LIVE IMAGE
With a 15cm x 15cm detector, TAU 1515 provides 25-33% larger surface area compared to conventional mini C-arms*.
Keep your focus on the patient and not the equipment by achieving preferred views with fewer shots, improving your workflow and reducing exposure to you and your patients.


A mini C-arm that
works for 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. Bilateral controls | New backlit controls are easier to see with additional buttons for upgraded functionality.
- 3. 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.

Further reduce dose with selectable pulses per second of 15 and 7.5 pps, depending upon your imaging needs.

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.
