Data Spectrum Phantom was imaged with a set high resolution collimators, 2 minutes per slice, and a 4 mm patient couch step. The data was then reconstructed with the new fully three-dimensional maximum aposteriori (MAP) reconstruction. 20 slices of the 40 aquired, are displayed with a slice thickness of 4mm. There are about 3 million counts in the rod section of the phantom and 8 million counts in the spheres section. The rod diameter are as follows 4.8mm, 6.4mm, 7.9mm 9.5mm 11.1mm and 12.7. The sphere diameters are as follows 9.5mm, 12.7mm 15.9mm, 19.1mm and 25.4mm, 31.8mm. This clearly illustrates the super high-resolution of the NeuroFOCUS camera.
