RADIOGRAPHIC APPARATUS
Document Type and Number:
Japanese Patent JP2012061148
Kind Code:
A
Abstract:

To provide a radiographic apparatus, capable of acquiring a clear image from which scattered radiation is removed by a further simple structure.

The radiographic apparatus includes a shield 5 which moves relative to an X-ray tube 3. An original image P0 is generated while changing the position of the shadow of the shield 5. An intermediate image generation unit 11 generates a dark image P2 in which only the shadow of the shield 5 is taken and a bright image P3 in which only the part other than the shadow of the shield 5 is taken. Only a scattered radiation component is taken in the dark image P2, while the scattered radiation component is superposed on a fluoroscopic image of a subject in the bright image P3. A removal unit 15 removes the scattered radiation component superposed in the bright image P3 based on the dark image P2. According to this, the radiographic apparatus capable of acquiring a clear image from which scattered radiation is removed by a simple structure can be provided.
