There are disclosed embodiments for an ultrasound system for providing a color M mode image and a brightness M mode image. A control unit calculates a time period expected to perform a first operation for the color M mode image and a second operation for the brightness M mode image once respectively, and determines an acquisition pattern defining an order of performing the first and second operations based on the calculated time period, a sweep period, and an ensemble number. The control unit controls the acquisition unit to perform, within the sweep period, the first operation a number of times equal to the ensemble number and the second operation one or more times according to the acquisition pattern. An image processor forms the color M mode image based on the first ultrasound data and forms the brightness M mode image based on the second ultrasound data.

There are disclosed embodiments for forming an enhanced elastic image in an ultrasound system. An elastic image of a target object may be formed by scanning N scan lines. A control unit divides the N scan lines into M scan lines groups by using an acquisition period necessary for transmitting and receiving ultrasound signals to acquire ultrasound data. An ultrasound data acquiring unit transmits ultrasound signals to a target object and receives the ultrasound signals reflected from the target object at a predetermined transmission/reception sequence for each of the M scan line groups. This forms ultrasound data corresponding to each of the M scan line groups while a pressure is applied to the target object. An elastic image forming unit forms at least one sub elastic image corresponding to each of the M scan line groups based on the ultrasound data. The elastic forming unit sums M sub elastic images corresponding to the respective M scan line groups to thereby form an elastic image of the target object.

Embodiments for filtering clutter signal from Doppler signal in an ultrasound system are disclosed. In one embodiment, a Doppler signal acquiring unit may transmit and receive ultrasound signals to and from a target object to acquire Doppler signal. A signal processing unit performs filtering upon the Doppler signal by using a first clutter filter having a first cutoff frequency and compute an input signal power to filtered input signal power rate (IFR) for the Doppler signal. The signal processing unit is further configured to be responsive to the IFR to modulate the Doppler signal and perform filtering upon the modulated Doppler signal by using the first clutter filter or to perform filtering the Doppler signal by using a second clutter filter having a second cutoff frequency.

The present invention relates to an ultrasound system for providing ultrasound images in a duplex mode. The ultrasound system comprises a transmission/reception unit for alternately transmitting a first ultrasound beam and a second ultrasound beam to a target object. The first and second ultrasound beams are transmitted for first and second time durations, respectively. The ultrasound system further comprises an image processing unit for forming a first diagnostic mode image based on echoes of the first ultrasound beam and a second diagnostic mode image containing a gap corresponding to the first time duration based on echoes of the second ultrasound beam. The image processing unit is further configured to perform gap filling based on edge points of the second diagnostic mode image to form a second diagnostic image with the gap removed.
