Abstract
There is provided an ultrasonic diagnostic apparatus in which transmission of ultrasonic waves into the subject and reception of the ultrasonic waves reflected within the subject are repeatedly performed to obtain a plurality of sequentially continued frames of image data, and a dynamic image is displayed in accordance with the image data thus obtained. According to the ultrasonic diagnostic apparatus, image data, which is transmitted to a storage unit for the purpose of an average arithmetic operation for the successive frame K+1, is selected for each pixel I from between two types of image data of an averaging image data B (K, I) after an average arithmetic operation processing and a new frame of image data A (K, I) before the average arithmetic operation processing. Thus, both the reduction of noises and the tracking ability to the movement are implemented with greater satisfaction.
