Quantifying gantry rotation speed and gating effects on CBCT isocenter accuracy for radiotherapy image acquisition.

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
The Varian TrueBeam v4.1 enables a faster gantry rotation speed (9 deg/s) than previous versions (6 deg/s). In this longitudinal study, we assessed the impact of gantry rotation speed, fan geometry, and gating on imaging isocenter stability over 1 year. A ball bearing (BB) was CBCT imaged and raw projections were analyzed to extract BB displacement at each projection angle. The average BB displacement was 0.04 ± 0.03 mm. The maximum displacement of the BB was 0.15 mm, which is within 1.00 mm isocenter tolerances. Increased gantry rotation speed does not have a clinically meaningful impact on imaging isocenter stability.
