INTRODUCTION TO VIRTUAL C TECHNOLGY AND MACHINE VISION COLLIMATOR (MVC)​
​
Virtual C technology is like no other fluoroscopy systems, the technology does not require pulsed radiation (pulsed fluoro). Virtual C instead works with radiographic exposures "Radiographic Fluoroscopy". This novel technology breakthrough is the subject of 40% to 70% less radiation dose compared to pulsed fluoro (C-Arm) systems.
​
At its core, the Virtual C System is a mobile imaging system that acquires, processes & displays both static radiographic images & dynamic radiographic images, such as multi-rad and radiographic fluoroscopy. What sets the Virtual C apart from traditional imaging systems and methods utilizing a physical C/U-arm, is that the Virtual C allows for dynamic image acquisition without the limitations of a mechanical linkage between the X-ray source and X-ray detector.
-
Currently, physical C- or U-arms are used to ensure the alignment of imaging components during image acquisition; the physical linkage of the components has proven problematic in a number of use scenarios, often putting critical care patients at a disadvantage due to the machine’s physical limitations.
-
PortaVision’s Virtual C system instead relies on our novel, patented Machine Vision Collimator (MVC) & Custom Detectors
-
A radiographic X-ray system, MVC, and custom radiographic/fluoroscopic detector, in combination come together to create the Virtual C System & eliminate the restrictions and obstacles of traditional C-arm imaging.
The MVC Utilizing four independent shutters to automatically position the radiation beam, the MVC ensures the area of exposure always remains within the confines of the active area of the detector, eliminating the need to physically link the components. A visual display provides real-time video of the patient, with a shaded area appearing on the video image to indicate the location and size of the radiation beam with respect to the patient. Additionally, the angle and inclination of the X-ray source is displayed to the operator on the display as well.
