3D-CRT PLANNING

All the manual and automatic tools you need to create high-quality 3D-CRT plans in an efficient and consistent way.

3D-CRT planning

RayPlan supports conventional 3D-CRT forward treatment planning, with manual and automatic tools for conformal treatment using treat-and-protect, beam weighting, wedges, and more.

Modern inverse planning techniques are also available for creating conventional 3D-CRT plans. These plans can be automatically optimized with respect to any combination of segment shapes, segment monitor units, collimator, gantry and couch angles. This makes plan creation faster and more consistent.


RayPlan supports conformal planning of 3D-CRT, conformal arc or static arc treatment techniques.

  • Beam aperture with MLC and blocks
  • Shielding blocks
  • Circular cones
  • Tools for drawing and manipulating apertures in BEV
  • Automatic computation of apertures based on target ROI and OAR
  • Merging of beams for field-in-field planning
  • Direct optimization of 3D-CRT treatment parameters, such as leaf position, beam weight, wedge angle, wedge fraction, collimator angle, gantry angle and couch angle
