System Requirements

  • Processor: Intel Core i3 or higher processer (or equivalent) minimum is recommended
  • 4 GB RAM minimum is recommended
  • Windows XP or higher version
  • Minimum 5 GB available hard drive space
  • Screen resolution of 1024 x 768 or greater for best results

Beam Data Requirements

The following data is required for the creation of a linac database. Please contact Oncology Data Systems, Inc. for a beam data checklist prior to sending linac data.

Photon Beams

  • Percent depth dose tables
  • Collimator output factors, split into collimator (Sc) and phantom (Sp) scatter factors
  • TMR tables (if available – these can be generated by ODS)
  • Central-axis wedge factors for physical wedges. We support three different configurations:
    • Central axis wedge factor by field size
    • Wedge factors by field size and depth
    • Wedge factor + wedge PDD
  • Off-axis profiles for open field
  • Off-axis profiles for physical wedges (in the gradient direction of the wedge)
  • Correction factors, if desired – these include items such as trays, breast boards, head holders, compensators, table attenuation, etc.
  • MLC leaf tip/transmission factors (IMRT/VMAT only)

Please note: For the VMAT Module, some additional small field information may be required, as well as electron density curves.

Electron Beams

  • PDD tables – only required if not using isodose line
  • Cone sizes and output factors
  • Virtual source distance
  • Non-standard distance factors, if needed
