Cerebral vasospasm after tumor resection. A case report.
OBJECTIVE AND IMPORTANCE Symptomatic cerebral vasospasm can occur after resection of tumors in or adjacent to the basal cisterns, causing delayed neurological deterioration. This potentially… Expand
Effects of positive resection margin and tumor distance from anus on rectal cancer treatment outcomes.
PURPOSE Rectal cancer outcome depends on stage, technical aspects of surgical excision, and use of adjuvant chemoradiation. Here, we examine effects of positive resection margin and tumor distance… Expand
Profound Hypothermia and Circulatory Arrest with Skull Base Approaches for Treatment of Complex Posterior Circulation Aneurysms
Summary Objective. Cardiopulmonary bypass with profound hypothermia and circulatory arrest has seen a resurgence as an adjunct technique in neurological surgery. We report our experience with this… Expand
On the use of singular value decomposition and decimation in discrete-time band-limited signal extrapolation
The problem of extrapolating a band-limited signal in discrete time is viewed as one of solving an underdetermined system of linear equations. Choosing the minimum norm least-squares (MNLS) solution… Expand

A new image quality metric consistent with the properties of the human visual system is derived. Using the EM algorithm, the authors restore a blurred image and quantify the improvement in image… Expand
Coincident bit counting-a new criterion for image registration
A similarity measure based on the number of coincident bits in multichannel images is presented. The similarity criterion incorporated in the image registration algorithm uses a coincident bit… Expand
Hypothermic circulatory arrest in neurovascular surgery: evolving indications and predictors of patient outcome.
Simulation of quantum mottle in digital angiographic images
A method is described for the computer simulation of quantum mottle in digital angiographic images obtained through an image intensifier (II) based system. The model corrupts a "perfect" image-one… Expand
