bSSFP imaging enjoys widespread clinical use due to its high time efficiency and fluid-tissue contrast. Previous work with the elliptic signal model (ESM) and geometric solution (GS) inspire further analytical parameter quantification. Here the first exact solution for relaxation parameter T2 mapping is proposed based on the geometric properties of the ESM. Coupled with artifact-free images and field maps, a comprehensive imaging resource is generated. The analytic solution for source ESM parameters is proven to be relatively robust to variations in noise levels, T2 values and band proximity, and hence inspires a novel solution for T2 computation.
