Over twice the size of detectors found on conventional mini C-arms*, an industry-leading 20cm x 20cm detector takes the potential of the mini C-arm to the next level.
Confirm joint space with accuracy, see fractures in full view, and save dose by minimizing shots so that you can work efficiently. Combined with pediatric indication, image anatomy in ways never before possible on a mini C-arm.


A mini C-arm that
works with you
- 1. LED LIGHTS | Insufficient lighting during a case can make it challenging to see anatomy clearly. Unique to the Orthoscan TAU family, surgical LED lights provide additional illumination on the anatomy. Eliminate shadows cast from the C-arm and the OR so you can work with certainty.
- 2. STEPLESS COLLIMATOR | Introducing the industry’s first motorized collimator in a mini C-arm. With the touch of a finger, infinitely adjust via the touchscreen interface to minimize radiation exposure and reduce patient dose while limiting the area of interest.
- 3. BILATERAL CONTROLS | New backlit controls are easier to see with additional buttons for upgraded functionality.
- 4. C-ARM DESIGN | Focus on your case with an increased orbital rotation of 160°, larger arc depth of 20”, and improved umbilical cable. Effortlessly maneuver the C-arm to attain preferred views without stressing your patient’s anatomy.

REDUCE YOUR DOSE, NOT YOUR IMAGE QUALITY
Orthoscan TAU 2020 features pulsed fluoroscopy technology, previously available only on full size C-arms.
By imaging at 30 pulses per second, significantly reduce your dose rate compared to conventional continuous fluoroscopy — all without loss of image quality or detail.
Further reduce dose with selectable pulses per second of 15, 7.5 and 2 pps, depending upon your imaging needs.

As TAU 2020 closes the gap between mini and full size C-arms, you may wonder which class of device is right for your imaging needs.
Here are three simple advantages TAU 2020 has over full size equipment.

-
1Low dose deviceBy the nature of their design and advancements in dose reduction technology, Orthoscan mini C-arms typically emit significantly less dose than conventional full size C-arms.
-
2Easy to useOrthoscan mini C-arms are all-in-one units designed to be easily positioned and operated by one user. Multiple operators and accessories are not required.
-
3Small & portableTrue to their name, Orthoscan mini C-arms take up less space in your facility and OR. They are highly portable, making transport between rooms painless.
TAU is the name of a mathematical ratio commonly found in nature. It’s often referred to as the Golden ratio.
This ratio can be used to create aesthetically pleasing, natural-looking compositions in designs.
The TAU family was designed using this principle.
