Patent ID: 11941825
Assignee: CANON MEDICAL SYSTEMS CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 17:
18. A medical image processing method comprising:
receiving first volume data and second volume data;
determining a first symmetry plane for the first volume data and a second symmetry plane for the second volume data; and
conducting a registration of the first volume data and the second volume data based on the first symmetry plane and the second symmetry plane, wherein
conducting the registration comprises an alignment procedure and a constrained registration procedure, and
the alignment procedure comprises determining:
a first translation corresponding to a first direction;
a second rotation angle having a rotational axis corresponding to a second direction, wherein the second direction is orthogonal to the first direction; and
a third rotation angle having a rotational axis corresponding to a third direction, wherein the third direction is orthogonal to the first direction and to the second direction.
