Forbild phantom
WebJul 7, 2012 · This note offers tools for computer simulations using a two-dimensional (2D) phantom that models the central axial slice through the FORBILD head phantom. Introduced in 1999, in response to a need for a more robust test, the FORBILD head phantom is now seen by many as the gold standard. WebAug 4, 2014 · Shepp-Logan phantom is tested in this paper as shown in Figure 1, and the size of phantom image is 256 × 256. Without losing generality, we choose a fan beam imaging geometry to capture the projection data as illustrated in Figure 2. The source to rotation center distance is 40 cm and the detector to rotation center is 40 cm.
