Operational Improvement of a Proton Therapy System From Reduced Energy Layer Switching Time.
Article in International journal of particle therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: This study reports the potential operational improvement provided by reduced energy layer switching time and total beam delivery time of a 3-room IBA ProteusPLUS system. Materials and methods: Eight treatment fields, including various disease sites and a reference cube, were analyzed for energy layer switching time and total delivery time before and after an energy layer switching time upgrade. The upgraded beam delivery time estimated the total treatment capacity for a 12-h treatment day using a 3-room system with a single common cyclotron. The potential increase in revenue was estimated using Medicare reimbursement rates for proton therapy intermediate. Results: The average layer switching time was reduced from 6.33 to 1.86 s, reducing the average field delivery time from 240 to 113 s. Overall, the average energy layer switching time reduction was 70.6%, and the average total treatment field delivery time was reduced by 52.6%. Head and neck cancer fields experienced the greatest treatment time reduction of 59.5%, reducing from 236 to 95.5 s. The treatment field delivery time reduction allowed an increase from 60 to 127 patients per day, an increase of 112%. Conclusion: Reductions in energy layer switching time significantly decreased treatment field delivery time. Reduced treatment field delivery time may provide clinical benefits to patients through improved patient alignment and comfort. Increased treatment capacity could also improve patient access to proton therapy for disease sites that may experience clinical benefits, such as head and neck cancer.
