We have been working on the development of a Scatter Display System (SDS) for monitoring and displaying scatterrelated dose to staff members during fluoroscopic interventional procedures. We have considered various methods for such a display using augmented reality (AR) and computer-generated virtual reality (VR). The current work focuses on development of the VR SDS display, which shows the color-coded scattered dose distribution in a horizontal plane at a selected height above the floor in a top-down view of the interventional suite. Reported is the first development of the methodology for real-time functionality of this software via integration of controller area network (CAN) bus digital signals from the Canon C-Arm Biplane System. Importing the CAN bus information allows immediate selection of the appropriate pre-calculated scatter dose distribution consistent with the x-ray beam orientation and characteristics as well as selection of the proper gantry and table graphic for the display. The Python CAN interface module was used for streamlining the integration of the CAN bus interface. Development of real-time functionality for the SDS allows it to provide feedback to staff during clinical procedures for informed dose management; the SDS can work alongside the patient skin dose tracking system (DTS) for complete clinical monitoring of staff and patient dose.
