background

● Early detection of a carcinomatous lesion 
● Inaccuracy of depth of interaction (DOI) of gamma rays within the scintillator
● Non-uniformity of PET image at the edge of vision  
● Low-cost and compact PET detector is strongly awaited

summary

● Resolution improvement  for the PET scaner
● 3D measurement of  incident gamma rays  
● Novel optical sensor of the magnetic field resistant

predominance

● Novel simple DOI method using MPPCs
● Achieving submillimeter resolution in 3D measurements of incident gamma rays 
● Very easy to fabricate,  resolution better than e.g., X’tal Cube

application/development

● High Resolution PET scanner
● Next generation PET, MRI/PET, TOF/PET
● Small environmental gamma camera
