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

摘要： There is provided an ultrasound system for constructing or reconstructing an image with the use of pre-stored data and additional signals. The ultrasound system includes: a probe including a number of transducers for transmitting ultrasound transmission signals to a target object, receiving echo signals reflected from the target object and transducing the echo signals into electrical signals; an analog-to-digital conversion unit for converting the electrical signals into digital data; a transducer information collecting unit for collecting information on spatial states of the transducers at the time of receiving the echo signals; a beam-former for forming reception beams based on the converted digital data and the collected information; and an ultrasound image processing unit for reconstructing an ultrasound image based on the reception beams.
