ESTRO38 Congress Report

Figure 1: Time-resolved doses to a point. (top) dose rate and (bottom) cumulative dose during the first 50s of a fraction in a point in the cranial part of the tumor (indicated by the white dot in Figure 2) as calculated in real-time during treatment by DoseTracker (left) and post-treatment by the treatment planning system (TPS) (right). Actual (red, thin line) and planned (black, thick line).

Figure 2: Dose distribution. Top: Planned and actual dose distributions in the coronal slice through the isocenter for DoseTracker (left) and the treatment planning system (TPS) (right) after delivery of the whole fraction. The dose color wash range is 95- 107% of the mean CTV dose as calculated by DoseTracker and the TPS, respectively. The PTV was prescribed 67% dose. The time-resolved dose in the point indicated by a white dot is presented in Figure 1. Bottom: Dose volume histograms for the CTV as planned (black) and actually delivered (red) for the DoseTracker (left) and TPS (right) doses. The motion-induced reduction in CTV D_95 is indicated.
