The newest features on the Evo include: virtual collimation and zero dose digital rotation. The Evo (fixed anode) and the Evo-R (rotating anode) are mobile imaging systems designed to meet the requirements of the most demanding users. Existing in several versions, the Evo and Evo-R cover the following applications: * general surgery * orthopedic, pediatric, abdominal and neurosurgery * urology in combination with lithotripter * traumatology * digital subtraction angiography (DSA) The Evo Evo-R are equipped with state-of-the-art components and include a microprocessor controlled high frequency generator associated with a stationary or rotating anode with a high resolution image intensifier: 9” (23 cm) triple field. The generator enables all modes: continuous fluoroscopy, pulsed fluoro “snap-shot” and radiography. A cassette holder permits the user to take 24x30 cm images on cassette film, and a video printer can be provided to print the displayed images, as well as those stored in memory.
