During fluoroscopic image acquisition the Border Detection Module (BDM) monitors the location of the x-ray image area with respect to the detector borders. If the imaging area exposes the detector borders due to intentional or unintentional movement of the x-ray source or detector then image acquisition is halted by disabling output from the x-ray source.  An error message is displayed along with the last frame of captured fluoroscopic data. The operator is then instructed to realign the x-ray source or detector.

​

The alignment application employs a series of interlocks that prevents radiation exposure if the exposure area is not confined within the area of the detector at any time before or during emission of radiation. This provides a degree of radiation exposure safety to the patient that is unprecedented. Over collimation or mis-alignments with traditional C-Arm systems are virtually impossible to detect by the user and are only noticed and corrected during annual inspection. Utilizing an inscribed border zone validates alignment, this ensures any mis-alignments or over collimations are identified immediately and radiation is stopped, thus providing a considerably higher degree of safety. ​

Virtual C technology is like no other fluoroscopic system. The technology does not require pulsed radiation (pulsed fluoro). Virtual C instead works with radiographic exposures (radiographic fluoro). This novel technology breakthrough is the subject of 40% to 70% less radiation dose compared to pulsed fluoro (C-Arm) systems.

An demonstration of how this works is shown in below video.
