Intra-fractional movements of the tumor can cause large geometrical errors. This is especially true for tumors in the lung and the liver, it has been shown that even the prostate can move considerably during the treatment. If these geometrical errors are not handled correctly they can result in critical dosimetric errors. This may result in the tumor volume receiving too little dose to achieve tumor control whilst organs at risk can rec ve too high dose.

The Delta4 HexaMotion 6D motion platform accuracely replicates the actual tumor motion. The QA is based on how the real tumor is moving. The motion patterns both for the tumor and the patient can be imported from your motion management system and the same movement cycle is then exactly with the Delta4 Phantom . The phantom is positioned quickly and within sub-millimeter accuracy. The Delta4 HexaMotion 6D motion platform is used together with the Delta4 Phantom to provide a full analysis of the dosimetric effect of tumor respiratory motion. The true delivery of the prescription dose can be studied...
