Evaluation of Automated 2D-3D Image Overlay System Utilizing Subtraction of Bone Marrow Image for EVAR: Feasibility Study

Abstract

"3D Roadmap" was confirmed to be valuable for visualization of vessel origin in a fused image and for reduction of contrast material during EVAR.

Feasibility and accuracy of fusion imaging during thoracic endovascular aortic repair

“…We learned in this study that the deviation in thoracic fusion imaging is greater than in abdominal cases compared with what is reported in the literature 6,8,10,11 and our own unpublished data. Although we assessed the aforementioned clinical failure, we think this high rate of deviation is due to the following difficulties and characteristics of thoracic procedures that change the anatomy or make registration more difficult: (Fig 7).…”

Orthogonal Rings, Fiducial Markers, and Overlay Accuracy When Image Fusion is Used for EVAR Guidance

“…Three dimensional (3D) image fusion is an advanced imaging tool that helps the operator, providing useful anatomical information for guidance during endovascular procedures. Several authors have reported their clinical experience with fused imaging during endovascular aortic repair (EVAR), suggesting that the method is feasible 1 and that it can reduce both radiation 2e5 and contrast dose. 6,7 Visualization of anatomical positions derived from pre-operative imaging can be achieved by projecting volume rendered (VR) images or specific marks on the live fluoroscopy screen.…”

New simple image overlay system using a tablet PC for pinpoint identification of the appropriate site for anastomosis in peripheral arterial reconstruction

“…Anand et al [15] introduced a preclinical mobile image overlay system for needle interventions. In vascular surgery, an image overlay system has been used in endovascular aneurysm repair [17]; however, we know of no other reports of using an image overlay system or a tablet PC in peripheral arterial revascularization.…”

“…Navigation by augmented reality using image overlay systems has been introduced in several clinical settings, including neurosurgery, orthopedics, urology, and abdominal surgery, and has shown potential utility in assisting the performance of safe and secure surgical or interventional procedures [13][14][15][16][17][18][19][20][21][22][23]. We recently devised a new medical navigation system that superimposes threedimensional (3D) models onto real-time images taken by the back-camera of a tablet personal computer (PC) [24].…”
