The gamma probe at the OR table —per-indication probe choice and joint workflow.

One console, two scintillator families, more than 28 probe models. The decisions that matter on the OR list are the per-indication probe choice (which scintillator, which geometry, collimated or open), the joint nuclear-medicine + OR workflow on the morning of surgery, and the OR-side ergonomics that decide whether the platform actually gets used after the procurement budget is signed.
