1 Quick Start Guide to the Vevo 770 PN This Quick Start Guide provides a quick overview of the Vevo 770 and provides tips to allow users to start using the instrument and its various modes. A detailed step-by-step description of the system is available in the Vevo 770 Operator Manual. Warning: This equipment should not be connected or operated before the safety information in the Operator Manual has been read. Warning: This equipment is not intended for use on any living human being. Start-up Procedure Connect the RMV Start the Vevo 770 Attach the RMV scanhead that will be used during the imaging session to one of the connectors on the front of the Vevo 770. Note: Only the 700-Series RMV scanheads are to be used with the Vevo 770. Earlier versions of the RMV scanheads are not compatible with the Vevo Turn on the Vevo system using the breaker switch at the back of the system and then the computer standby switch on the left side of the system. 2. Turn on the monitor. 3. Wait for the Windows XP operating system to start up. The system is configured by VisualSonics to automatically log in.

Select the Measurement package to be used. 2. Select the appropriate RMV scanhead to be used. To view the properties of the selected scanhead, click View Properties to expand the Scanhead Selection dialog. To initialize the selected scanhead, click Initialize. Initialization sets up the appropriate software parameters for the selected RMV scanhead. Click Cancel or press <Esc> to exit the software startup process. 3. Once a scanhead is initialized, the Study Browser is displayed. The Study Browser is used for data acquisition and for the review and analysis of study data. 4. Click New or press <New> and fill out at least the two mandatory study information fields Operator Name and Study Name. 5. Click OK to continue with the study. The Vevo 770 will automatically start acquiring data in B-Mode. B-Mode 1. Select Setup > B-Mode Setup, or press <Mode Setup> to change 2. Press <Scan/Freeze> to start and stop data The acquired data may be reviewed using the cine loop controls at the bottom of the screen. 3. Press <Cine Store> to save the acquired B-Mode data.
