Upgrade your expectations of mini C-arm performance

For those who desire more, TAU 1515 delivers the innovative features you expect from an Orthoscan mini C-arm.

A larger detector and live image give you the freedom to view anatomy as it needs to be seen. Pulsed fluoroscopy and other dose-saving features reduce your dose without sacrificing image quality. Pediatric indication – an industry first – broadens your patient base.

Bring new opportunities to your facility and patients with Orthoscan TAU 1515.

Detector size

Imaging evolved

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.

Intelligent Dose Reduction

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.

Pulsed fluoroscopy

Reduce your dose, not your image quality

Orthoscan TAU 1515 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 and 7.5 pps, depending upon your imaging needs.

Optimized Dose Filter

The only mini C-arm available with pediatric indication

While Orthoscan TAU is a low dose device by design, it is also the only mini C-arm designed for pediatric use .

By engaging the Optimized Dose Filter, Orthoscan TAU can reduce dose significantly in children and adults.

Next generation CMOS

Next generation CMOS imaging for the surgical market

Achieve increased DQE efficiency with the latest generation CMOS detector.

Free from a dependency on photon energy, these detectors produce low-noise images even in very low dose situations. Next generation detectors improve image brightness, decrease ramp time, and reduce dose.

Additionally, Mag Mode retains image quality without an increase in dose.

* Using Intelligent Dose Reduction (with Cu filter) when compared to Orthoscan 1000-0004-FD. In clinical practice, the use of IDR may reduce patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.

Surgeon driven design

Improved bilateral controls

New backlit controls are easier to see with additional functionality.

What’s in a name?

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.
