Fiducial-based quantification of prostate tilt using cone beam computer tomography (CBCT)

Radiother Oncol. 2007 Nov;85(2):247-50. doi: 10.1016/j.radonc.2007.09.008. Epub 2007 Nov 1.


Translation-dependent prostate tilt was quantified with fiducial-based cone beam CT. Moderate anterior displacements (<5mm) of the prostate induce an anterior tilt, while a strong anterior displacement is accompanied by a more complex movement and can result in a backward tilt. Posterior movement resulted in a systematic backward tilt of about 1 degrees /mm.
