Treatment of pelvic ring fractures: Percutaneous computer assisted iliosacral screwing, fractures percutaneously, with the aim of decreasing the incidence of surgical complications and increasing the accuracy of screw placement. Pre-operative planning of screw trajectories is performed on a 3D model of the pelvis constructed from CT scans. During surgery, a 6D optical localizer is use

Model tags: Direct 3D tracking of heart wall motion from tagged MR images, of ventricular boundaries or tag stripe locations. Model tags were created as material surfaces which defined the location of the magnetic tags within the model. Image-derived forces acted on the model tags, while the model could also be manipulated by a small number of user-controlled guide points

3D reconstruction from projection matrices in a C-arm based 3D-angiography system,ing application has been interventional angiography. In order to obtain a three-dimensional reconstruction from a C-arm mounted X-Ray Image Intensifier (XRII) traditionally the trajectory of the source and the detector system is characterized and the pixel size is estimated. The main use of the imag

Multiscale vessel enhancement filtering,re is obtained on the basis of all eigenvalues of the Hessian. This measure is tested on two dimensional DSA and three dimensional aortoiliac and cerebral MRA data. Its clinical utility is shown by the simultaneous noise and background suppression and vessel enhancement in maximum intensity projecti

Fast quantification of abdominal aortic aneurysms from CTA volumes,ments are needed in the preoperative evaluation of candidates for minimally invasive aneurysmal repair. The user initializes starting points in the iliac artery. Subsequently, an iterative tracking procedure outlines the central lumen line in the aorta and the iliac arteries. Quantitative measuremen

3-D fusion of biplane angiography and intravascular ultrasound for accurate visualization and volumravascular ultrasound provides detailed information about the cross-sectional shape as well as the composition of vessel wall and plaque, but fails to consider the geometric relationships between adjacent images. In this paper, we present a new approach for combination of both methods to allow accur

Dense 2D displacement reconstruction from SPAMM-MRI with constrained elastic splines: Implementatioed from two SPAMM frames are brought into registration, interpolating a dense displacement vector field. The reconstructed vector field adheres to the known displacement information at the intersections, forces corresponding snakes to be warped into one another, and for all other points in the myoca
