Meaning
Automated three-dimensional measurements of the electric field within tissue-equivalent models determine the total absorbed RF energy. A SAR volumetric scan is performed to map the distribution of electromagnetic energy inside the simulated tissue.
Probe Trajectory
High-precision robotic arms move E-field sensors through a series of grid points in the liquid. During a SAR volumetric scan, the robot moves the probe in a grid pattern to capture the field strength. The system records the coordinates and the corresponding field intensity at each measurement point.
Data Interpolation
Computational algorithms use the measured grid points to reconstruct the continuous field distribution inside the phantom. The resulting data from a SAR volumetric scan allows the system to identify the locations of peak energy deposition. These peak values are then averaged over a specific mass of tissue.
Certification Report
Regulatory submissions must include the results of the spatial averages calculated from the measured grid. The data from the SAR volumetric scan provides the documented proof needed to demonstrate compliance with international safety guidelines. Because the scan covers a large volume, it ensures that all potential hotspots are captured and analyzed.
This comprehensive coverage prevents the omission of any localized exposure peaks, which is essential for ensuring that the final consumer product is completely safe for use.
