About the Evidence Document

The “Evidence Document” provides a comparison of the imaging technologies using the DEXIS Platinum Sensor with DEXIS Imaging Software (“DEXIS”) and the Schick 33 Sensor with Patterson Imaging Software (“Schick 33”) in internally conducted laboratory bench studies*. The performance bench data was generated by using the listed devices within the boundaries of the cleared indications for use. The data was obtained using standard methodologies (phantoms, controlled conditions, etc.) that are accepted in the industry as representative of real world experience that is obtained in larger, heterogeneous and more complex populations, with a broader range of end-users. These types of studies and the presented data are useful for identifying less evident but common technological benefits and limitations. The presented data can be recreated using the presented technologies under the same conditions for repeatability purposes.
