In the past few years, a number of two-dimensional (2-D) to three-dimensional (3-D)(2-D-3-
D) registration algorithms have been introduced. However, these methods have been …

We present a gradient-based method for rigid registration of a patient preoperative
computed tomography (CT) to its intraoperative situation with a few fluoroscopic X-ray …

Abstract Computerized Image Registration approaches can offer automatic and accurate
image alignments without extensive user involvement and provide tools for visualizing …

OBJECTIVE: New technology has enabled the increasing use of radiosurgery to ablate
spinal lesions. The first generation of the CyberKnife (Accuray, Inc., Sunnyvale, CA) image …

Generation of digitally reconstructed radiographs (DRRs) is computationally expensive and
is typically the rate-limiting step in the execution time of intensity-based two-dimensional to …

We propose a new method for aligning three-dimensional (3-D) magnetic resonance
angiography (MRA) with 2-D X-ray digital subtraction angiograms (DSA). Our method is …

The efficacy of radiation therapy treatment depends on the patient setup accuracy at each
daily fraction. A significant problem is reproducing the patient position during treatment …

The authors developed a fast and accurate two‐dimensional (2D)–three‐dimensional (3D)
image registration method to perform precise initial patient setup and frequent detection and …
