Comparison of catheter tracking with (a) PR and (b) Cartesian acquisitions, showing a single frame from real-time imaging in the same pig with each trajectory, at the same slice orientation. Imaging parameters for PR were: FOV = 32 cm, slice thickness = 8 mm, 160 Nr × 48 Np, receiver bandwidth = ±62.5 kHz, TR/θ = 4.1 ms/50°, resulting in 2 × 2 × 8 mm spatial resolution and 5.1 fps. For Cartesian: FOV = 36 cm, slice thickness = 8 mm, 192 Nx × 96 Ny, FOV = ¾ (72 views), receiver bandwidth = ±125 kHz, TR/θ = 3.7 ms/60°, resulting in 1.8 × 3.7 × 8 mm spatial resolution and 3.8 fps. SSFP was employed for both acquisitions.
