The effect of respiratory motion on electronic portal imaging device dosimetry. [PDF]
J Appl Clin Med Phys, 2019 AbstractThere is an increasing need to develop methods for in vivo verification of the delivery of radiotherapy treatments. Electronic portal imaging devices (EPID's) have been demonstrated to be of use for this application. The basic principle is relatively straightforward, the EPID is used to measure a two‐dimensional (2D) planar exit or portal dose ...
