    • In an ultrasonic diagnostic apparatus using an ultrasonic probe of a mechanical radial scanning type for intracavity observation, stable Doppler mode images with respect to an ROI or a gate position can be generated by reducing an influence of uneven rotation of a flexible shaft. The apparatus includes: a signal processing unit for performing orthogonal detection processing or orthogonal sampling processing on a reception signal to generate a complex baseband signal; a memory for storing the complex baseband signal for at least two frames generated based on ultrasonic echoes received along plural lines; a line selecting unit for selecting one line in each frame from among the plural lines based on the complex baseband signal; and an image signal generating unit for generating an image signal representing information on blood flow based on the complex baseband signal with reference to the line selected in each frame.
