متن کامل'Tongue-and-groove' effect in intensity modulated radiotherapy with static multileaf collimator fields.
The 'tongue-and-groove problem' in step-and-shoot delivery of intensity modulated radiotherapy is investigated. A 'tongue-and-groove' index (TGI) is introduced to quantify the 'tongue-and-groove' effect in step-and-shoot delivery. Four different types of leaf sequencing methods are compared. The sliding window method and the reducing level method use the same number of field segments to deliver...
متن کاملA method for determining multileaf collimator transmission and scatter for dynamic intensity modulated radiotherapy.
The main purpose of this work is to demonstrate a practical means of determining the leaf transmission and scatter characteristics of a multileaf collimator (MLC) pertinent to the commissioning of dynamic intensity modulated radiotherapy, especially for the sweeping window technique. The data are necessary for the conversion of intensity distributions produced by intensity-modulated radiotherap...
متن کامل[Intensity-modulation radiotherapy using independent collimator: algorithm study].
To investigate algorithms for independent collimator (IC) to modulate beam intensity distributions. Field-setting sequences were determined for three clinical intensity distributions with two forward algorithms. The delivery order of all fields in the sequences was optimized in order to minimize the overall jaw-moving time. Suppose treatments were performed with Varian 600C, delivery time was c...
متن کاملIndependent monitor unit calculation for intensity modulated radiotherapy using the MIMiC multileaf collimator.
A self-consistent monitor unit (MU) and isocenter point-dose calculation method has been developed that provides an independent verification of the MU for intensity modulated radiotherapy (IMRT) using the MIMiC (Nomos Corporation) multileaf collimator. The method takes into account two unique features of IMRT using the MIMiC: namely the gantry-dynamic arc delivery of intensity modulated photon ...
