Generation of a computer-simulated nodule. a The 2D PSF in the xy scan plane obtained for an image reconstruction kernel of FC50. b The SSP obtained for a slice thickness of 1 mm. c Images of the object function in the scan plane (left) and in the xz plane (right), which was generated as an ideal sphere with a diameter of 5 mm. d Images of a computer-simulated nodule in the scan plane (left) and in the xz plane (right), which was obtained from the object function using 2D PSF and SSP
A brief description of one example is given in Fig. 1.
The simulated nodule image (Fig. 1d) was computed from the
object function (Fig. 1c) using 2D PSF (Fig. 1a) and SSP
The 2D PSF was obtained for a reconstruction kernel of FC50
(Fig. 1a), and the SSP was obtained for a slice thickness of
1 mm (Fig. 1b)..
