Founded last year in Scottsdale, Ariz, Trilogy Imaging Partners aims to bring transparency and efficiency to the used medical equipment market by borrowing the approaches of well-known Web sites like eBay and Yelp. The company consists of an online auction site and a separate resource directory that allows biomeds to rate third-party service providers. Founder and CEO Elizabeth Frazier spoke with 24x7 about Trilogy’s platforms and how they can help biomeds get better service and value.
