Rotational stereo roadmapping
First Claim
1. A computer-implemented method for imaging in an interventional medical procedure using an imaging system including a rotatable arm including a radiation emitting device located towards one end of said rotatable arm and a detector device located towards the opposite end of said rotatable arm, said detector device acquiring radiation emitted by the emitting device and having passed through a patient, the method comprising:
- (a) storing a plurality of 2D anatomical images of a region of interest in a patient'"'"'s body acquired at different rotatable arm angles and angular data identifying individual respective angles of said rotatable arm at which corresponding 2D anatomical images are acquired;
(b) receiving user entered data selecting an optimal image from said plurality of 2D anatomical images in response to presenting data to a user identifying to said user said plurality of 2D anatomical images and associated corresponding rotatable arm angles;
(c) moving a radiation source and detector to a pre-stored angular position associated with said selected optimal image using said angular data;
(d) constructing a composite image comprised of the selected optimal 2D image and a live 2D image without performing 3D image reconstruction, wherein said live image comprises a medical device displayed in real-time;
(e) displaying said composite image, wherein said composite image comprises data identifying a displayed angular position and orientation of said medical device relative to said selected optimal anatomical image of said region of interest of said patient.

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.
