Abstract
An improved method is disclosed for imaging in an interventional medical procedure that is more advanced than a conventional 2D image processing application and less restrictive than a 3D reconstruction image processing application. In contrast to the prior art 2D imaging application in which a single 2D image is acquired, the inventive method acquires and stores a set of 2D anatomical images while rotating a C-arm/X-ray source using a single injection of contrast agent. In lieu of performing a 3D reconstruction, the multiplicity of anatomical views provided by the set of 2D anatomical images adequately serve as a visual “rotatable roadmap” to perform classical 2D-roadmapping navigation. The “rotatable roadmap” assists a user to locate an ideal working view of the patient's region of operative interest.
