Configuring Your CTS-5500+

There are certain settings you are going to want to make on your ultrasound to configure it properly. Each of these is covered below. Many may already be in place (and should be in place), but if you check and they don’t match the way we spell them out here, make the suggested changes and then be sure to follow the very last step at the bottom, updating your Exam Type so as to save the changes you have made as your new default settings.

  1. Make sure you have a live image on the screen by looking to the bottom right corner and seeing if it says “Focus.” If it says “Scroll” (or pretty much anything other than “Focus”), it means your image is frozen. Just press the “FREEZE” button at the bottom right corner of your ultrasound console and that should un-freeze the image, which will change the word at the bottom right corner of your screen to “Focus.” That’s what we want while going through the next few steps.
  2. Your Frequency is listed in the box on the left of your screen. If this isn’t set to 7.5 MHz, press the “FREQ” button (to the right and above your trackball) until it reads 7.5 MHz. This will be the best default frequency for foot and ankle work.
  3. The B-Gain setting is also listed in the box on the left of the screen. (You can ignore “M-Gain”; all you will be working in is B-Mode.) A good default value for your B-Gain is 70 or 75. If it’s anything other than this, use your “B-Gain” dial (one of the five knobs on your ultrasound) and turn it to 70.
  4. Now let’s ramp up your enhancement setting, which will enhance the edges of the plantar fascia and neuromas, for instance. Here’s how to do it. Press the “T-BALL” button right above your trackball, then scroll the trackball down and look in the control box on the left side of the screen. The box will expand as you roll down, and you should then see the value for Enhancement (ENH). It’s probably set to “0” by default. Highlight that “0” and then use your “VALUE” knob (the furthest right knob on your system) to turn that ENH setting up to 3. While you’re here, glance also at the setting for “Width” and make sure that it matches the size of probe you have — if you have a 50mm linear probe, make sure it says 50mm (if it doesn’t, you can use the Value knob to change it). Now go ahead and press “T-BALL” again to save and exit.
  5. This is also a good time to set up your preferred “quick-save” image settings. This configuration of settings will make saving images later a matter of simply pressing two buttons. But first it has to be set up. Here’s how: Press the “DISK” button (which is located on the right side of your console, above the Print button). In the menu that comes up, scroll down using the trackball and highlight “Store Settings” and press “ENTER.” In the menu that now comes up you can use your trackball to select the settings you wish to choose and then press “Enter” to select them (which places a little dot next to your choice). These are the settings you want to highlight and select: Image Format = “JPEG.” CINE Format = “AVI.” Store Location = “USB Disk.” Folder Format = “Patient Name / Date.” Save Location = “Hard Disk.” With all of those set, go to the bottom and highlight “OK” and press “Enter.” This should take you back to the little menu. Press escape (“ESC”) to escape out of that. You’re all set now to save your images later using the quick-save method.
  6. Now just a little housekeeping left … Your name (or your practice name) should be displayed at the top left corner of the screen. If it’s not printed up there the way you want it, click here.
  7. The date and time is listed up at the top right corner of the screen. If that’s incorrect, click here.
  8. The exam type is listed at the bottom left corner of the screen, below “ID” and “Patient.” If this says “Thyroid” (which is sometimes the default), then we are going to need to change it. If you are a podiatrist, for example, and it doesn’t say “Podiatry” down there, you’re going to want to create a “Podiatry” custom exam type, in which case you will want to click here. If it already says “Podiatry,” we’re still going to want to update the exam type to save all of the settings we’ve just changed around. To do this, press “EXAM” (two buttons to the right of your space bar), and then scroll down to highlight the “Podiatry” exam type. With that highlighted, press the letter “U” (for “update”) and when the little box pops up, you’ll press “Enter” to confirm that you want to update the exam type. This will save all of your new settings as your defaults.
  9. Once your exam type is set up, you can even create a menu of custom annotation words and phrases that will speed up making notations on your images. The instructions on setting up this menu are available by clicking here.
