Apparatus and method for radiation imaging

A radiation imaging apparatus comprising:

• a radiation source for irradiating an object;
• a radiation image detector for detecting a radiation image of said object, said radiation image detector having a radiation-receiving plane that receives radiation from said radiation source through said object;
• a shape information acquiring means for acquiring shape information that represents a shape of said object;
• and
• a shape information display means that displays said shape information such that it reproduces a position of said object as occurs when said shape information acquiring means has acquired said shape information, and
• a press plate that can be moved closer to or away from said radiation-receiving plane and which compresses said object against an object-supporting plane of said radiation image detector,
• wherein said shape information display means displays said shape information on said press plate.

A radiation imaging method, comprising:

• a first imaging step of taking a first radiation image of a first object and generating shape information which represents the shape of said first object;
• a display step of inverting said shape information and displaying inverted shape information such that it reproduces a position of said first object in said first imaging step;
• and
• a second imaging step of taking a second radiation image of a second object, wherein,
• in said first imaging step, said shape information is generated from said first radiation image of said first object, and
• said display step is a step of displaying said shape information on an object-supporting plane.

• said shape information is generated from said first radiation image of said first object, and
• said display step is a step of displaying said shape information on said press plate.
