Low-Dose and Scatter-Free Cone-Beam CT Imaging Using a Stationary Beam Blocker in a Single Scan: Phantom Studies
Figure 2
1D horizontal profiles of the scatter, projection, and line integral signals acquired from the Catphan 600 phantom: (a) estimated and reference scatter, original projection signals; (b) line integrals of CBCT projections with and without the proposed correction and with a fan-beam geometry. Different markers are plotted to demonstrate the data acquired from direct measurement (circle) and primary compensation (triangle).
