Validation of Treatment Planning Systems based on Dose Calculation Accuracy for Extended SSD Total Body Irradiation with and without Beam Spoiler.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aims: This study aimed to confirm the accuracy of the dose calculation by commercially available treatment planning system (TPS) at the extended SSD = 350 cm with and without beam spoiler configurations. Materials and Methods: Two extended SSD plans, one without a beam spoiler and another with a beam spoiler, were created on a virtual phantom in Eclipse TPSs for 6 MV photon beam. Using dosimetry tools, percentage depth doses (PDDs) and in-line profiles of both plans were generated. Beam properties of the TPS calculated PDDs and profiles were compared with manually calculated and measured PDDs and profiles. Reference depth dose was calculated in two different phantoms and measured using an ion chamber and TLDs. Results: At the extended SSD setup, the TPS calculated and measured PDD with and without beam spoiler were in agreement within 2%. This agreement was observed at the surface and in the buildup region as well. Flatness and symmetry of the profiles with and without beam spoiler were within ± 3%. The TPS calculated dose at a reference depth in a homogeneous and a heterogeneous phantom was agreed with measured dose using an ion-chamber and TLDs. Conclusion: This study validated the TPS for extended SSD total body irradiation (TBI) dose calculation with and without beam spoiler. Developing computed tomography based field in field plan for homogeneous dose distribution may be feasible. This technique may allow us to treat extended SSD TBI in less time while maintaining dose calculation accuracy.
