Claim Text:
1. An ultrasonic diagnostic apparatus, comprising: a probe that transmits and receives ultrasound; a transmitter/receiver section that controls the probe to thereby obtain a reception signal of ultrasound; a filter processing section that applies filter processing to frame data obtained based on the reception signal of ultrasound along an arrangement direction of a plurality of frames; and an image forming section that forms an ultrasonic image based on the frame data having been subjected to the filter processing, wherein the filter processing section applies a high-pass filter, having an offset level set in accordance with a depth within a frame, to frame data at the depth, thereby performing the filter processing, and wherein the filter processing section applies a high-pass filter having an offset level set to a higher level as the depth within a frame is greater and having characteristics closer to characteristics of an all-pass filter as the depth within a frame is greater.
