摘要:
An X-ray imaging apparatus includes a substantially C-arm, a support mechanism which rotatably supports substantially the C-arm, a rotation driving unit which drives rotation of substantially the C-arm, an X-ray tube mounted on substantially the C-arm, an X-ray detector mounted on substantially the C-arm, and a control unit which controls at least one of the rotation driving unit and an imaging control unit to make intervals between a plurality of contrast-enhanced images shorter than intervals between a plurality of mask images by changing a rotational speed of substantially the C-arm before and after injection of a contrast medium.
摘要:
A 3D image processing apparatus comprises a storing unit storing mask images corresponding to projection directions associated with a subject contrast images corresponding to the projection directions, a subtracting unit generating subtraction images by subtracting the mask images from the contrast images, a reconstruction unit reconstructing first volume data from the mask images and reconstructs second volume data from the subtraction images, an image processing unit generating a first 3D image representing a bone structure and/or a soft tissue structure from the first volume data, and generates a second 3D image representing a contrasted blood vessel from the second volume data, an image synthesizing unit generating a synthetic image by synthesizing the first 3D image with the second 3D image, and a displaying unit displaying the synthetic image.
摘要:
A 3D-image processing apparatus comprising a first acquisition device, a second acquisition device, and a computing unit. The first acquisition device acquires displacement information about first 3D-imaging data and second 3D-imaging data different from the first 3D-imaging data. The first 3D-imaging data represents one of three-dimensional images different in diagnostic mode regarding a subject. The second acquisition device acquires displacement information about the second 3D-imaging data and a third 3D-imaging data different from the first and second 3D-imaging data. The computing unit obtains displacement information about the first 3D-imaging data and the third 3D-imaging data, from the displacement information acquired by the first and second acquisition devices.
