Anatomy Revealed

TAU 2020 introduces the largest screen on a mini C-arm. Experience optimal eye comfort on a hi-bright, 1920 x 1080 resolution monitor.

Powered by Orthotouch 2.0 — the advanced touchscreen interface — with color interface, touch support, anatomical selections, and paediatric software.

Increased visibility provides more information with richer detail to quickly and accurately diagnose patients.

Over twice the size of detectors found on conventional mini C-arms*, an industry-leading 20cm x 20cm detector is displayed beautifully on the 27″ high resolution touch screen display.

Confirm joint space with accuracy, see fractures in full view, and save dose by minimizing shots so that you can work efficiently. Combined with paediatric indication, image anatomy in ways never before possible on a mini C-arm.

Intelligent Dose Reduction

Reduce your dose, not your image quality

At Orthoscan, we understand your concerns about radiation exposure and the demand for high-quality images. That’s why the TAU family includes cutting-edge Intelligent Dose Reduction that provides the best in diagnostic image quality while reducing exposure to you and your patients.

Orthoscan TAU 2020 features pulsed fluoroscopy technology, previously available only on full size C-arms. Pulsed fluoroscopy significantly reduce your dose rate compared to conventional continuous fluoroscopy — all without loss of image quality or detail.

The only mini C-arm available with paediatric indication

While Orthoscan TAU is a low dose device by design, it is also the only mini C-arm designed for paediatric use. By engaging the Optimized Dose Filter, Orthoscan TAU can reduce dose significantly in children and adults.

Additionally, the next generation CMOS technology achieves improve DQE efficiency. Free from a dependency on photon energy, these detectors allow for enhanced image brightness, decrease ramp time, and reduce dose.

Additional Features

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 so you can work with certainty.

Bilateral Controls

New backlit controls are easier to see with additional buttons for upgraded functionality.

Stepless Collimator

Introducing the industry’s first motorized collimator in a mini C-arm. With the touch of a finger, the collimator can be infinitely adjusted via the touchscreen interface to minimize radiation exposure and reduce patient dose while limiting the area of interest.

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.
