The comparison of scatter signal profiles estimated from SVSC (solid green lines) and MVSC (solid red lines) when the blocker edge detection error occurs for the anthropomorphic pelvis phantom (3.2 mm pitch blocker).

<p>The red dashed line and green dashed line are the derived adaptive threshold and the fixed threshold (mean of the profile) for blocker detection, respectively. The observed total signal is in black.</p

Comparison of the horizontal line profile (red line in Fig 14) for Elekta with U-SC, Varian with K-SC and MVSC.

<p>The MDCT profile serves as the ground truth.</p

Robust moving-blocker scatter correction for cone-beam computed tomography using multiple-view information - Fig 7

<p>Projection images of the Catphan phantom (the line integral of attenuation coefficients by taking logarithm of inversely normalized X-ray fluence): a) without blocker; b) with SVSC; and c) with MVSC. Each image was normalized to its maximum intensity value, respectively.</p

The comparison of scatter signal estimated from the single-view scatter correction (SVSC) method (green line) and the multi-view scatter correction (MVSC) method (red line) for the Catphan phantom (3.2 mm pitch blocker).

<p>The observed total raw signal is in black.</p

The moving blocker CBCT system.

<p>The rotational axis of the gantry is z and the blocker is moving back-and-forth in z direction. The blocked region detects the scatter signal and the unblocked region detects the total signal, i.e. the sum of the primary and scatter signals.</p

The comparison of the scatter signal profiles estimated from SVSC (green line) and MVSC (red line) when the left marginal region is lack of scatter samples for the anthropomorphic pelvis phantom (9.6 mm pitch blocker).

<p>The observed total signal is in black.</p

Schema of effects on respiration.

<p>CDCA, DCA, LCA, CA and FXR agonist GW4064 influence respiration via FXR represent by changes in respiratory cycle, inspiratory time, expiratory time and integral amplitude. To confirm the involvement of FXR, the FXR inhibitor Z-guggulsterone is co-administered with the above bile acids and GW4064, completely reversing their effects on respiration.</p

Blocker edge detection for a small object (left) and a large object (right).

<p>The green arrows denote the position for reliable edge point detection in high-contrast regions. The edge is estimated as the line connecting two edge points. The red solid lines represent the true blocker edges and the red dashed lines are the estimated edges.</p
