We describe our preliminary experience with a beta-test version of the Lek-sell Gamma Plan (LGP) treatment planning system. During this testing phase we used the LGP system to find an acceptable treatment plan and then transferred coordinates to the KULA system for final calculation. We find that the LGP system offers a fast way of optimizing shot placement and weighting, especially for complex treatments. The ability to display many MR and CT images on screen and to superimpose isodose lines on these images, as soon as the dose distribution has been calculated, allows adjustments to be made more rapidly than with the plotting approach used by the KULA system. This software is in beta-test. and is undergoing modification. Problems relating to our hardware configuration have been addressed with a newer workstation specified for the production system.
