Monte Carlo-Based Optimization of Multi-Source Illumination for Photoacoustic Signal Generation in Human Gray-Matter Vessels.
Article in Journal of biophotonics, 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
Effective excitation of cerebrovascular photoacoustic signals is limited by superficial tissue attenuation and illumination geometry. This paper proposes a multi-source illumination evaluation method for gray-matter vessel targets based on Monte Carlo light transport and photoacoustic initial-pressure calculation using a simplified multilayer brain model for screening and a Tissue Probability Map (TPM) brain model for validation. The dual Collimated Gaussian source with 15° symmetric incidence along the Y direction performed best in the regular layered model, whereas the dual Pencil Array source with 20° symmetric incidence along the Y direction was optimal in the TPM model. These results suggest that regular layered models are suitable for preliminary screening, but the final illumination scheme should be revalidated under anatomical constraints. This study provides a theoretical reference for optimizing optical-source configurations in human brain photoacoustic imaging.
