Abstract
A 3D-scanner for direct three-dimensional imaging using a γ-γ-coincidence technique is presented. The characteristics of the system were demonstrated by isoresponse curves and modulation transfer functions. A phantom study showed the possibility of detecting cold nodes when they are invisible in normal scans in large subjects because of masking by overlying activity.
