Method for ascertaining the three-dimensional volume data, and imaging apparatus |
摘要 |
An imaging apparatus has a capture device for capturing 1D or 2D image data. A position and/or orientation for a moving section of an examination object is captured, for example using a measuring device, for a plurality of capture times for the image data. A computation device reconstructs 3D volume data from the image data based on projection parameters and based on the position and/or orientation of the moving section of the examination object. |

1. A method of determining 3D volume data of an examination object from a plurality of sets of 1D or 2D image data of the examination object, the method comprising:
with a detector, acquiring the plurality of sets of 1D or 2D image data; with a measuring device, determining positional data for at least one moving section of the examination object indicating a position and/or an orientation of the at least one moving section of the examination object for a plurality of capture times for the image data; and with a computation device, reconstructing the 3D volume data from the plurality of sets of image data based on the positional data indicating the position and/or the orientation of the at least one moving section and based on a plurality of projection parameter sets, wherein each projection parameter set is assigned to a set of image data and indicates pixel coordinates of the set of image data in which voxel coordinates of voxels of a measuring chamber are depicted. |
