Imaging skins: stretchable Gd2O2S:Tb X-ray detectors for image-guided surgery.
Article in International journal of computer assisted radiology and surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeWith the growing demands for diverse X-ray imaging applications, there is a need for the development of flexible X-ray detectors to enable conformity to curved surfaces, improving spatial resolution, reducing X-ray exposure, and extending the potential of X-ray imaging to fields such as minimally invasive surgery, which would not be achievable using conventional rigid flat-panel detectors.
methodsIn this paper, we fabricate imaging skins-flexible and stretchable Gd2O2S:Tb-elastomer scintillator films-and integrate them into an indirect X-ray imaging system. We characterise X-ray imaging performance and mechanical properties of the imaging skins, investigating the impact of varying film fabrication parameters such as thickness and concentration.
resultsThe results demonstrate the clinical suitability of the imaging skin system, achieving 1.05 to 2.18 lp/mm at 10% contrast despite the low X-ray energy used, which is comparable to clinical CT. Additionally, the high stretchability (255%) from the elastomer component was maintained in imaging skins with up to 50% Gd2O2S:Tb loading.
conclusionThis work provides a basis for the integration of imaging skins in clinical settings, where they have the potential to be used for real-time intraoperative image guidance. Future work will investigate dynamic and tomographic imaging methods, determine effective deployment strategies of the imaging skins onto organ surfaces, and investigate the effects of imaging skin deformation on image quality.
