Image processing apparatus for C-arm

1. An image processing apparatus for a C-arm, comprising:

a movement control unit which moves a C-arm which irradiates a radiation onto a bone of a subject located on a table and detects the radiation which penetrates the bone to generate a projection image for the bone, along a predetermined route, wherein the predetermined route is a route set to move the C-arm along a front and rear direction of the table;

an image acquiring unit which acquires a plurality of projection images generated by the moving C-arm at every predetermined interval;

an analysis unit which analyzes physical feature information of the subject located on the table; and

an image processing unit which generates a combined projection image in which the plurality of acquired projection images is combined,

wherein the predetermined route is set to be different depending on the physical feature information of the subject which is analyzed by the analysis unit, and

wherein the predetermined interval is an interval at which a continuous panoramic image is generated by connecting the plurality of acquired projection images.

2. The image processing apparatus for a C-arm according to claim 1 , wherein a size of the projection image is determined by a size of a radiation detector which is provided at one end of the C-arm to detect radiation which penetrates the bone and a size of the combined projection image is larger than a size of each of the plurality of projection images.

3. The image processing apparatus for a C-arm according to claim 1 , wherein a plurality of pressure sensors is disposed on a top surface of the table with an interval and the analysis unit calculates a length of a spine as the physical feature information of the subject by analyzing a plurality of pressure sensing values acquired from the plurality of pressure sensors.

4. The image processing apparatus for a C-arm according to claim 1 , wherein the analysis unit further determines a shape of a spine as the physical feature information of the subject by analyzing the projection image acquired by the image acquiring unit and determines a position of the C-arm with respect to the table in consideration of the determined shape of the spine and the predetermined route is set to include the determined position of the C-arm.

5. The image processing apparatus for a C-arm according to claim 4 , wherein the analysis unit determines a curved shape of a rear end of the spine corresponding to a first region for a front and rear direction of the table as the shape of the spine, based on the first region which is a region corresponding to the spine identified from a first projection image by analyzing the first projection image acquired by the image acquiring unit and determines the position of the C-arm for acquiring a second projection image acquired subsequently to the first projection image in consideration of the determined shape of the spine and an area of a second region which is a region other than the spine identified from the first projection image.

6. The image processing apparatus for a C-arm according to claim 4 , wherein the analysis unit determines a position of the C-arm corresponding to each of remaining projection images for acquiring the remaining projection images other than a first projection image among the plurality of projection images and

the position of the C-arm corresponding to any one projection image among the remaining projection images is determined in consideration of a shape of a spine determined by an image analysis of a previous projection image acquired before any one projection image and an area of a region other than a spine.

7. The image processing apparatus for a C-arm according to claim 1 , wherein the image processing unit displays the generated combined projection image on a display unit and when a user input is performed on any one point on the combined projection image displayed on the display unit, controls an operation of a laser irradiating unit provided at one end of the C-arm to irradiate laser onto a position on a surface of a body of the subject corresponding to any one point.

8. An image processing apparatus for a C-arm, comprising:

a movement control unit which moves a C-arm which irradiates a radiation onto a bone of a subject located on a table and detects the radiation which penetrates the bone to generate a projection image for the bone, along a predetermined route;

an image acquiring unit which acquires a plurality of projection images generated by the moving C-arm at every predetermined interval; and

an image processing unit which generates a combined projection image in which the plurality of acquired projection images is combined,

wherein the predetermined interval is an interval at which a continuous panoramic image is generated by connecting the plurality of acquired projection images, and

wherein the image processing unit displays the generated combined projection image on a display unit and when a user input is performed on any one point on the combined projection image displayed on the display unit, controls an operation of a laser irradiating unit provided at one end of the C-arm to irradiate laser onto a position on a surface of a body of the subject corresponding to any one point.
