Isocenter QA software for determining the radiological rotational isocenters of a LINAC by analysing EPID imagesExport to Track-it QA data management software for trending and reportingDetermines the radiological rotational isocenters of aLINAC by analysing EPID imagesShows several levels of information: Combined and per image analysisTrends over timeThe software IsoCheck epid helps the medical physics expert to ensure the correct positioning of the LINAC radiological rotational isocenters. This is done by comparing the position of a high density ball (ISOBALL T42037) aligned to the treatment room lasers to the center of a radiation field irradiating this ball. The results can be displayed visually or numerically. Trends over time can be displayed in a separate QA statistics tab.
