Abstract:
An echo-based single point imaging (ESPI) system (10) providing high-resolution oxygen images of a sample is disclosed. The ESPI system (10) employs spin echo detection of the resonance from a spin probe and concurrent Single Point Imaging (SPI) for spatial encoding of the oxygen concentration within the sample. Images are derived by comparing spin echo intensities of two images reconstructed at two time points selected at identical time intervals on either side of a refocusing pulse, eliminating artifacts associated with sample magnetic susceptibility and field inhomogeneity effects.
