52 Do Robotics Help here? Credentials/ Training Radiation Exposure Marketing Variable Expertise Contrast Doses Consistency In Outcomes

53 Conclusions What we think we know Radiation exposure is less to us and patients (?) Advancements in technology has allowed for integration to many procedures Certain procedures with challenging anatomy may be best suited for robotics What we don t know Is this incremental cost worth it? Who s going to pay for it? Will this result in incremental improved outcomes Will the future pipeline further improve outcomes and safety
