Transaxial slice of an image quality phantom, scanned on a Siemens mCT, reconstructed using different methods. (a) A standard iterative algorithm (OSEM) at typical pixel size of 4 mm, (b) OSEM + PSF with 2-mm pixel size, (c) OSEM + PSF + TOF with 2-mm pixel size, (d) OSEM with 2-mm pixel size, and (e) OSEM + TOF with 2-mm pixel size.
