This White Paper describes the Philips MRCAT (Magnetic Resonance for Calculating ATtenuation) solution for an MR-only based dose planning approach for external beam radiation therapy (EBRT).
Highly targeted treatment planning is at the foundation of successful
radiotherapy. With its superb and tunable soft-tissue contrast, MRI has in
recent years emerged as an imaging modality to drive delineation accuracy
of targets and organs at risk. With the introduction of the first commercially
available MR-only simulation package, Philips continues to pave the
way for the adoption and implementation of MRI in radiation treatment
planning. Philips MR-only simulation offers a single-modality approach
that provides both excellent soft-tissue contrast for target delineation
and density information for treatment planning for prostate cancer.
