The Representative will give you an unlock level number and an digit unlock code. Page Chapter 3 Setting Up Patient Information When you save an image, the Terason software puts it in a folder for the specific patient, along with a patient information file.
If you do not enter patient details, the image is stored in a folder with other images and is not associated with a specific patient. In that folder, the Terason software stores the Patient Info file and all saved scans for that patient. Page 59 Click the Save button or click the Image Display tab to save the entered information and open the scanning window. The Image Display window is ready for you to conduct the exam.
The patient information is shown across the top of the window and is saved with scanned images you create for the patient. If the folders contain any saved images, those files are also deleted. Page 62 1. Click The Terason software prompts you to verify that you really want to delete the folder and all its contents.
Using either method also shuts down the console. Page Connecting A Transducer 2. Insert the transducer connector into the port as far as it will go. Move the locking lever to the locked position. If the Terason software is running, it detects the transducer and displays its name on the imaging window.
If the software is started after the transducer is connected, the Terason software will detect and display the transducer name as soon as it starts. Complete these steps to switch between transducers: 1. If necessary, save the active image or image loop. See Saving Images and Loops page for instructions.
If you use more than one Terason transducer, click the Image Display tab for the needed transducer. Load or create the patient information. See Chapter 3, Page 67 4. In the 2D Image Control tab, select an exam type from the Exam menu.
Choosing an Exam Type The Terason software loads preset image control settings that are optimized for the selected exam and the connected transducer. See Chapter 8, Page Freezing Images When you freeze an image, you can use the buttons on the Playback toolbar or the arrow keys to review an entire loop, frame by frame, to find a specific frame.
You can also use the Playback buttons when viewing a saved loop. Prospective acquisition captures a loop of live scan following the acquire command, while retrospective acquisition saves a loop of a frozen scan. Page Determining Image Status. Determining Image Status The Terason software continually displays an image status message at the bottom right of the main window, next to the frame rate if displayed for the Image Display window.
In the example below, the message shows beneath the Modes toolbar. You can also drag the border between the Image Display window and an adjacent window to show less of the other window. The Status Bar menu item hides or shows the status bar at the bottom of the imaging window.
If either of these conditions occurs, call Terason for assistance. The TeraVision level numbers range from 0 to 6 or 8. All currently supported transducers have level numbers 0 through 6, except for the 4V2, which has 0 through 8.
If you choose a large text size, the text may overlap the image. If you choose a small text size, the text may be difficult to read. For example, you can acquire a scan for the patient, select Split Screen, and then acquire another scan from a different angle or location. Page 80 for information on saving images and loops. When you exit Split Screen mode, the Terason software keeps the acquired data for the active screen the one with the cyan lines at the top and bottom and discards the acquired data for the other screen.
If the image has been saved, retrieve it from the Terason Explorer window. See Finding Stored Images and Loops on page for instructions. Page 82 This check box has no affect on text already added to the image. Click any text to add it to the image. To add the Patient Position, select the appropriate position from the pull-down menu. Page 83 Chapter 4 - Acquiring Images Working with Annotations When you click a position, the Terason software adds that text at the home position.
When you add a Patient Position, you can then click the blue arrow to add the shown patient position to the image usually used for subsequent scans during an exam. Page 84 In addition to choosing from the provided text phrases, you can type any text you want onto an image. You can only add text to the 2D Image Display window.
You cannot add text to the Time Series window. Page 85 The Terason software lets you edit text added to the image using the Annotation window, or that you manually typed onto the image. Double-click the text you want to edit. The Terason software places the text cursor at the end of the text and opens the Annotation window showing the Text tab.
Click the view for the body marker you want. The Terason software adds the icon to the scan and closes the Annotation window.
The pink rectangle within the marker icon indicates the precise location. Click the an icon in the Body Marker pane. The Terason software updates the icon shown in the body marker and closes the Annotation window.
Moving the Indicator You can move the pink marker to anywhere on the icon to more precisely indicate the scanned anatomy. Page Rotating The Indicator 2. Click and move the pointer until the pink rectangle is in the desired orientation. Click to lock the rectangle in position. All other modes available in the Terason Ultrasound System software include the 2D functions, and also include an additional tab or tabs with image controls for the selected scan mode.
Page Using 2D And I. Controls You can only adjust these image controls during live scanning. When you freeze a scan, the Terason software replaces the 2D tab with a 2D Measure tab, for making measurements on the scan image.
See Chapter 7 - Working With Measurements. Page 91 Choosing an Exam Terason provides customized exams for scanning different types of anatomy. When you choose an exam, the Terason software loads image controls settings on the 2D and I. Page 92 To set a patient size, click the appropriate T-shirt symbol. Patient Size Controls You can also click on the Image menu and choose a size from the menu. Page 93 You can decrease the depth to enlarge the display of structures near the skin line, or to not display unnecessary areas at the bottom of the window.
When you select an exam type, the Terason software enters a preset depth value for the specific exam type, transducer, and patient size. Page 94 You can also use the Image menu to set the depth. To do so, complete these steps: 1. The Set Depth dialog box opens. Select a depth value from the menu. Adjusting the Gain 2D gain allows you to increase or decrease amplification of the returning echoes, which increases or decreases the amount of echo information displayed in an image.

When you select an exam type, the Terason software sets the gain to a preset value for the specific exam type, transducer, and patient size. To decrease the gain, click the slider and drag it to the left. To increase the gain, click the slider and drag it to the right.
