Evaluation of reconstruction quality based on screw FWHM, screw thread frequency peak height and SSIM for circular and task-aware trajectories and different noise levels on simulated data.

screw FWHM [mm] thread frequency height SSIM to ground truth
ground truth 3.92 6.83 1.00
circular no noise 6.38 9.05 0.83
circular 4 ⋅ 105 photons/pixel 6.35 8.96 0.81
circular 5 ⋅ 104 photons/pixel 6.19 7.52 0.69
task-aware no noise 3.65 7.57 0.90
task-aware 4 ⋅ 105 3.72 8.31 0.89
task-aware 5 ⋅ 104 4.10 6.95 0.85
