TomoTherapy® Calculations

RadCalc’s Tomo module* provides support for the following TomoTherapy® features:

o TomoHelical deliveries
o TomoDirect deliveries
o TomoEDGE dynamic jaws

RadCalc’s calculations contain the following information:

o Prescriptions for documentation purposes
o One or more beams as imported from the TPS

RadCalc compares:

o Time calculations versus imported Plan Time
o Dose to multiple calculation points

RadCalc displays:

o 2D or 3D visualization of imported patient structures
o Sinogram
o Individual control points illustrating leaf open times

The RadCalc Process:

o Import plan and structures via DICOM
o Specify calculation points if not imported
o Compute the dose

Computation method:

o Measured or modeled PDD and Scp factors may be used
o Profile data is modeled via the weighted sum of three Gaussian distributions
o Ray tracing is performed through the structures to determine the depth and effective depth.  Each control point is decomposed into a set of finite beamlets with an  appropriate weighting such that their summation reproduces the imported sinogram for the control point
