X-ray apparatus and method of acquiring medical image thereof

An X-ray apparatus comprising:

• an X-ray emitter configured to emit X-rays to a target object;
• an X-ray detector configured to detect emitted X-rays that have passed through the object;
• at least one processor configured to control the X-ray emitter and the X-ray detector;
• and
• a memory connected to the at least one processor,
• wherein the memory is configured to store instructions which, when executed by the at least one processor, cause the at least one processor to:
• acquire an original radiation image of the target object from the X-ray detector;
• acquire a bone structure radiation image of a bone structure included in the target object from the acquired original radiation image using a learning network model, wherein the learning network model is trained to estimate a radiation image corresponding to a bone from a plurality of different radiation images;
• and
• acquire a medical image in which at least one portion of the bone structure is suppressed from the original radiation image using the bone structure radiation image,
• wherein the learning network model is further trained based on capturing condition information indicating at least one capturing condition corresponding to the plurality of different radiation images.
