Magnetic Resonance Imaging (MRI) is a highly sensitive diagnostic tool that is greatly affected by the physical conditions of its installation environment. Mechanical vibrations and magnetic field interferences are critical factors that can compromise image quality. In Mexico, there is currently no Official Mexican Standard regulating the installation conditions for MRI equipment, which leads to a concerning variability in the technical criteria used. This study aimed to characterize, in a controlled environment, the physical disturbances—structural vibrations and AC/DC magnetic interferences—at a simulated MRI installation site. High-precision sensors calibrated by the National Metrology Center (CENAM) were used, and an experimental protocol was designed based on international recommendations (such as AAPM Report No. 20) and parameters from commercial manufacturers.

The application offers an intuitive interface with time- or frequency-based analysis, comparison with reference models, and graph generation to support technical decision-making. The results highlight the need to establish a solid regulatory framework in Mexico to ensure proper MRI system installations and thus guarantee their optimal clinical performance.

摘要

Magnetic Resonance Imaging (MRI) is a highly sensitive diagnostic tool that is greatly affected by the physical conditions of its installation environment. Mechanical vibrations and magnetic field interferences are critical factors that can compromise image quality. In Mexico, there is currently no Official Mexican Standard regulating the installation conditions for MRI equipment, which leads to a concerning variability in the technical criteria used. This study aimed to characterize, in a controlled environment, the physical disturbances—structural vibrations and AC/DC magnetic interferences—at a simulated MRI installation site. High-precision sensors calibrated by the National Metrology Center (CENAM) were used, and an experimental protocol was designed based on international recommendations (such as AAPM Report No. 20) and parameters from commercial manufacturers. A digital tool was also developed using MATLAB App Designer to visualize and analyze the collected data, allowing for the evaluation of the electromagnetic and structural compatibility of the simulated site. The application offers an intuitive interface with time- or frequency-based analysis, comparison with reference models, and graph generation to support technical decision-making. The results highlight the need to establish a solid regulatory framework in Mexico to ensure proper MRI system installations and thus guarantee their optimal clinical performance.
