Testing of dynamic multileaf collimation

Abstract: It has been shown that intensity-modulated fields have the potential to deliver optimum dose distributions, i.e., high dose uniformity in the target and lower doses in the surrounding critical organs. One way to deliver such fields is by using dynamic multileaf collimation (DMLC). This capability is already available in research mode on some treatment machines. While much effort has been devoted to developing algorithms for DMLC, the mechanical reliability of this new treatment delivery mode has not been fully… Show more

“…The authors compared these dose profiles with the profiles calculated using Eclipse TPS for the value of the DLG previously determined from ion chamber measurements in the sweeping gap configuration (13) . The actual value of the DLG used in the calculation is not explicitly stated, other than referred to by Chui et al (14) and a range of numbers published by Van Esch et al (13) …”

“…Our experience with the Varian MLC and the experience from other centers (Memorial Sloane Kettering Cancer Center, New York, and Charite Hospital, Berlin) led us to decide to use dynamic delivery techniques for our first IMRT treatments. There are several excellent references discussing various individual aspects of IMRT which cover commissioning measurements, 1 , 2 planning techniques, 3 , 4 and treatment delivery quality assurance (QA) 5 8 Our intention in this paper is to provide a description of the procedures we undertook, from the commissioning of a commercially available inverse planning system (CadPlan/Helios, Varian Medical Systems, Palo Alto, CA), to routine treatment of prostate and pelvic nodes.…”
