Claim One:
1. An ultrasound system, comprising: an ultrasound data acquisition unit including an ultrasound probe configured to perform a transmit/receive operation including transmitting ultrasound signals to a target object and receiving rapidly changing ultrasound echoes reflected from the target object to thereby acquire multiple ultrasound data; and a processor configured to: form entropy information indicating a stochastic change degree of the multiple ultrasound data in an order in which the ultrasound data associated with the rapidly changing ultrasound echoes are acquired, form entropy change information indicating a difference between an i-th entropy information of the formed entropy information associated with the rapidly changing ultrasound echoes and an (i+1)-th entropy information of the formed entropy information associated with the rapidly changing ultrasound echoes, compare the entropy change information with a threshold in entropy change information, when the entropy change information is greater than the threshold in entropy change information, adaptively adjust coefficients of a filter for removing afterimage or removing noise in multiple ultrasound images and perform filtering for removing afterimage or removing noise in the multiple ultrasound images upon the multiple ultrasound data with the filter having the adjusted coefficients, when the entropy change information is equal to or less than the threshold in entropy change information, perform filtering for removing afterimage or removing noise in the multiple ultrasound images upon the multiple ultrasound data with the filter having preset coefficients, without adjusting coefficients of the filter, and the processor being further configured to form the multiple ultrasound images based on the multiple ultrasound data with the filtering performed.
