Abstract: There is provided a method of processing an ultrasound spectrum image. According to such method, a spectrum image is formed based on ultrasound data and then the noise is removed from the spectrum image. The noise-removed spectrum image is matched with one or more spectrum models representing specific spectrum types. Then, whether or not the noise-removed spectrum image contains an aliasing is checked. If the noise-removed spectrum image contains the aliasing, then the aliasing is removed from the noise-removed spectrum image to provide a noise-removed spectrum image without the aliasing. Thereafter, contour tracing is performed on the noise-removed spectrum image without the aliasing to detect contour points. Further, peak tracing is performed on the noise-removed spectrum image without the aliasing to detect peaks.

Abstract: In a method of compounding an ultrasound image, ultrasound signals having a transmission frequency are transmitted to a target object at a predetermined steer angle. Then, signals reflected by the target object are received. Based on the received signals, an image frame is formed. By repeating the above steps with different transmission frequencies, two or more image frames are obtained. The obtained image frames are then combined to provide a compound ultrasound image. The steer angle varies based on the transmission frequency.

Abstract: An ultrasound diagnostic apparatus and method for measuring a blood flow velocity effectively select one of the positive frequency range and the negative frequency range to compute noise threshold, and determine a reliability of the computed noise threshold. A sample data generator samples a reflected signal of the ultrasound signal transmitted into a human body.

A first determiner selects one of a positive frequency range and a negative frequency range of the frequency distribution data. A second determiner determines a noise threshold by using a predetermined number of frequency components within the frequency range selected by the first determiner. A third determiner determines a peak frequency component having the highest frequency among the frequency components.
