    3 months. Of course, any time you suspect a problem with an ultrasound scanner, you will want to test it immediately. CIRS recommends using a standard form to record the results of your tests, so you can be sure that each testing session is consistent and thorough. Recording your findings also provides written documentation of your QA...

    SETUP INSTRUCTIONS Parts List When you unpack the Doppler String Phantom for the first time, you should find: • Electronic Controller • Acrylic tank with motor and pulleys attached • Scanhead Clamp • Set of 5 String Loops (not pictured) •...

  • Page 6: Using The Diffuser Mat

    Using the Diffuser Mat The black rubber Diffuser Mat is provided to reduce reverberations in the tank by absorbing and scattering the ultrasound beam. Place the mat in the bottom of the tank with the ridges facing up, if desired. Installing the String If your Doppler String Phantom was shipped in a custom carrying case, the string target is already installed.

  • Page 7: Setting Up The Clamp

    Setting up the Clamp The Doppler String Phantom is shipped with a scanhead clamp system con- sisting of a clamp (see Figure 3), an "arm" with a center joint and an arm at- About Velocity Corrected tachment fixture, which is bolted to the tank. If your Doppler String Phantom Fluid: was shipped in a custom carrying case, the clamp will have been set up at the factory and you should skip step 1.

  • Page 8: Connecting The Controller

    About Scanning Angles: The best angle for most Doppler ultrasound scans is 60°. The string target in the Doppler String Phantom is set at an angle, so that a scanhead aimed straight down will be at a 60° angle to the string. Of course, you should scan at the angle that is needed for your tests.

  • Page 9: Operating Instructions

    OPERATING INSTRUCTIONS Using Constant Speeds The Doppler String Phantom can be set for constant string speeds ranging from 20 to 200 cm/sec. Constant speeds are useful for a quick check to verify that your scanner is reporting correct image registration and target velocity for the scanning angle you’re using.

    After setting up the Doppler String Phantom, turn on the power switch (located on the back of the controller). The display reads UP=H2O DOWN=H2O/GLYCOL. If the tank is filled with water, press UP. If the tank is filled with velocity-corrected fluid, press DOWN. (See About Velocity-Corrected Fluid on page 4 for more information.) The display reads SELECT A FUNCTION.

  • Page 12: Selecting Velocities And Waveforms

    Selecting Velocities and Waveforms Constant Speeds The following example demonstrates how to generate various Doppler target velocities: To create a constant flow at 52 cm/sec the following steps must be taken: <Ctrl> Z 1. Turn the controller on or enter to restart the program.

    4. Issue the following commands: C (motor starts at 10 cm/sec) S100 <Enter>. 5. The controller will increase the velocity from the initial 10 cm/sec to 100 cm/sec and hold. Read in the velocity data from ultrasound machine and compare to the phantom. This completes the procedure. Locking the Settings: To prevent the phantom settings from being changed at the front panel while operating via remote control, issue a <Ctrl>...

  • Page 14: Maintenance Instructions

    MAINTENANCE INSTRUCTIONS Making String Loops Occasionally, string loops break and need to be replaced. You can order sets of 20 preformed loops from CIRS (See Preformed String Loops for more information) or make your own loops using these instructions. In general you want your string loop to have a small unobtrusive knot that will roll smoothly over the pulleys in the tank.
