receive signals obtained without and with applying stress to a target object is reduced to decrease an error, which occurs during the calculation of a delay. Also, a center frequency, which varies with depth of a target object, is compensated to form the strain image.

摘要： An embodiment for adaptively performing persistence processing on elastic images in an ultrasound system is disclosed. An ultrasound data acquisition unit sequentially acquires a plurality of ultrasound data frames based on ultrasound echo signals reflected from a target object by repeatedly applying and releasing stress to/from the target object. A processing unit calculates inter-frame displacements of the frames between the ultrasound data frames to form elastic images. The processing unit adaptively performs persistence processing on the elastic images in consideration of application or release of the stress to/from the target object.

摘要： The present invention is directed to an ultrasound system and a method of forming an elastic image, which are capable of preventing the distortion of the elastic image. The persistence of the previous frame and the present frame is performed after moving the boundary pixels set up in the previous interest frame to the boundary pixels in the present interest frame. This is so that the distortion of the elastic image may be reduced and the signal to noise ratio may be increased.
