Witryna18 cze 2015 · IMRT is when the Multileaf Collimator (MLC) is introduced. So you have a step-and-shoot option, where the MLC is static during treatment, and then the sliding window technique where you can move the collimators real time during treatment. Is this correctly understood ? WitrynaIMRT dose plans were inversely-optimized using appropriate constraints with the Helios tool on a Varian Eclipse system. Once the optimal fluences were calculated, different … Witryna29 maj 2014 · To demonstrate a method for what-you-see-is-what-you-get multi-criteria Pareto surface navigation for step and shoot IMRT treatment planning. Methods: We show mathematically how multiple sliding window treatment plans can be averaged to yield a single plan whose dose distribution is the dosimetric average of the averaged … philips weighing machine
