<P>PROBLEM TO BE SOLVED: To provide an ultrasonic image processor and a program which generate a Doppler waveform image having adaptively increased visibility according to the change of a measurement condition. <P>SOLUTION: The ultrasonic diagnosis apparatus includes: a frequency analysis unit for generating frequency spectrum data of the Doppler shift frequency component of ultrasonic wave transmitted to a subject, reflected in the subject, and received; and a line data generating unit for generating line data based on the frequency spectrum data, the line data defining a sequence of a plurality of pixels according to a corresponding frequency, the pixels having values each representing the magnitude of the Doppler shift frequency component. The ultrasonic diagnosis apparatus determines whether each of the pixels represented by one line data at a preset time address, is a noise pixel or not. A pixel determined as the noise pixel is adjusted to have a value obtained by multiplying the pixel value by a weighted coefficient w not lower than 0 and less than 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
