The set of 3D parametric data includes a plurality of voxels in 3D space each associated with at least one parametric value, and the set of 2D image data includes information about a known camera position and a known camera orientation at which the 2D image was obtained. A graphical representation is generated of the parametric values of the voxels corresponding to a viewing surface in 3D space. A virtual 2D view of the viewing surface is determined. The 2D image is displayed registered with the graphical representation of the parametric values of the voxels corresponding to the virtual 2D view.

摘要： An apparatus and method obtain an image of an object from a first radiation source in the presence of a second radiation source. The first radiation source is directed at a first side of the object while the second radiation source is directed at the second side of the object. At least one portion of the radiation is detected at the second side of the object. A first signal is produced based on the at least one portion of detected radiation. The first signal has a first radiation component and a second radiation component. At least one other portion of radiation at the second side of the object is filtered and then detected. A second signal is produced based on the detected filtered radiation. The second signal has at least one of a filtered first radiation component and a filtered second radiation component. Then a third signal is produced from the first and second signals. The third signal is a representation of a first radiation component.
