ULTRASONIC DIAGNOSTIC APPARATUS AND ULTRASONIC DIAGNOSTIC IMAGE RENDERING METHOD

摘要

The ultrasonic diagnostic apparatus is equipped with: a gradient calculating section that calculates gradients of the volume data voxel values; a feature calculating section that calculates the feature values of the voxels on the basis of the gradients and the direction of the ultrasonic beam and calculates a feature space on the basis of the feature values; an object-voxel determining section that determines the voxels that correspond to the object on the basis of the feature space; a voxel removing section that removes voxels that are closer to the probe than the object; and an ultrasonic image generating unit that generates ultrasonic images that correspond to the object from the volume data from which the voxels closer to the probe have been removed.
