Resolution-enhanced transport of intensity phase imaging using contrast transfer function reformulation and SNR-guided deconvolution.
Article in Biomedical optics express, 2026. 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
The transport of intensity equation (TIE) is a powerful phase imaging technique. However, its formulation fails to account for the off-axial transfer function due to the paraxial approximation. To address the resulting image degradation, we analyze TIE phase retrieval using the contrast transfer function (CTF) framework. The attenuation of high-frequency components, leading to the loss of fine structural details, is assessed and restored through Wiener deconvolution. Simulations and experiment results demonstrate significant enhancements in sharpness, contrast, and structural clarity. We showcase enhanced phase imaging of cheek cells, revealing finer subcellular details and achieving diffraction-limited performance, contributing to advances in super-resolution phase imaging.
