Buying a used GE ultrasound: a checklist

What to verify before buying a refurbished GE LOGIQ, Vivid or Voluson ultrasound system.

Confirm the exact BT (Breakthrough) version and software revision.
Check which transducers are included and their condition — probes are a major cost.
Verify the system powers up, boots and passes self-tests.
Ask for the DICOM / connectivity options and any licensed features.
Confirm cosmetic condition, monitor type and cart.
