PROBLEM TO BE SOLVED: To form an ultrasonic image by which a blood running condition in its vessel can be expressed in a three-dimensional manner. SOLUTION: A voxel space 100 is sliced into a plurality of blocks to execute a predetermined operation for each block. An intermediate image 102 is generated to show a blood vessel only for each block. The intermedium images 102 are superposed giving priority to the ones closer to a viewpoint side while being weighed by a depth queuing method. By doing this, a superposed image 104 is formed. By matching a vision with the direction of an ultrasonic beam, the processing becomes faster, and in this case, an inversely binarizing or a depth queuing processing can be executed for each unit of vision. |
