Handheld Analyzer Enhances MRI Service Efficiency

This case study details the implementation of the Keysight N9918A FieldFox handheld RF and microwave analyzer by a Japanese medical equipment company to improve the servicing of MRI machines. The previous method involved cumbersome setups with benchtop equipment, which complicated the tuning of MRI RF coils and required technicians to work at a distance from the MRI machine due to magnetic field interference. The FieldFox provided a portable solution that allowed for quicker and more efficient maintenance cycles. Technicians reported a 50% reduction in service time and a 30% increase in the detection of RF shielding problems. The analyzer's capabilities include interference monitoring and wireless signal coverage assessments, which are critical in hospital environments. The FieldFox supports site surveys to check for stray RF waves that could affect MRI functionality, allowing for immediate responses to potential RF shielding effectiveness changes. Overall, the FieldFox has facilitated faster diagnostics and increased operational efficiency in MRI servicing.