Page 97 Linear transducers do not support LGC. These segments are arcs one eighth of the full width of the scan. Adjusting LGC can enhance imaging of the cardiac wall with some scanning orientations. Page 98 Tissue harmonic imaging processes a returned harmonic signal to enhance the displayed image. The harmonic used for THI is twice the frequency of the transmitted signal. Page 99 When Omni is on, the word Omni shows in the scan information display, and the focus markers on the depth ruler change to this: To turn Omni on or off, click the Omni button on the 2D Image Control window.
Page Controls On The I. Image Control Window The following figure shows the I. The following figure shows the effect of using the invert buttons. Page By default, the Terason software uses the Gray color scheme for 2D images. The Terason software provides several alternate schemes. To determine if another scheme improves visibility of the anatomy being scanned, cycle through the available options. Page 0 to 7.
You can also select to choose a different setting. In the example, the third item is the Map value. Page A number to the left of the slider indicates the amount of compression, from to Drag the slider to the right to increase compression, which darkens the image, or drag the slider to the left to decrease compression. Page Using The Console 35 for more information on using the console. Each large tick mark represents one second. Click on the ultrasound cursor.
The ultrasound cursor turns green, and a curved arrow replaces the finger pointer. Page Using The Console — the leftmost up and down buttons control the setting in the leftmost box, and so on. Console Controls on page 35 for more information on using the console. This depends on whether you are scanning in simultaneous or non- simultaneous mode, which is controlled by the Update button.
Page Adjusting The Wall Filter For example, if the wall filter setting is 40, each time you click the right or left arrow, the Terason software adds or subtracts 10 Hz from that value, until the selected value falls into a lower or higher range. When you type this character, the Terason software highlights the Steering Angle value and you can use the left and right arrow keys to change the value. If you press the key twice quickly, the Terason software highlights the Correction Angle.
You can also type a period. Place the Windows pointer inside the vessel of interest. You can use the Zoom tool see Enlarging an Area of the Image on page 73 for more precise pointer placement. Right-click the vessel of interest. The shortcut menu opens. The Terason software locks the sample volume indicator in the position where you right- clicked and adds the Time Series window for PWD mode.
You can now adjust the SV size, depth, or correction angle as needed for the scan. If you are already in PWD mode, moving the gate position does not interrupt the Time Series window display. Page Adjusting Noise Rejection Adjust the sound volume of the signal to a comfortable level. If it is too high, system noise may interfere with the sound produced by the blood flow. Drag the slider to the left to lower the volume. Drag the slider to the right to raise the volume.
When is selected, the Terason software continuously updates Update the 2D scan while acquiring Spectral Doppler data. When not selected, the Terason software freezes the 2D data while acquiring Spectral Doppler data.
When Update selected, the button appears pressed in and is a lighter shade than its surroundings. Note: CWD is not available when the Pwr mode is selected.
Page Adjusting The Scan Area 1. Position the Windows pointer over one of the corners of the border defining the scan area. Click a corner. Move the mouse or trackball until the scan area is the desired size. Page Inverting The Doppler Display Color Invert For example, if the PRF setting is , each time you click the right or left arrow, the Terason software adds or subtracts Hz from that value, until the selected value falls into a lower or higher range.
Page Adjusting The Wall Filter You can adjust the color gain to increase or decrease the amplification of the returning signal being played or displayed. Page Adjusting The Color Priority Due to the current high level of color persistence, when saved images are reviewed, they will not appear exactly as saved.
Page Adjusting The Color Baseline You can see the effect of your change on the color reference bar. The color maps are designated A through F in the menu. Some maps use more colors than others, and some display in a smoother gradient than others. Page Region Of Interest However, you can move the range gate, as follows: position the Windows pointer in the 2D image where you want to set the range gate, then double-click. When you set the new location for the range gate, the Terason software centers the region of interest around the new location.
You can email image and loop files or include them as graphics in other applications. When you do, the Terason software saves the active screen as an image loop, and the other screen as a single frame. Page Finding Files in the Terason Explorer on page If you open an image file and then save it again, the Terason software creates a new file; it does not overwrite the original file. To overwrite the original file, use the Export item on the File menu option and select the original file before you click the Save button.
If you selected a file format other than the Terason format, choose an Image Size from the menu. More pixels in an image produce a larger file. Fewer pixels produce a lower-quality and smaller file. Locating Saved Images and Loops To open a folder, click the symbol or double-click the folder name. Page Terason software is running, right-click in the Terason Explorer window and select to update.
Refresh The Terason software loads the selected image file into a new tab in the Image Display window. Page Click and drag in a scroll bar to see a different part of the image. When you select a dated folder in the Terason Explorer either for a specific patient or in the Image folder , the Review window automatically displays thumbnail images for all files in the selected folder. Page Browsing To Find Files However, if you have archived images, or if the images are stored elsewhere for any reason, you can still use the Terason Explorer or the File menu to locate those files.
To locate files that were not saved in the Terason default folder, complete these steps: 1. Only files in the default directory display in the Terason Explorer window, and you may have difficulty locating other files. Typically, you only move files when you are archiving older files that you do not need on your computer.
Page Renaming Files 4. Type a new name and press Enter. Deleting Files Terason recommends that you delete unnecessary files to free up disk space.
You cannot directly delete patient info files using the Terason Explorer; you can only delete folders and image or loop files. Click the file that you want to delete, or click a folder to delete all files within the folder.
Page Editing Images And Loops The types of modifications you can make depend on whether you are working with an image or a loop. The Terason software can edit only Terason Image Format files and loops.
You can use the Terason software to view images saved in other formats, but not to edit them. The Terason software creates a new file. The smaller the number of images, the larger each image prints. To change the number of images per Page Printing From The Print Preview Window If you only want to print some of the images, hold the Ctrl key down and click the images you want to print.
The Terason software draws a blue line around selected images, and when you click the Print button, the software prints only the selected images.
