Patent ID: 7697779

Claim:
An ultrasonic image processing apparatus allowing an ultrasonic image of an inspection object to be displayed using echo data in a three-dimensional region, the apparatus comprising: an image constructing section for constructing a three-dimensional image based on the echo data; an image operation input section for performing an operation to change the display state of the constructed three-dimensional image; and an image display state changing section for changing the display state of the three-dimensional image that has been constructed based on input information inputted by the image operation input section, wherein the image constructing section comprises a maximum intensity detecting section for detecting a maximum intensity of echo data with respect to the all echo data in a first frame; a reference intensity calculating section calculating a reference intensity in correspondence with the detected maximum intensity; and a boundary position calculating section for calculating a distance from an ultrasonic wave transmission/reception position to a position at which echo data becomes not less than the reference intensity and multiplying the distance by a factor set for the distance to calculate a boundary position.
