Title:
DEVIATION DETECTION DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/087674
Kind Code:
A1
Abstract:
A first acquisition unit 22 acquires stent regions As1, As2 from three-dimensional images G1, G2, respectively. A second acquisition unit 23 acquires blood vessel regions Av1, Av2 from the three-dimensional images G1, G2, respectively. An alignment unit 24 aligns the blood vessel regions Av1, Av2 vis-à-vis the three-dimensional images G1, G2, respectively, and acquires a first alignment result. A deviation information acquisition unit 25 acquires deviation information that indicates deviation between the three-dimensional images G1, G2 of a stent 31 relative to a blood vessel 32 on the basis of the stent regions As1, As2 vis-à-vis the three-dimensional images G1, G2 and a deformation vector Vm1 which is the first alignment result.
