Technical Specifications

Forward Conformal Plan
Can arrange photon treatment, electron treatment, and also compounding treatment in forward conformal plan module. Block, aperture, MLC, wedge and bolus can be used for planning. Dose Volume Histograms (DVH) can also be calculated.

Inverse Step-and-Shoot / Sliding IMRT Plan
Include Intensity-map based optimization and Aperture based optimization methods. 3D compensator and auto beam selection can also be arranged.

Simple, Easy, Seamless and Accurate
Both the 3D fast full scatter Pencil Beam convolution algorithm for photon beam calculations and the 3D pencil beam algorithm for electron calculation offer fast dose calculations. Adding beams from the standard beam library or a user defined template beam library along with the automatic definition of the target isocenter makes TPS accurate as well as simple and easy to use.

Sliding ARC IMRT and Delivery Package
TPS provides a complete package of planning modalities including conformal, forward and inverse planning techniques and Dynamic Sliding ARC with easy to use planning tools. The final plan can be easily exported to our Dynamic Multi-leaf Collimator (MLC). Conformal, Step & Shoot and Sliding Window IMRT, and Sliding ARC IMRT delivery protocols are supported by planning and export functions. Sliding ARC IMRT can deliver a typical treatment plan within 2 to 5 minutes. As a standard feature, the TPS also includes a DICOM RT import and export module providing communications to most RT devices and record and verify (R&V) networks.
