Registration apparatus, method, and program

A registration method, comprising:

• acquiring, from each of two different examinations including a plurality of imaging series including three-dimensional images each of which is configured to include a plurality of tomographic images, accessory information regarding the three-dimensional images;
• selecting one imaging series from each of the two examinations based on the accessory information;
• and
• performing registration between the three-dimensional images included in the imaging series of the two examinations based on images included in the selected imaging series and acquiring a result of the registration as a registration result between the two examinations.

A non-transitory computer readable recording medium storing a registration program causing a computer to execute:

• a step of acquiring, from each of two different examinations including a plurality of imaging series including three-dimensional images each of which is configured to include a plurality of tomographic images, accessory information regarding the three-dimensional images;
• a step of selecting one imaging series from each of the two examinations based on the accessory information;
• and
• a step of performing registration between the three-dimensional images included in the imaging series of the two examinations based on images included in the selected imaging series and acquiring a result of the registration as a registration result between the two examinations.

A registration apparatus according to the invention comprises:

• a memory that stores commands to be executed by a computer;
• and
• a processor configured to execute the stored commands, the processor executes:
• processing for acquiring, from each of two different examinations including a plurality of imaging series including three-dimensional images each of which is configured to include a plurality of tomographic images, accessory information regarding the three-dimensional images;
• processing for selecting one imaging series from each of the two examinations based on the accessory information;
• and processing for performing registration between the three-dimensional images included in the imaging series of the two examinations based on images included in the selected imaging series;
• and
• acquiring a result of the registration as a registration result between the two examinations.
