The TomoTherapy Treatment Planning Station provides three intuitive tabs to guide the planning process for creation of sophisticated IMRT plans for both simple and complex cases. Treatments are prescribed and plans optimized based on diagnostic CT and anatomical structure data that includes the specified dosimetric goals and constraints.

Following definition of prescription and constraints, the Optimization Cluster efficiently optimizes the weight of the tens of thousands of beamlets used in a typical TomoTherapy radiation treatment fraction. (Each beamlet weight corresponds to the “opening time” of a single leaf in the MLC at a given stage of delivery.) Three-dimensional dose distributions and dose-volume histograms (DVHs) are available as analysis tools to either accept or modify—and re-optimize—the planned dose.

This simple process is the same for all plans—whether using TomoHelical or TomoDirect, whether planning a prostate treatment or a total marrow irradiation treatment.

The TomoTherapy System offers a number of treatment planning tools – such as Remote Planning, Planned Adaptive™ software and VoLO™ Technology – that improve efficiency and accuracy of the treatment planning process.
