In PET system development, detector performance is often discussed in terms of crystal material selection (LYSO, LSO, BGO). However, material choice alone does not determine final system performance.
In practice, PET image quality, TOF resolution, and long-term stability are equally shaped by how scintillation crystals are manufactured, processed, and assembled into detector blocks.
This article walks through the critical manufacturing stages — from crystal boule growth to finished detector arrays — and explains which factors truly matter at the system level.
