EPR image of nitroxide-impregnated agarose phantom. End view of an agarose cylinder containing 100 μM nitroxide 2. The cylinder is 6 mm in diameter and 3 mm in length. Cross-sectional view shown is from the approximate center of the cylinder's axial dimension. The known geometry of the cylinder is well represented in the image. Signal from the cylinder is imaged with a signal-to-noise ratio of 79 and a spatial resolution of 4.4 mm. All axis labels are in centimeters and spectral intensity is encoded according to the scale shown on the right
