- Page 3 Setting Up/ Before You Start Plug your TOE probe into the system and Press the “PROBE” icon on the touchscreen to activate your 6vt TOE probe. The available presets will be listed under this probe – the machine will automatically default to the probe at the top of the list.
- Page 4 Approved products should be used according to manufacturers guidelines however cleaning agents must not come into contact with the probe system connector plate (7).If you have any other questions regarding cleaning agents or the cleaning procedure contact your GE representative or refer to the TEE User Manual for technical guidance.
- Page 5 Single Plane imaging - Angle and Rotate The Angle button is available on both the console and the touchscreen (Quick Rotate). Pressing either will steer the angle of the probe internally at 30 degree intervals. Pressing “Clear” on the console will take the angle straight back to zero. Use the “Rotate”...
- Page 6 Rotating and Tilting – Biplane Mode • The “Rotate” knob rotates all images together. • Scan Plane 1 and 2 can be rotated independent of each other and Scan Plane 2 can also be tilted. • The “Angle 1” rotary knob adjust’s the angle increment of Scan Plane 2. •...
- Page 7 Multi–D - Biplane Mode V Planes Image a situation where you might normally need to move the TOE probe to get a particular view I.e. moving Trans-gastric to get a short axis. V-Planes tilt the scan plane down reducing the need to move the probe.
- Page 8 Multi D - Triplane Features • Change to Triplane on the touch screen (default is to Biplane) • Move probe as needed so that you can clearly see all three views. • In Tri-Plane the third scan plane (A2 or Angle 2) is represented by a green line - to change the angle of the third image press the “Angle 1”...
- Page 9 Obtaining larger 4D volumes Enter your 4D image by either pushing 4D on the console or pressing Medium or Large on the touch screen (selection dependant on volume size required). You may like to consider a reduction in Frequency to assist with improving the Penetration for your larger volume. To acquire a 4D dataset valves,...
- Page 10 4D Zoom Hit 4D Zoom Prepare on the touchscreen and you will be taken to a biplane image as per below Adjusting Zoom region of interest -The trackball will default to Position adjustment in the Azimuth plane (The left box). Pressing the trackball Set key changes the ROI box between the position and region size adjustment.
- Page 11 4D Zoom with Flexi Zoom – Fast, flexible visualization of the heart structures The 4D zoom buttons provide quick live access to main heart structures, with no need for further volume cropping or rotation. To begin – obtain the ASE/SCA standard view & enter via the 4D Zoom Prepare button and follow the steps in the 4D zoom section.
- Page 12 Using the 4D zoom TOP DOWN button 4D zoom Top Down is helpful for any structure you wish to see from the Top – down, this makes it especially helpful for 4D left atrial appendage and interatrial septum acquisition. Adjust Zoom region of interest - The trackball will default to Position adjustment in the Left box (it is highlighted in yellow).
- Page 13 Acquiring 4D Aortic valve using Enface Left/ Right The Enface Left/Right Flexi Zoom buttons allow you to quickly view the image displayed in either the left or right 4D zoom plane in 4D – to access press either Enface Left or Right once you have optimized your ROI boxes.
- Page 14 Flexi Views – 4D acquisitions made easy Provides one touch access to factory defined views or user created views for faster, easier workflow. To select or create new Flexi Views press the subtab on the touchscreen. Available views are specific for each probe preset – press Configure on your Flexi Views touchscreen to be taken directly to the configuration screen seen below.
- Page 15 2 Click Crop 2 Click Crop allows the user to create a parallel crop on any structure. 2 Click crop can be entered into live or post image acquisition. To enter press 2Click Crop on the touch screen. To use simply place the cursor where you wish to begin and start by clicking the mouse key and scroll the trackball to begin your crop Until a second point is finalized the angle of the cropping direction can be moved by moving the trackball.
- Page 16 Flexi-Slice Flexi-Slice is used to extract 2D cut planes from the 4D dataset. To start Flexi-Slice – press the Flexi-Slice button on the touch screen while in 4D or 4D colour. You will be taken to an image similar to below displaying both 2D slices and a rendered 4D image. The layout displayed can be altered by using the Layout button.
- Page 17 Flexi-Slice tools Lock Slices Allows you to rotate the slices whilst maintain a 90 degree angle between them Rotate 4d Rotates the 4D image and the active slice while other slices remain unchanged Rotate All Rotates the 4D image, the active slice and the lines. In Flexi-Slice mode each cut-plane may be rotated or translated using the Trackball.
- Page 18 To Make Adjustments in Flexi-Slice Rotate Image Drag to translate Rotate Cut Plane Plane 1) Place the cursor at one of the extremities of a cut-plane intersection line in one of the cut- planes. The cursor will change to a .
- Page 19 4D Colour To achieve a well optimised 4D colour image it is helpful to first optimise the Colour box size and position in 2D mode. Biplane mode may further assist with optimal size and positioning. Enter into 4D using either the 4D or 4D Zoom Prepare button. If you wish to adjust your Colour gain while in 4D ensure the 4D CF tab is currently active on the touchscreen and then adjust the Active Gain knob.
