TIM

Siemens' coil platform — multi-element matrix coils that can combine up to 76 elements. Introduced ~2003 on Symphony.

Why it matters to buyers: TIM-compatible coils are cross-compatible with newer Siemens systems (Avanto, Aera). Major resale value driver on refurb Symphony.

Why it matters to engineers: Variants use channel×element counts (8×18, 18×46, 32×76). Higher tiers support more parallel-imaging acceleration.
