The dosimetric verification of TomoTherapy Hi-Art is easily performed with Delta4. The whole QA process is very simple and straight forward. In just one single run the complete 3D dose distribution is acquired .
Delta4 uses a unique 4D time resolution, so that for the complete delivery sequence Delta4 acquires the dose from each detector and for each individual dose pulse. Data can then be accessed for refined analysis.
- Real 3D dose measurements in th Target region.
- Cylindrical phantom gives isotropic characteristics in TomoTherapy.
- Complete delivery sequence verification with time resolution.
- Export measured data to the Hi-Art software.

"With the current push to generate very precise dose distributions in all three spatial dimensions, the Delta4 system is an innovative device for addressing volumetric delivery quality assurance for highly conformal treatment modalities such as the TomoTherapy™ HiART™. The geometry, dual orthogonal detector planes, and nature of the dosimeters enhance the applicability of the Delta4 system to special treatment techniques such as SBRT. The capability of measuring high dose per fraction treatments and verifying the radiation delivery from non-coplanar angles sets the system apart from single measurement plane devices."
