Spatially compounded plane wave imaging using a laser-induced ultrasound source.
Article in Photoacoustics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
This work presents spatially compounded plane wave imaging using a laser-induced ultrasound source. The plane wave source consisted of a 30 μm thick film of carbon black-doped PDMS cured on a 100 μm thick polyester substrate and presented a rectangular aperture of 40 × 3 mm. It was placed in front of a linear ultrasound array, passing through the imaging plane allowing overlap of the detection plane and the insonification plane. Illumination was provided by an array of optical fibre bundles placed above the imaging plane, at an angle. We will first present the general imaging set up and instrumentation used, after which details are given on the fabrication of the transmitter itself and on the objects that were imaged. Comparing laser-induced and conventional ultrasound images of wire phantoms shows the point-spread-function to be, in general, slightly better laterally in the conventional case but more homogeneous throughout the imaging plane with the laser-induced source. Imaging of a tissue-mimicking phantom shows a 55% improvement in contrast between a tumour and the background when using laser-induced ultrasound, as compared to the conventional case.
