Interventional volume scanner

摘要

A C-arm X-ray system is disclosed which includes an X-ray source, an X-ray detector and a support C-arm mechanism including an outer and inner C-arm. The X-ray source and the X-ray detector are oppositely disposed on the inner C-arm. The inner C-arm is suspended upon at least one wheel construction disposed in the support C-arm. The inner C-arm may be automatically driven annularly outside of a first end of the C-arm support and into a second end of the C-arm support to close a gap normally found in conventional C-arm X-ray devices. Such construction allows the X-ray source and X-ray detector to rotate at least one full 360 degree cycle, providing an C-arm X-ray device capable of performing both fluoroscopic and CT procedures without a need to move a patient under examination (i.e., monitoring the patient in a common frame of reference for both applications).
