Abstract

The Varian Enhanced Dynamic Wedge is a dynamic modality implemented on Clinac 2100 C/D and 600 C linear accelerators in order to obtain wedge angles just by the sweeping of one of the secondary collimators (y1 or y2) across the field. The Segmented Treatment Tables of instruction define dose rate modification according to jaw position and the same tables are implemented on Cadplan treatment planning system. The EDW implementation supports standard wedge angles of 10°, 15°, 20°, 25°, 30°, 45° and 60°, and field dimensions up to 30 cm in the wedge direction. Before routine clinical use, dosimetric verifications are required to verify proper working of the modality and Cadplan calculation.
