Z-Motion U-Arm vs. Pausch Paxis 200 U-Arm

z-motion-vs-paxis-200U-arm X-ray systems have increased in popularity over the last few years. This makes sense, as the U-arm configuration offers a high degree of scanning flexibility with a smaller footprint than more traditional rad room configurations, but with all the popularity comes a wider field of options, and with options comes more research to find the best fit. To help make that research easier, we've compared two common U-arm options on the market: the Z-Motion and the Pausch Paxis 200. Keep reading to see how they stack up.

Where the Z-motion Wins 

The Z-motion U-arm is one of the most popular systems on the market. There are quite a few reasons for this, but we'll highlight the ones we've heard the most comments on from buyers and engineers in the field.

Scanning Flexibility

The Z-Motion can rotate further (-45 to 135 degrees vs. - 15 to 115 degrees on the Paxis 200) and has a greater source-to-image distance (39"-79" vs. 40"-72" on the Paxis 200). The Z-motion also boasts a 4-way floating table while the Paxis has a static table. All these dimensions offer more flexibility in patient positioning, especially during cross table lateral studies.

Value Retention

If a facility decides to sell their Z-Motion, they can expect it to fetch a strong price on the secondary market. Used Z-Motions are a rare find and are often sold quickly when they do become available.

Safety

While the Z-Motion is one of many U-arm models that has anti-collision sensors for safety during motorized movements, it has another layer of protection other systems don't. If an object is in the arm's path and the collision sensor fails to detect it, the Z-Motion will release its motor clutch to disengage motion.

Where the Pausch Paxis 200 Wins 

At this point you may be asking what's left for the Paxis 200 to bring to the table. The answer is brief, as there's only one area where the Paxis has an edge: it costs less. In most instances, it's an alternative to the Z-motion for buyers under serious budget constraints. This isn't meant to paint the Paxis 200 as a bad system, it can suffice for low to moderate-volume settings performing the basics, but facilities expecting a fuller-featured experience would do well to look elsewhere.

The Takeaway

As with many other products, a U-arm buyer gets what they pay for. If your facility is looking for flexibility in scanning, a system that will be worth more if/when you decide to sell, and a level of safety beyond what most U-arms offer, the Z-Motion is the clear choice. If, however, you need to accomplish the basics on a tight budget, the Paxis 200 is worth considering. In either case, the Block Imaging team is ready to help you navigate the options and make the best pick for you.
