Figure 1. Schematic overview of the spatial resolution measurement of the line-source centered in 20 cm PMMA.
Shown are the camera, including the collimator (A), a stack of 20 PMMA slabs of size 40×40×1 cm (B), the location of the line-source (C), and the patient bed (D). The line-source to collimator-face distance is 11 cm.
