Abstract: A high-definition guide image for supporting a procedure that uses an X-ray fluoroscopic image is generated from 3D images taken in advance by a CT device and an MRI device, and the generated image is displayed. A parameter value is acquired from the parameters set in an X-ray imaging device upon taking the fluoroscopic image. After performing registration between the 3D CT image and the 3D MRI image, using the parameter value of the X-ray imaging device, the direction of light passage of the cone beam is set on each of the 3D CT image and the 3D MRI image, and 2D projected images are generated therefrom respectively. Then, the generated 2D projected images are superimposed and the superimposed image is displayed as the guide image.

Abstract: A radiographic imaging apparatus acquires a plurality of two-dimensional pickup images taken at different angles and a three-dimensional image of a processing target imaged in advance. Two-dimensional calculated projection images are generated from the three-dimensional image, respectively, in association with the two-dimensional pickup images. A characteristic region indicates a treatment instrument represented in the two-dimensional pickup image. The two-dimensional pickup image is aligned with the calculated projection image. A deformation amount of the processing target in the two-dimensional pickup image is calculated by comparing the two-dimensional pickup image with the calculated projection image, and a position of the characteristic region is corrected. A three-dimensional position of the characteristic region is calculated and corrected on the basis of anatomical structure information of the processing target.

Abstract: Visualizing a deformation amount or displacement amount of a region of interest in therapy rendered in an image upon aligning images used in radiation therapy allows for enhancing an accuracy of alignment. In a positioning system 104, an image processing unit 201 calculates a deformation parameter using a non-rigid registration method for a region of interest having been set by a treatment planning device 101 based on a treatment plan CT image and three-dimensional tomographic image imaged for bed positioning and calculates a displacement amount parameter for a region extracted using a region extraction method. The image processing unit 201 calculates a positioning parameter representing a displacement amount of a bed based on the calculated deformation parameter and displacement amount parameter and displays the respective parameters together with an alignment image, thereby allowing for confirmation of the deformation amount and displacement amount.
