Subject grounding to reduce electromagnetic interference for MRI scanners operating in unshielded environments

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Portable low‐field (<0.1T) MRI is increasingly used for point‐of‐care imaging, but electromagnetic interference (EMI) presents a significant challenge, especially in unshielded environments. EMI can degrade image quality and compromise diagnostic utility.

Design and performance of a toroidal radiofrequency volume coil with intrinsic electromagnetic interference rejection for low‐field portable Halbach‐based MRI systems

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose One of the intrinsic limitations of low‐field MRI is low signal‐to‐noise ratio, which can be further reduced by electromagnetic interference (EMI) due to the lack of a Faraday shielded room. To address this issue, we propose a novel radiofrequency (RF) coil design that is inherently less sensitive to EMI while maintaining high receive ...

Experimental Modal Analysis‐Driven Gaussian Process Regression Modeling of Rectangular Steel Beams With Various Hole Geometries

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Pollination biology and reproductive ecology of critically endangered endemic Campanula teucrioides in western Anatolia

open access: yesNordic Journal of Botany, EarlyView.
Campanula teucrioides Boiss. is a critically endangered species found in a single locality in western Turkey. Determining the population size of C. teucrioides and conducting reproductive biology studies are of great importance in determining the necessary strategy for the conservation of the species. The area where the plant distributed was determined
