Radiation image processing device, radiation image processing method, and radiation image processing program

A radiation image processing method executed by a computer, the radiation image processing method comprising:

• acquiring at least one two-dimensional image including a spine of a subject during surgery on the subject;
• deriving a spine image in which the spine of the subject is emphasized based on the at least one two-dimensional image;
• extracting a two-dimensional target vertebra that is a target of registration from the two-dimensional image;
• and
• registering the two-dimensional target vertebra with a three-dimensional target vertebra that is a target of the registration, the three-dimensional target vertebra being extracted from a three-dimensional image including the spine of the subject acquired before the surgery on the subject.

A non-transitory computer-readable storage medium that stores a radiation image processing program causing a computer to execute a procedure comprising:

• acquiring at least one two-dimensional image including a spine of a subject during surgery on the subject;
• deriving a spine image in which the spine of the subject is emphasized based on the at least one two-dimensional image;
• extracting a two-dimensional target vertebra that is a target of registration from the two-dimensional image;
• and
• registering the two-dimensional target vertebra with a three-dimensional target vertebra that is a target of the registration, the three-dimensional target vertebra being extracted from a three-dimensional image including the spine of the subject acquired before the surgery on the subject.
