Elements of cardiac phantom used in this study. (A) Torso-anthropomorphic phantom with dynamic insert simulating beating left ventricle. (B) External pump-control unit.
- FIGURE 2.
End-diastolic (ED) and end-systolic (ES) representative tomographic slices reoriented along major cardiac axes (short axis [SA], vertical long axis [VLA], and horizontal long axis [HLA]) obtained from reconstruction of G-SPECT phantom study with 3D OSEM iterative protocol.
- FIGURE 3.
Measured contrast and noise for various EM-equivalent iterations (I × S product) with fixed gaussian postprocessing filter FWHM value of 10 mm.
- FIGURE 4.
Measured EDV, ESV, SV, and corresponding LVEF with various EM-equivalent iterations (I × S product) and fixed gaussian postprocessing filter FWHM value of 10 mm. Dotted lines represent actual values for EDV, ESV, SV, and LVEF of cardiac phantom.
- FIGURE 5.
Measured LV volumes (EDV and ESV) with different gaussian postprocessing filter FWHM values for various EM-equivalent iterations (I × S product). Dotted lines represent actual values for EDV and ESV of cardiac phantom.
- FIGURE 6.
Calculated LVEF with different gaussian postprocessing filter FWHM values for various EM-equivalent iterations (I × S product). Dotted line represents actual value for LVEF of cardiac phantom.
