Software system for calibrating examiners in cephalometric point identification.

Introduction: The literature has shown that subjective concepts lead to interobserver variations in the definitions and identifications of cephalometric landmarks. Observers must be trained and calibrated to conduct scientific research using cephalometric comparisons. In this study, we aimed to develop and test a computational model called Cyclops cephalometry in radiographic cephalometry training and calibration.

Recording and reenactment of collaborative diagnosis sessions using DICOM.

This paper presents a radiological collaborative tool capable of direct manipulation of Digital Imaging and Communications in Medicine (DICOM) images on both sides, and also recording and reenacting of a recorded session. A special collaborative application protocol formerly developed was extended and used as basis for the development of collaborative session recording and playback processes. The protocol is used today for real-time radiological meetings through the Internet.

A computational method for the estimation of atrophic changes in Alzheimer's disease and mild cognitive impairment.

Early diagnosis and objective monitoring of disease progression are essential for the development of therapeutic strategies in Alzheimer's disease (AD). Current techniques are mainly based on semi-objective measures such as neuropsychological tests and a physician's magnetic resonance imaging (MRI) inspection. We have developed a computational method for automatic and unbiased assessment of the brain's state of atrophy from MRI.
