A method and apparatus for acquiring total uniformity for a scintillation imaging apparatus are provided. A generic energy (Z) map is first obtained. The generic Zmap is then corrected for linearity by use of a dot pattern. The listmode data is used to construct an energy histogram matrix. A twin Zmap is then obtained by optimizing the lower and upper boundaries of the energy window for each pixel in relation to the average energy over the Center Field of View.

Non-uniformity energy correction method and apparatus

In some preferred embodiments, a medical imaging system having stable camera optics is provided that includes: a photon emitting source that emits photons towards a plurality of photon receivers; an optical interface between said photon emitting source and said plurality of photon receivers including an optical coupling gel that is prone to discoloration from local contaminants and an optical coating adjacent said optical coupling gel; and said optical coating having means for avoiding discoloration of said optical coupling gel.
