Autonomy for MRI Field Cameras: Synchronization, Self-Calibration, and Sequence Detection.
Article in Magnetic resonance in medicine, 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
purposeThis work aims to provide a workflow for operating NMR field probes in MR scanners independently of pulse programming, scanner TTL trigger pulses and dedicated calibration sequences.
methodsAn independent timing system and limited prior knowledge about relative probe positions enable synchronous field measurement, probe position calibration, and sequence parsing.
resultsThe proposed procedures were implemented and tested by measurement in a 3 T MRI system. They were found to achieve field-probe and field-camera functionality fully independently, without connection to or communication with the scanner. Autonomous position calibration deviated from the conventional method by less than 300 μm. Self-synchronization permitted the recording of sequence schematics and targeted measurement of sequence features of interest.
conclusionMagnetic field sensing in MRI systems can be rendered autonomous and self-reliant for independent measurement. This capability paves the way for platform-agnostic field cameras and could readily integrate with existing systems.
