Impact of Multileaf Collimator Configuration Parameters on the Dosimetric Accuracy of 6-MV Intensity-Modulated Radiation Therapy Treatment Plans
The purpose of this study was to evaluate the impact of selected configuration parameters that govern multileaf collimator (MLC) transmission and rounded leaf offset in a commercial treatment planning system (TPS) (Pinnacle3, Philips Medical Systems, Andover, MA, USA) on the accuracy of intensity-modulated radiation therapy (IMRT) dose calculation. The MLC leaf transmission factor was modified ...
متن کاملAn Automated Image-based Method for Multi-Leaf Collimator Positioning Verification in Intensity Modulated Radiation Therapy
Intensity Modulated Radiation Therapy (IMRT) is an innovative, three-dimensional conformal radiation treatment that can deliver highly focused and precisely shaped radiation to a tumor site through the use of the Multi-Leaf Collimators (MLC). A crucial step in IMRT procedure is the verification of MLC positioning to assure the accuracy of radiation treatment delivery. In this paper, we have dev...
متن کاملDesign, Simulation and Manufacture of a Multileaf Collimator to Confirm the Target Volumes in Intensity Modulated Radiation Therapy
Introduction: Intensity modulated radiation therapy (IMRT) is one of the cancer treatment methods. It is important to selectively aim at the target in this way, which can be performed using a multileaf collimator (MLC). Materials and Methods: In order to specifically irradiate the target volume in radiotherapy to reduce the patient absorbed dose, the use of multileaf collimator has been investi...

متن کاملDetermination of depth and field size dependence of multileaf collimator transmission in intensity‐modulated radiation therapy beams
Intensity-modulated radiation therapy (IMRT) plans for the treatment of large and complex volumes may contain a relatively large contribution from multileaf collimator (MLC) transmission. In such cases, comprehensive characterization of direct and scatter MLC transmission is important. We designed a set of tests (open beam, closed static MLC, and dynamic MLC gap) to determine dosimetric MLC pro...
