Abstract: Systems and methods for rendering advantageous images/views of an anatomical structure, e.g., vessel structure(s), and surrounding anatomical features/structures are provided. The disclosed systems and methods combine conventional 3D x-ray rotational angiography (3DRA) with a diagnostic scan of the relevant anatomical region, e.g., a CT or MR scan, to yield a combined image/view thereof. The image includes silhouette rendering of structures and/or vessel anatomy below the CT/MRI slab, i.e., obscured vessel structures, thereby allowing clinicians and other medical/surgical staff to develop a better understanding of vessel morphology and relationships between vessel pathology and surrounding branches/anatomical structures.

Abstract: A method of generating intraoperative 3-dimensional image data includes the processes of acquiring baseline 3-dimensional image data of a region of interest. Non-contrast 3-dimensional image data of said region, and intraoperative 2-dimensional image data of said region are also acquired. The intraoperative 2-dimensional image data and the baseline 3-dimensional image data are each aligned to the non-contrast 3-dimensionsal image data, whereby an accurate rendering of intraoperative 3-dimensional image data results from the alignment of both the baseline 3D and intraoperative 2D image data to the non-contrast 3D image data.
