Actual (reported)The purpose of this study is to test a new technology for obtaining x-ray images of your treatment fields when you are positioned on the treatment machine, to determine whether this new system is as reliable and easy to use as conventional systems.. These so-called portal images are normally taken on a weekly basis, prior to your radiation treatment. The new portal imaging system to be tested is designed to produce better quality images than are currently achievable, but with no additional dose or added treatment time.

Actual (reported)Obtain multiple (1-5) 3DCBIs on patients during the course of their radiation therapy treatments using a prototype megavoltage (MV) system and determine if the prototype imaging system is reliable and practical for routine clinical portal imaging.
conclusion of the study
For some patients, in addition to obtaining 1-5 MV conebeam scans, obtain 1-2 conebeam scans using a new kilovoltage conebeam imaging system
conclusion of the study
Compare the quality and utility of the MV and kV conebeam systems.
conclusion of the study
Prototype, third generation EPID based portal imaging system utilizing the MV approach.
Prototype, third generation EPID based portal imaging system utilizing the MV approach.
