This paper proposes to utilize a patient-specific prior to augment intraoperative sparse-scan data to accurately reconstruct the aspects of the region that have changed by a surgical procedure in image-guided surgeries. When anatomical changes are introduced by a surgical procedure, only a sparse set of x-ray images are acquired, and the prior volume is registered to these data. Since all the information of the patient anatomy except for the surgical change is already known from the prior… 



Performance comparison between total variation (TV)-based compressed sensing and statistical iterative reconstruction algorithms.

For realistic neuro-anatomy, over 100 projections are required to avoid streak artifacts in the reconstructed images even with CS reconstruction, it is beneficial to distribute the total dose to more views as long as each view remains quantum noise limited and the total variation-based CS method is not appropriate for very low dose levels.

Image-guided interventions: technology review and clinical applications.

Clinical applications in neurosurgery, orthopedics, and the cardiac and thoracoabdominal areas are discussed, together with a description of an evolving technology named Natural Orifice Transluminal Endoscopic Surgery.

A comparison of similarity measures for use in 2-D-3-D medical image registration

Results show that the introduction of soft-tissue structures and interventional instruments into the phantom image can have a large effect on the performance of some similarity measures previously applied to 2-D-3-D image registration.

A new approach to computer-aided spine surgery: fluoroscopy-based surgical navigation

A new computer-based navigation system for spinal surgery has been designed by combining intraoperative fluoroscopy-based imaging using conventional C-arm technology with freehand surgical navigation principles that promises improved accuracy and safety in open and percutaneous spinal surgery.

High-performance intraoperative cone-beam CT on a mobile C-arm: an integrated system for guidance of head and neck surgery

The trial demonstrates the value of high-performance intraoperative 3D imaging and provides a valuable basis for human factors analysis and workflow studies that will greatly augment streamlined implementation of such systems in complex OR environments.

Ordered subsets algorithms for transmission tomography.

This paper introduces a simultaneous update algorithm called separable paraboloidal surrogates (SPS) that converges much faster than the transmission EM algorithm and shows that OSTR is superior to OSEM applied to the logarithm of the transmission data.

Image quality assessment: from error visibility to structural similarity

A structural similarity index is developed and its promise is demonstrated through a set of intuitive examples, as well as comparison to both subjective ratings and state-of-the-art objective methods on a database of images compressed with JPEG and JPEG2000.

A Simplex Method for Function Minimization

A method is described for the minimization of a function of n variables, which depends on the comparison of function values at the (n 41) vertices of a general simplex, followed by the replacement of
