pubmed-article:17935807 | pubmed:abstractText | 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. | lld:pubmed |
