Mobile C-Arm System Combines Ease of Use with Dose Management Features

A new mobile surgical C-arm system meets the needs of operating and emergency rooms with easy positioning and optimal performance.

The Opescope Acteno, developed by Shimadzu (Kyoto, Japan), combines excellent imaging quality with simple operability. The counter-balanced C-arm can be positioned easily and precisely. The manual vertical C-arm movements enable much faster height adjustments in routine operations.


The enlarged 78-cm-wide C-arm facilitates approaches to the patient and reduces the risk of contact with the operating table. Nevertheless, Acteno is very compact; its small system width of only 80 cm facilitates moving through narrow doors as well as maneuvering in smaller and busy operating rooms with large numbers of surgical devices and staff. In addition, the internal cables on the C-arm ensure easy cleaning—a significant hygienic benefit.

The All-Free button at the image intensifier is a unique feature to release the electro-mechanical arrest on the C-arm. The operator can handily position the C-arm without the need to go back to the cart unit. The 1M high-resolution charged coupled device (CCD) camera, combined with the sophisticated imaging technologies of Shimadzu, provide excellent image quality. X-ray settings can be easily set via a large touchscreen on the C-arm unit, where the operator can also choose between simple mode and expert mode. Optionally, the screen can also display the fluoroscopic images.

Acteno incorporates special functions to ensure high image quality while reducing X-ray exposure, even during long surgical procedures. The functions include pulsed fluoroscopy, multibeam hardening filters, and virtual collimation on the LIH (last image hold). Furthermore, the area dose product is displayed in real-time on the touchscreen and the screen on the monitor cart.
