Turning VH IVUS Display On/Off

available for the Eagle Eye catheter family. When the VH button is selected, it allows
VH IVUS to be shown. The default mode for the system catheter is VH Display Off.
Activating ChromaFlo
The ChromaFlo option uses patented technology to provide a visual depiction of blood
flow through the vessel. It accomplishes this by overlaying a two-dimensional color
mapping of relative blood flow velocity onto the grayscale ultrasound image. Press the
Chroma key on the control console to activate the ChromaFlo option or open the Adjust
Image dialog box and select the ChromaFlo On check box. The sensitivity and region
can be adjusted using the respective arrow keys. VH is not collected when ChromaFlo is
activated.
