Abstract :
The authors present a novel SPECT imaging technique for small animal research based on multipinhole collimation. This new method is an extension of single-pinhole tomography and combines high resolution with increased system sensitivity. This paper describes the multipinhole imaging system and its preliminary characterization on simulated and measured phantom data.
