Low cost full field optical coherence tomography device using a DVD optical head and smartphone camera.
Article in Scientific reports, 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
In this article, we introduce a low cost full-field optical coherence tomography (FF-OCT) system that combines DVD optical lenses with smartphones technology to create a portable imaging device. The DVD lenses, extracted from optical pickup units(OPU), are mounted on a voice coil actuator, which enables high-speed and precise displacement. They also feature a built-in stabilization mechanism and a control circuit that minimizes external disturbances such as vibrational noise, ensuring consistent imaging performance. By integrating these compact lenses, we developed a lightweight and cost-effective FF-OCT device with automatic alignment capabilities, making it ideal for point-of-care diagnostics. The main structure of the device is 3D-printed, while a smartphone handles data acquisition, processing, and display, further enhancing affordability and accessibility. To assess imaging performance, we evaluated lateral resolution using a CD disk grating with a 1.6 [Formula: see text] periodicity. The lateral resolution of the system was estimated to be approximately 0.94 [Formula: see text]. Additionally, we captured en-face images of tissue and onion layers as a proof of concept, demonstrating the device's potential for biological imaging.
