Rationale

Slice count + rotation speed define clinical capability. Tube model, heat capacity, and cooling rate drive cost of ownership — tube replacement is often the largest line item on a CT's service history. Dose reduction technology has regulatory + clinical implications that affect resale value. Cardiac + dual-source capability sets the ceiling on clinical applications.
