1 · What the graph read from it

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.

2 · The registry

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

Tomography enables volumetric visualization of internal structures with high fidelity, which has transformed diverse fields of science and engineering. Ultrasound tomography, in particular, provides radiation-free, real-time, and low-cost imaging. Conventional linear and planar array designs typically impose inherent limits on aperture, coverage, and resolution, hindering accurate imaging of deep structures. Here, we present an active and programmable circular meta-array of 2048 channels integrated with cylindrical acoustic lenses, generating a wide-angle point-source radiation in plane and a thin flat sound-sheet beam out of plane. This configuration delivers omnidirectional homogeneous coverage and dynamic focusing, allowing comprehensive full-matrix echo acquisition. Based on the circular meta-array, subwavelength resolution ultrasonic images (∼0.8λ) are obtained with delay multiply and sum reconstruction. Extending to the volumetric tomography, the acoustic system reconstructs complex 3D objects and resolves human soft tissues and musculoskeletal structures. Our work provides a versatile platform for ultrasound tomography and opens an avenue for various advanced applications in biomedical imaging and therapeutic monitoring.
