On the other hand, we see emerging interest in cardiology for using this clinical utility as well. That represents an emerging opportunity, from both a clinical and a business point of view. We would like to work with physicians both in radiology and cardiology to provide the right tools for their clinical applications. But there's nothing to prevent aggressive entrepreneurial cardiologists who believe in the technology to ramp it up fast, because they control the patient. Vascular surgeons control the patient.
Radiologists rely on referrals.
It depends on who takes a leadership role. It's a difficult line for industry to walk right now, because of our commitment to the radiology community.
