Characterization of lesion detection as a function of reconstruction method. (a) Displacement of lesion center-of-mass in (left) superior-inferior (center) anterior-posterior and (right) left–right direction. (b) Shape metrics as a function of respiratory phase: (left) circularity, (center) solidity, and (right) volume of lesion. (c) Sagittal view at respiratory phase 3 for reconstructions with (left) NVS-PEVS, (center) ESP-PEVS, and (right) RSGR-PEVS. Notice truncation artifact and intensity ripples (arrows) caused by the sharp discontinuity in k-space sampling with ESP-PEVS. The effect of view-sharing is shown for the stack-of-stars trajectory. See Supplementary Figure S6 for the multidimensional golden means trajectory.
