doi: 10.1073/pnas.2210214120

Figure Lengend Snippet: Concept and in silico framework. ( A ) Imaging geometry. The main difference between conventional and phase-contrast chest radiography using PBI is the propagation distance z . ( B ) X-ray spectra simulated in this study, with a conventional 120-kVp tungsten spectrum with 4.3-mm Al filtering (dashed) used to simulate conventional radiographs and monochromatic 60 keV (blue) used to simulate phase-contrast radiographs. ( C ) In silico framework for virtual radiography (see details in the Methods section). (Scale bar, 5 cm ( C ).)

Article Snippet: We applied postprocessing to the simulated radiographs with a vendor-specific processing software application for chest radiography (Siemens AG).

Figure Lengend Snippet: Bar chart of relative motion area with representative images of the standard reconstruction and motion-compensated reconstruction. Bar chart presenting the distribution of cases based on the relative difference in motion area between motion compensated reconstruction (MCR) and standard reconstruction (SR), where 0% represents cases with no difference. The bars to the left indicate a decrease in motion area with MCR compared to SR, while the bars to the right show an increase. Representative images indicating the motion area and segmentation results for SR and MCR are indicated at the top of the figure. The resulting motion area in pixels is given in the bottom-right corner

Article Snippet: In our study, we use a vendor-specific motion-compensated reconstruction (MCR) (“Precise Cardiac,” Philips Healthcare) incorporating all the steps as part of the reconstruction pipeline, leveraging data from adjacent cardiac phases within a single cardiac cycle to generate motion-corrected images [ – ].

Figure Lengend Snippet: Standard reconstruction vs. motion compensation reconstruction of the coronary CTA image. Clinical examples of a standard coronary computed tomography angiography image (physiologic cardiac phase 78% RR interval) that ( A ) contains severe motion artifacts in the right coronary artery (non-diagnostic segment, white arrowhead) with standard reconstruction (SR) and ( B ) with motion compensated reconstruction (MCR) that reduced the motion artifact, enabling accurate assessment of this segment (Likert score 3)

Figure Lengend Snippet: Histogram of the total number of non-diagnostic segments at ≥ 70 bpm of coronary CTA with and without motion compensation. Total number of non-diagnostic segments (Likert score of 1) across 50 patients at ≥ 70 beats per minute (bpm) is shown for motion compensated reconstruction (MCR) (gray) and standard reconstruction (SR) (black) at 78% of the cardiac phase. Each bar represents the number of non-diagnostic scores per respective segment. For all segments, the corresponding number of cases is given centrally in each bar
