Aberration correction and complementary beam subtraction in light-sheet fluorescence microscopy.
Article in Journal of biomedical optics, 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
Significance: Scanning nondiffracting Bessel beams in light-sheet fluorescence microscopy (LSFM) can expand the field of view (FOV), but side lobes of the Bessel beams produce the out-of-focus background and limit the axial resolution. Furthermore, optical aberrations degrade the image quality and affect the imaging depth. Aim: To compensate wavefront distortions and enhance the imaging performance in LSFM, we propose a method that combines the adaptive optics (AO) with the complementary beam subtraction (CBS) method in LSFM, referred as AO-CBS. Approach: In the AO-CBS method, the sensorless AO is employed to correct optical aberrations in LSFM, resulting in a notable enhancement of image contrast and signal intensity by 48%. Higher axial resolution is achieved by effectively removing the out-of-focus background through subtracting the two image stacks acquired by scanning the Bessel beam and its corresponding complementary beam. Results: The final axial resolution is improved from Conclusions: The AO-CBS method effectively addresses key issues existing in traditional Bessel beam-based LSFM, including the sidelobe-induced out-of-focus background, the limited axial resolution, and the degraded image quality caused by optical aberrations. The successful application of this idea in LSFM can serve as a design strategy to enhance the light-sheet-based imaging systems, thereby promoting the development and the application of LSFM and providing more powerful tools for biomedical imaging.
