Claim 5:
6. An apparatus for calculating a coronary artery calcium score, the apparatus comprising:
processing circuitry configured to:
acquire a target image for a coronary artery and myocardium before contrast enhancement,
identify the coronary artery included in the target image by using an artificial neural network, and
calculate a coronary artery calcium score based on the identified coronary artery,

wherein the artificial neural network is trained based on a training database generated via alignment between a pre-acquired image of a coronary artery and myocardium before contrast enhancement and a pre-acquired image of a coronary artery and myocardium after contrast enhancement, and
wherein the processing circuitry is configured to:
when identifying a calcified region in the target image, identify a first region corresponding to the identified coronary artery in the identified calcified region, and calculate the coronary artery calcium score for the first region, and
when identifying a coronary artery region in the target image, identify a second region corresponding to a calcified region in the identified coronary artery region, and calculate the coronary artery calcium score for the second region.
