The FWHM measurement shown by the profile curve on the spinous process cross-section. a Spatial resolution of three reconstructions at various iterations. The dotted line is the actual size of the phantom. Unfilled triangle indicates Flash 3D (F3D). Unfilled circle indicates xSPECT Quant (xQ). Unfilled square indicates xSPECT bone (xB). b A sample measurement of an xB image at 12 iteration numbers. c A measurement profile of an xB image at 12 iteration numbers. The plateau signal around the spinous process is a distribution of background region in the phantom
