Low-cost and compact second harmonic laser for photoacoustic imaging.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Photoacoustic imaging (PAI) combines the high contrast of optical imaging with the high resolution of ultrasound imaging, which has garnered significant attention in applications such as vascular imaging and liver function reserve (LFR) assessment. The realization of low-cost and miniaturized light sources is a crucial development direction for the future application and commercialization of PAI. Traditional high-power pulsed lasers (hundreds of millijoules range) are bulky and expensive, although light-emitting diodes (LEDs) are lower in cost and more compact, their output energy is relatively weak (microjoules range), and their pulse width is wide (tens of nanoseconds range), making them unsuitable for high-resolution PAI of clinical application. This paper proposes a low-cost, compact PAI light source based on a miniature laser commonly used in laser communication and laser radar systems, combined with a second-harmonic generation (SHG) crystal. The primary diode pumped solid-state laser (DPSS) has the following specifications: dimensions of 110 × 40 × 24 mm
