Automatic 2D/3D-Registration of Cerebral DSA Data Sets
نویسندگان
چکیده
We present a method to automatically register cerebral 2D digital subtraction angiography sequences (2D-DSA) to 3D rotational Xray angiography (3D-RA) volumes. The application is the validation of blood flow simulations for aneurysm treatment. We compute projection images of 3D-RA data sets and compare them to the 2D-DSA images. A three-step strategy is presented to calculate the registration where no user interaction is needed. We tested the accuracy of our method on studies of five patients by manually setting fiducial markers and measured a root mean square projection error of 1.78mm ± 0.45mm.

Intensity-based Registration of 2D-DSA and 3D-DSA Data Sets for Flow Simulation in Intracranial Aneurysms
We present a method to automatically register 2D cerebral digital subtraction angiography (DSA) images to 3D-DSA volumes. The method can be used for validation of flow simulation results and surgery planning. The algorithm was tested on clinical studies of six patients.
متن کاملComparison of 2D and 3D digital subtraction angiography in evaluation of intracranial aneurysms.
BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is considered the criterion standard for depiction of intracranial aneurysms, it is often difficult to determine the relationship of overlapping vessels to aneurysms when using 2D DSA. We compared 2D and 3D DSA in evaluation of intracranial aneurysms. METHODS Thirty-six consecutive patients with cerebral aneurysms underwent...

RATIONALE AND OBJECTIVES The purpose of this study was to evaluate the accuracy and speed of a new, semiautomatic method of three-dimensional (3D)-two-dimensional (2D) vascular registration. This method should help guide endovascular procedures by allowing interpretation of each digital subtraction angiographic (DSA) image in terms of precreated, 3D vessel trees that contain "parent-child" conn...

BACKGROUND AND PURPOSE Time-resolved 3D-DSA (4D-DSA) enables viewing vasculature from any desired angle and time frame. We investigated whether these advantages may facilitate treatment planning and the feasibility of using 4D-DSA as a single imaging technique in AVM/dural arteriovenous fistula radiosurgery. MATERIALS AND METHODS Twenty consecutive patients (8 dural arteriovenous fistulas and...
متن کاملRegistration of 3D Angiographic and X-Ray Images Using Sequential Monte Carlo Sampling
Digital subtraction angiography (DSA) reconstructions and 3D Magnetic Resonance Angiography (MRA) are the modalities of choice for diagnosis of vascular diseases. However, when it comes to treatment through an endovascular intervention, only two dimensional lower resolution information such as angiograms or fluoroscopic images are usually available. Overlaying the preoperative information from ...
