Multimodality Simulation is the most accurate process available to localize, define and reconstruct a patient's tumor in 3 dimensions.

Vital to the process of virtual simulation is the imaging device with a flat table top and the RT Planning Software with virtual simulation option, interfaced to the precision marking system with moving lasers.

A modern CT scanner can delineate target volumes and organs at risk with high precision. The other imaging modalities, like PET, SPECT and MRI add specific informations to localize the tumor and define the target.volume. The capabilities of the scanner are enhanced, when a DORADO laser marking system is part of the scanner configuration. This laser system projects and marks the correct treatment set-up directly on the patient's skin, eliminating the need of a conventional simulator.

The treatment plans are automatically transferred via computer network to the DORADO system, to be projected on the patient's skin. Precision marking enables the Radiation Therapist to reproduce the treatment set-up each day with a high degree of accuracy.
