Description
The design and image reconstruction aspects of a new generation of dynamic SPECT instrumentation utilizing multiple rings of position sensitive photomultiplier tubes (PSPMTs) are reported. A diverging cone-beam collimator is attached to each PSPMT to achieve a 22 cm diameter spherical field of view in a system designed for head imaging. The resolution with the diverging collimator is estimated to be approximately 20% worse than a parallel hole collimator. Iterative and direct cone-beam reconstruction algorithms have been investigated under different conditions of angular sampling and counting statistics. The ramifications of temporal resolution and signal to noise ratio are discussed in relation to dynamic SPECT imaging of labeled cisplatin for chemotherapy
