Patent ID: 7951082

Claim:
An ultrasonic diagnostic apparatus comprising: an acoustic line data generation unit operable to generate acoustic line data based on echo signals acquired via a probe; a display data generation unit operable to generate display data for the generated acoustic line data; and a display unit operable to display an image describing an inner state of a subject based on the generated display data, wherein the display data generation unit includes interpolation algorithms of different processing loads, and is operable to (i) select one of the interpolation algorithms so that a processing rate of the interpolation algorithm, at which the display data is generated from the acoustic line data, is equal to or above an acquisition rate of the acoustic line data generated by the acoustic line data generation unit or is equal to or above a renewal rate of the display data of the image, and to (ii) perform a process for generating the display data using the selected interpolation algorithm, so as to change the quality of the image describing the inner state of the subject and to generate the display data of the changed quality.
