Real-time dynamic MLC tracking for inversely optimized arc radiotherapy.
BACKGROUND AND PURPOSE Motion compensation with MLC tracking was tested for inversely optimized arc radiotherapy with special attention to the impact of the size of the target displacements and the angle of the leaf trajectory. MATERIALS AND METHODS An MLC-tracking algorithm was used to adjust the MLC positions according to the target movements using information from an optical real-time posi...
متن کاملValidation of dynamic MLC-controller log files using a two-dimensional diode array.
Intensity-modulated radiation therapy (IMRT) delivered with multi-leaf collimator (MLC) in the step-and-shoot mode uses multiple static MLC segments to achieve intensity modulation. For typical IMRT treatment plans, significant numbers of segments are delivered with monitor units (MUs) of much less than 10. Verification of the ability of the linear accelerator (linac) to deliver small MU segmen...
متن کاملAssessment of MLC tracking performance during hypofractionated prostate radiotherapy using real-time dose reconstruction
By adapting to the actual patient anatomy during treatment, tracked multi-leaf collimator (MLC) treatment deliveries offer an opportunity for margin reduction and healthy tissue sparing. This is assumed to be especially relevant for hypofractionated protocols in which intrafractional motion does not easily average out. In order to confidently deliver tracked treatments with potentially reduced ...
متن کاملIn vivo dose verification using using an amorphous silicon flat panel-type imager (a-Si EPIDs)
Introduction: Electronic portal imaging devices (EPIDs) could be used to dose verification of radiotherapy treatment plans. In vivo dose verification is performed to reduce differences found between dose delivered to the patient and the prescribed dose. The aim of this study was to perform a fast and efficient technique for the verification of delivered dose to the patient usin...
