Additionally, we’ll compare the time necessary for manual adjustments of the ROI on the treatment unit with the reason behind these adjustments. Material/Methods: Defining the ROI for the use of SGRT in the department is a separate task performed by a designated team of 10 RTTs in the preparation of the treatment plan for each patient eligible for positioning with this technique. From the 1 st of august 2024 until the 5 ft of September 2024, the duration of the SGRT-preparation was manually recorded. Starting when the preparation tool was opened and continuing until the work was saved. Additionally, time measurements were also conducted on the treatment units when necessary. The additional adjustments on the treatment units were carried out by the RTTs who were working on that treatment unit at that time.
