<p>Provided is an ultrasonic diagnostic device which has a spatial resolution that is spatially uniform and is capable of reconstructing an image suitable for diagnosis as required. A device which transmits an ultrasonic pulse to a subject and constructs an image using the received pulse from the subject, wherein a processing unit which constructs an ultrasonic image estimates a degradation factor that degrades an image for each space, formulates the effect of the degradation factor as a transfer function, calculates, using the transfer function, degradation-removed data obtained by removing the effects of the degradation, sets an extraction function for extracting a desired frequency component from the degradation-removed data, and reconstructs RF data on the basis of the degradation-removed data and extraction function.</p> |
