1. Fig. 1. Pulse sequence diagram of balanced steady-state free precession. Sum of all gradients in each of three directions (slice-selection, phase-encoding, and frequency-encoding) is zero. Phase of radio frequency (RF) pulse, denoted as phase-cycling angle (θ), can be incremented after every repetition time (TR). Echo time (TE) is typically set to half of TR. GSS, GPE, and GFE represent gradients for slice selection, phase encoding, and frequency encoding, respectively.
