To register a position and an angle of a scanning surface of an ultrasound probe easily and accurately. A phantom including two or more wires stretched in a non-parallel manner is disposed in a real space in which a position detection sensor is disposed. An ultrasound probe, to which a probe position detection marker is attached, is moved on the phantom in a parallel manner while keeping an orientation of a main plane of the ultrasound probe constant. Two or more ultrasound images of the phantom are acquired while detecting a position of the probe position detection marker in the real space with the position detection sensor. Positions of cross-sectional images of the two or more wires included in each of the two or more ultrasound images are obtained. A relation between the position of the probe position detection marker in the real space and orientations and positions of the captured ultrasound images in the real space is calculated based on a relation between the obtained positions of the cross-sectional images. The calculated relation as probe coordinate transformation information is registered in a storage unit.

For three-dimensional segmentation from two-dimensional intracardiac echocardiography imaging, the three-dimension segmentation is output by a machine-learnt multi-task generator. Rather than the brute force approach of training the generator from 2D ICE images to output a 2D segmentation, the generator is trained from 3D information, such as a sparse ICE volume assembled from the 2D ICE images. Where sufficient ground truth data is not available, computed tomography or magnetic resonance data may be used as the ground truth for the sample sparse ICE volumes. The generator is trained to output both the 3D segmentation and a complete volume (i.e., more voxels represented than in the sparse ICE volume). The 3D segmentation may be further used to project to 2D as an input with an ICE image to another network trained to output a 2D segmentation for the ICE image. Display of the 3D segmentation and/or 2D segmentation may guide ablation of tissue in the patient.
