Elekta supports the clinic wishing to maintain their investment in an existing treatment planning system through an open systems philosophy. Alternatively, Elekta offers a choice of inverse planning solutions with PrecisePLAN®. Elekta PrecisePLAN® Using an aperture based IMRT technique PrecisePLAN® is able to offer the advantages of inverse planning while minimizing the complexities. This approach provides: - monitor unit and segment number efficiency
- intuitive intensity patterns, verifiable by traditional field placement methods
- no leaf direction restriction or approximations of fluence interpreter software.
Aperture based IMRT is an extension to 3-D conformal planning where geometric shaped apertures are created to cover target structure(s) and avoid organs at risk. Clinical protocol templates (including RTOG) can be loaded from a workflow manager that guides the user through the planning process. Scripting automates each step from contouring with 3-D margining, segment weight (monitor unit) optimization with the Cimmino algorithm, to output and DICOM RT PLAN export to Elekta Precise Treatment System™ for treatment delivery. | | Consortium developments Several of the Elekta IMRT International Consortium have established forward and inverse planning for IMRT. Thomas Jefferson University Hospital, Philadelphia, USA Here, optimization of weighting of the beams selected through a forward planning process in the clinical treatment of prostate cancer has been implemented as an easy way to achieve the therapeutic advantage of IMRT. For further information on this technique, see the AAPM presentation (James M. Galvin et al) title: Inverse Treatment Planning that Starts with a Rule-based Selection of Apertures - click for more. Universitaetsklinikum Tuebingen, Germany The Hyperion project group covers research topics including optimization algorithms, biological modelling, and fast Monte Carlo dose calculations - click for more. University of Maryland, Baltimore, USA A research program into the delivery of Intensity Modulated Arc Therapy (IMAT) has established excellent results using forward planning techniques for IMAT. The ability of IMAT to conform dose to C-shaped targets and to avoid sensitive structures, when treating sites such as prostate or vertebral bodies, is a major clinical improvement on today’s techniques.
