Relaxation Measurement of Ex-Vivo Breast Cancer Tissues at Ultralow Magnetic Fields

Figure 1

Schematic diagram of the experimental apparatus for the microtesla NMR experiment. The axes of the 1st and 2nd coils are parallel. However, these are perpendicular to the axis of the coil. The 1st coil is a liquid nitrogen (LN2)-cooled pancake-type coil. The LN2 flowed continuously from the reservoir to the 1st dewar through two tubes at the bottom and then the nitrogen gas flowed back to the reservoir through the upper tube.
