GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 4 - Functional Checks 4 - 29 4-3-4 Basic Controls 4-3-4-1 Introduction Most of the mode dependant controls can be foun d as Mode Dependant Keys (Mode Dependant Rotary Knobs and Mode Dependant Push Buttons) and Trackball. The functions available on the Mode Dependant Keys and Trackball vary according to the scan mode and position that is currently active. 4-3-4-2 Mode Dependant Rotary Knobs Vivid 7 has four mode dependant rotary knobs. The assigned functions are indicated above the rotary on the LCD display. 4-3-4-3 Mode Dependant Push Buttons Vivid 7 has five Mode Dependant Push Buttons. The assigned functions are indicated above the button on the LCD display. 4-3-4-4 More The MORE button gives access to additional contro ls on the Mode Dependant Push Buttons.

The Trackball area consist of: • The Trackball: used as a cursor control in acqu isition mode, scrolling control in freeze and as a selection tool (like a mouse cursor) in post-processing mode. • Three SELECT keys (identical): Perform the select ed control or highlighted menu item. •The TRACKBALL key: Toggles between the available trackball function assignments displayed in the Status bar. • The update menu key: enables quick access to image related functions from a pop-up menu. 4-3-4-7 Other Controls Other controls are located on separate keys (knobs a nd buttons) or groups of keys on the Operator Panel.
GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 4 - Functional Checks 4 - 31 4-3-5 Performance Tests 4-3-5-1 Recommended Test Phantoms GE Healthcare recommends the RMI 430GS phantom. It is the most current phantom recommended to our field service personnel and provides the necessary targets and extended life necessary for consistent system testing.

Connect one of the probes, to the scanner’s left-most active probe connector. -See Probe Connection on page 3-21 for info about connecting the probes. - See section Section 9-26 Probes on page 9-80 for available probes. 2.) Turn ON the scanner. -See 4-2-2 Power ON/ Boot UP on page 4-3 for info about booting the scanner. The 2D Mode window is displayed (default mode). 3.) If needed, adjust the Display’s Brightness and Contrast setting. Figure 4-27 2D Mode Screen Example Status Window Control Menu

These Image Controls are used to optimize the 2D picture: -Use Gain and TGC controls to optimize the ov erall image together with the Power control. -Use Depth to adjust the range to be imaged. -Use Focus to center the focal point(s) around the region of interest. -Use Frequency (move to higher frequencies) or Frame rate (move to lower frame rate) to increase resolution in image. -Use Frequency (move to lower frequency) to increase penetration. -Use the DDP control to optimize imaging in the blood flow regions and make a cleaner, less noisy image. -Use Reject/Adaptive Reject controls to reduce noise in the image. -Use the UD Clarity control to personalized appearance of the tissue. Moving the paddle to the left creates a smoother image, though ke eping boundaries sharp. Moving the paddle to the right creates a crisper image.

GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL 4 - 34 Section 4-3 - Functional Checks 4-3-6-3 Check Width, Focus, Framerate, Frequency These 2D Mode Functions are located on Mode Dependant Rotaries. The results of these adjustments must be verified on the 2D sector on the screen. Table 4-6 2D Mode: Check Width, Focus, Framerate and Frequency StepTaskExpected Result 1.Turn the rotary labeled WIDTH left and right. Controls the size or angular width of the 2D image sector. A smaller angle generally produces a scan with higher frame rate. 2. Turn the rotary labeled FOCUS left and right to move the focal point up and down. Changes the location of the focal point(s). A triangular focus marker indicates the depth of the focal point. 3. Turn the rotary labeled FRAMERATE left and right to adjust the Frame Rate Adjusts frame rate. Rotate the knob clockwise to increase frame rate. The relative setting of the frame rate is displayed in the status window. When adjusting frame rate, there is a trade off between spatial and temporal resolution. 4.Turn the rotary labeled FREQUENCY left and right to verify that the probe’s operating frequency can be adjusted Enables the adjustment of the probe’s operating frequency. Rotate the knob clockwise to increase the frequency. The selected frequency is displayed in the status window. For some probes/applications, the lowest frequency settings will be Octave Imaging settings.

Table 4-7 2D Mode: Check Up/Down, Left/Right, B Color Maps and Cineloop StepTaskExpected Result 1. Press once on the Mode Dependant button labeled UP/DOWN Enables the 2D image to be flipped 180 degrees. 2. Press once on the Mode Dependant button labeled LEFT/RIGHT Enables a mirror image of the 2D image to be created. The left/right reference marker V moves to the other side of the image. 3. Select B COLOR MAPS Displays a 2D Map Menu on the screen to optimize the greyscale presentation. The menu enables an option from a list of non-linear gray-curves or different 2D-colorized curves to be selected. 4.Press FREEZE Select CINELOOP ) Starts cine loop acquisition.

Adjust TISSUE GAIN Increases the overall gain equally for all depth when rotated clockwise 2. Adjust Time Gain Compensation (TGC) Compensates for depth-related attenuation in an image. The upper sliders affect the near field. The lower sliders (nearest the operator) affect the far field. 3. Adjust Depth Sets the maximum (far field) distance that will be imaged. Decreasing the depth may allow higher frame ratesTISSUE GAIN TGC DEPTH
