Software for automatic checks of isocenter geometry and laser alignmentEvaluates starshots with film or 2D-ARRAY seven29For use with ISOCHECK Isocenter Test DeviceScanning software with TWAIN interface includedIsoCheck is a software package for automatic starshot analysis. It checks size and position of the isocenter sphere and its distance to the laser cross. The result can be exported in an ASCII xml file and printed. IsoCheck software supports direct control of various scanner types as well as scanners with TWAIN interface. For film irradiation the ISOCHECK isocenter test device can be used. All common file formats including DICOM can be read. Also starshots acquired with the 2D-ARRAY seven29 can be easily loaded and evaluated.
