Adaptive dual-speed ultrasound and photoacoustic computed tomography.
Article in Photoacoustics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Full-ring dual-modal ultrasound and photoacoustic computed tomography has unique advantages of nearly isotropic spatial resolution, complementary contrast, deep penetration, and full-view detection. However, the imaging quality may be deteriorated by the inaccurate sound speed estimation. Automatic determining and compensation for sound speed has been a long-standing problem in image reconstruction. Here, we present new adaptive dual-speed ultrasound and photoacoustic computed tomography (ADS-USPACT) to address this challenge. The system features full-view coverage (360°), high-speed dual-modal imaging (10-Hz), automated dual sound speed correction, and synergistic high imaging quality. To correct the sound speed, we develop a two-compartment method that can automatically segment the sample boundary and search for the optimal sound speed based on the rich ultrasonic pulse-echo signals. The method does not require the operator's intervention. We validate this technique in numerical simulation, phantom study, and in vivo experiments. The ADS-USPACT represents significant progress in dual-modal imaging.
