Maximally Spaced Projection Sequencing for Uniform Acquisition of Electron Paramagnetic Resonance Imaging Projections

Uniform projection acquisition in electron paramagnetic resonance oxygen imaging reduces artifacts from changes during imaging, enables useful real-time reconstruction, and allows post-factum temporal resolution adjustment. A novel uniform acquisition method is presented as an alternative to the commonly used golden ratio (GR) method. The GR method allows acquisition of arbitrary numbers of projections, maintaining approximate uniformity throughout and for subsets of arbitrary size. In some cases, arrival at a pre-defined final projection set is necessary, which is impossible using the GR method. The maximally spaced projection sequencing method presented enables acquisition of arbitrary projection sets, maintaining approximate uniformity throughout acquisition.
