Sensitivity in Head Tissue Frequency: 835 MHz Epsilon: 41.5 (+/-5%) Sigma: 0.90 S/m (+/-5%) ConvF Channel X: 6.6 Channel Y: 6.6 Channel Z: 6.6 Tissue sensitivity values were calculated using the load impedance of the APREL Laboratories Daq-Paq. Boundary Effect: Uncertainty resulting from the boundary effect is less than 2% for the distance between the tip of the probe and the tissue boundary, when less than 2.44mm. Spatial Resolution: The measured probe tip diameter is 5 mm (+/- 0.01 mm) and therefore meets the requirements of SSI/DRB-TP-D01-032 for spatial resolution.
