2D/3D image registration with the ImagingRing

We investigate the potential of the ImagingRing system in the context of 2D/3D image registration which is especially required in intrafractional position verification and online treatment guidance, because 3D image acquisition is too slow and would deposit too much dose in the patient if continuously involved.

One problem that is often encountered in 2D/3D registration is the presence of high-contrast structures such as bone in front of the target which degrades the accuracy of the spatial alignment. Hereby we aim at adequately using dual-energy radiographs to virtually remove these structures and, thereby, improve 2D/3D registration robustness.
