N2 - PET scanners are designed to function over a wide dynamic range of imaging conditions. Clinical constraints, such as injected activity and imaging time, often limit the realization of optimal system capability. The 'working range' of image quality for a given imaging situation is dictated by a trade-off of signal to noise. By adjusting scan time and reconstruction parameters, an acceptable trade-off is fixed into a protocol. This study develops the use of quantitative measures using hot and cold rods inserts in head and body-sized phantoms to quantitatively and visually assess two different PET scanner geometries and multiple reconstruction methods in order to further understand optimal scanner design and use in different imaging conditions.
