Computer Assisted Interventions

We present the idea of a user-interface concept, which resolves the challenges involved in the control of interventional C-arms for their constant repositioning during surgery. The aim is to shift the paradigm of interventional image acquisition workflow from the traditional control device interfaces to a Desired-views control. This allows the interventionalists to only communicate the desired outcome of imaging, while the system takes care of computing the positioning of the C-arm imaging device relative to the patient.

The Desired-views interface will ensure a decrease in the number of C-arm repositions and total number of acquired X-ray images. Consequently, we are expecting a significant decrease in both radiation exposure and contrast injection intraoperatively.
