EMI & vibration survey
EMI (Electromagnetic Interference) Test
Imaging diagnostic equipment such as MRI & CT Scanners are sensitive and can be disturbed by environmental electromagnetic interferences.
An EMI Test evaluates the level and source of electromagnetic interference generated by a number of sources including moving vehicles, trains, elevators, power lines, transformers which may affect the performance of the imaging diagnostic equipment.
The test involves placing a magnetometer at the exact position of the isocentre of the proposed MRI/CT Scanner and measuring over a period of time the AC fluctuations and DC disturbances in X, Y & Z axis.
Information is recorded by the data acquisition unit and will indicate whether the proposed siting of the scanner is within the specification of the MRI/CT Scanner manufacturer.
Vibration Survey
Imaging diagnostic equipment is very sensitive to environmental vibration. Structural vibrations can be generated by a number of sources including motors, pumps, elevators and moving vehicles.
The survey is performed to measure steady state and transient vibration using a PCB Piezotronics Seismic Accelerometer positioned either at the proposed isocentre of the imaging diagnostic unit or a position dictated by the customer. The data acquired and recorded on the data acquisition unit over a period of time will indicate whether the proposed position of the imaging diagnostic unit is within the specification of the MRI/CT Scanner manufacturer.
