The healthcare sector has been investing heavily in health information technologies (HIT), with the aim of improving decision-making through improved medical processes, reduced costs and integration of medical data. However, the overall contribution of HIT to the medical field is not obvious, especially, in high-stress environments such as the emergency department (ED). The objective of this re...

INTRODUCTION The first step in fMRI statistics is almost invariably to create a thresholded statistical map, showing which regions are ‘activated’ above some particular threshold. For simple comparisons, it is often sufficient to stop there and simply report the results of the thresholded map. However, there are often reasons to look further into particular regions of interest (ROIs). In this b...

This paper presents a method for improving the accuracy of template-based planar tracking. It has been shown that when the ROI of the input image has a lower resolution than the template, tracking accuracy will deteriorate; then, this can be remedied by blurring the template in response to the motion of the plane. In this study, we show that, conversely, when the template has a lower resolution...

In this article, we present an algorithm that selects regions of interest (ROI) containing a tumour, based on the combination of a texture and histogram analysis. The first analysis compares texture features extracted from different regions in an image to the same features extracted from known tumorous regions. The second analysis detects the ROI with two thresholds computed from the histograms...
