In this work,
dynamic 3He and 1H images were acquired in a synchronised scan during
inhalation providing regional gas flow with spatially and temporally
registered lung anatomy motion. Lung ventilation is very fast (air reaches
lung periphery within 1s) and demands fast sequences that can capture the
rapid flow of 3He gas in lung airways. Compressed Sensing (CS) was used to
assess the feasibility of accelerated synchronous 3He/1H acquisition.
