Image /page/16/Picture/1 description: The image contains the logo for United Imaging. The logo consists of the words "UNITED IMAGING" in bold, sans-serif font, stacked on top of each other. To the right of the text is a stylized "U" shape, which is dark gray and has a white horizontal line through the middle. The logo is simple and modern in design.
#### 9. Performance Data
The following performance data were provided in support of the substantial equivalence determination.
## Biocompatibility
Not Applicable to the proposed device, because the device is stand-alone software.
## Electrical Safety and Electromagnetic Compatibility (EMC)
Not Applicable to the proposed device, because the device is stand-alone software.
