Characterization of silicon carbide diodes as cost-effective active detectors for proton UHDR dosimetry.
Article in Medical physics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundProton therapy allows for better localization of the dose distribution in the tumor. In addition, the FLASH effect can be exploited to reduce the toxicity to healthy tissue by using short-pulsed treatment at ultra-high dose rates (UHDR). Such intense radiation conditions have limited options for active detectors for dosimetry. PURPOSE: Silicon carbide-based diodes are proposed as a cost-effective alternative to diamond detectors for dosimetry in UHDR.
methodsTwo new SiC diodes designed and fabricated at the Institute of Microelectronics of Barcelona (IMB-CNM) were exposed to 20
resultsFirst, the single diode showed a good dose rate linearity. No indication of saturation was observed even at the highest dose per pulse (DPP) of 25 Gy. This was observed even after over-exposure of 52 kGy of 7 MeV protons, although its response lowered to 31% of the initially measured value. Second, the beam profiles observed by the pixelated detector were consistent with those of the reference measurements. Finally, the full width half maximums of the pulses observed by the pixels show good correlation with the pulse width of the beam.
conclusionsThe SiC detectors developed at IMB-CNM were able to withstand and accurately measure the dose under FLASH compatible beam characteristics, even in the case of low-energy protons (7 MeV). The pixelated device showed promising results for a full array monitor for quality assurance, and the capability of time-resolved pulse measurements, the latter after optimization of the electronics.
