1. An X-ray diagnostic apparatus comprising:
an X-ray tube configured to generate X-rays;
an X-ray detector configured to detect X-rays emitted from the X-ray tube and transmitted through a subject; and
processing circuitry configured to:
receive a designating operation related to a display mode of a target that is at least one of a region of the subject and an object inserted in the subject; and
change the display mode of the target in an X-ray projection image that is based on a detection result of the X-ray detector, the display mode being changed based on three-dimensional medical image data related to the subject, in accordance with the designating operation,
wherein the processing circuitry is configured to change the display mode of the target by applying a compensation to the detection result of the X-ray detector using an amount of X-ray attenuation that is calculated based on the three-dimensional medical image data or an X-ray attenuation coefficient that is calculated based on the three-dimensional medical image data, the X-ray attenuation caused by the target in an image capturing geometry of the X-ray diagnostic apparatus, the X-ray attenuation coefficient being that related to the target in an image capturing geometry of the X-ray diagnostic apparatus.
 
8. An X-ray diagnostic apparatus comprising:
an X-ray tube configured to generate X-rays;
an X-ray detector configured to detect X-rays emitted from the X-ray tube and transmitted through a subject; and
processing circuitry configured to:
receive a selecting operation for selecting a target for which a display mode is to be changed, from a region of the subject or an object inserted in the subject; and
change the display mode of the target in an X-ray projection image that is based on a detection result of the X-ray detector, the display mode being changed based on three-dimensional medical image data related to the subject,
wherein the processing circuitry is configured to change the display mode of the target by applying a compensation to the detection result of the X-ray detector using an amount of X-ray attenuation that is calculated based on the three-dimensional medical image data or an X-ray attenuation coefficient that is calculated based on the three-dimensional medical image data, the X-ray attenuation caused by the target in an image capturing geometry of the X-ray diagnostic apparatus, the X-ray attenuation coefficient being that related to the target in an image capturing geometry of the X-ray diagnostic apparatus.
