Compare ultrasound scan images of popular portable systems.
The eBit 50 was just FDA approved, so we did not have it at the time of the original comparison. Sorry the images aren't exact matches.
We had a great opportunity to compare five of the best portable ultrasonography systems recently.
Having systems side-by-side and on the same patient is the best way to compare image quality.
These images are best viewed in "Full Screen Mode" on a desktop computer. This way you can view all five of the systems images simultaneously and the are large enough to see subtle differences.
For the test, I used each company's high frequency linear arrays for the ultrasound scan.
In the order the images are displayed, I imaged my:
1. Median nerve at the wrist. Note how well you can see the fascicles.
2. Common extensor tendon at the lateral epicondyle, There is a partial tear at the insertion. Look for the dark area in the left portion of the image. Can you spot a calcification next to the tear?
3. Supraspinatus tendon of the shoulder in long axis, with a partial tear at the articular surface (note the bony irregularity on the articular surface)
4. Medial meniscus of the right knee. Partial tear with a small cyst is seen
5. Anterior hip was imaged with the high frequency linear array to evaluate the penetration capabilities with the linear probe
6. Since these systems are often used to guide needles, I tested each of them using each company's needle visualization software or beam steering. Some were quite challenging to use and image the needle well. The Konica Minolta was the easiest needle viz software to use. You only had to turn it on. No adjusting the system for the projected needle angle. As a side note, the Konica can use the needle viz on the curved array transducer as well. Impressive! I have not seen any other system that can do that.
7. I imaged a Gammex 403 GS E Multi-purpose Gray Scale Imaging Ultrasound Phantom. The phantom has pins spaced varying distances apart to determine axial and lateral resolution.

The pins at 3.5 cm's are the pins I optimized the focal zone to (M-Turbo doesn't allow focal adjustment) on each system.The challenge for the systems is to resolve each individual pin sharply.
I tried to make all things equal. Nothing perfect, but this should allow a good comparison and aid in your decision. In my mind,I weight image quality as 80 percent of the decision. It's what makes the tool of ultrasound the valuable. It helps your diagnostic confidence, can decrease the amount of time spent doing a procedure and will likely extend the time before you end up upgrading your system. A little extra spent to get better resolution, pays big benefits in the long run. Enjoy!
