3-DIMENSIONAL IMAGERY IN ONCOLOGY

Accurate 3D tumoral volume evaluation is now possible through the comb ined use and progress of computer graphics technics (3D reconstruction and visualization) and medical imagery (helicoidal TDM scanner). Spec ific organ and pathology oriented softwares can help answer rapidly to problems posed by oncologic praticians. A new decision support for di agnosis, therapy and follow-up is emerging. First results in liver tum ors and hepatic regeneration macroscopic biometrics are presented. Tum oral or organ volumic index will be usable in the follow-up. TNM stagi ng, external conformal radiotherapy for prostatic or brain tumors, dru gs cytolytic effects evaluation will take great advantage of these tec hnologies. 3D visualization and matching CT and MRI imagery can help c omputed assisted surgery.
