The development of software that would be to image understanding systems what expert
system shells are to expert systems has been the subject of considerable enquiry over the …

Explicit segmentation is required for many forms of quantitative neuroanatomic analysis.
However, manual methods are time‐consuming and subject to errors in both accuracy and …

Human investigators instinctively segment medical images into their anatomical
components, drawing upon prior knowledge of anatomy to overcome image artifacts, noise …

Modern neuroscience is providing profound insights into nature's most mysterious puzzle--
the human brain--while applications of information and computer science are transforming …

We present a knowledge-based approach to segmentation and analysis of the lung
boundaries in chest X-rays. Image edges are matched to an anatomical model of the lung …

Phalangeal osteosonogrammetry was introduced as a method for bone tissue investigation
in 1992. It is based on the measure of the velocity of ultrasound (amplitude‐dependent …

This work presented in this thesis was performed at the Montreal Neurologicallnstitule (MNI).
directed by Drs Alan Evans and Terry Peters. Herein are addressed two problems common …

Accurate planning of radiation therapy entails the definition of treatment volumes and a clear
delimitation of normal tissue of which unnecessary exposure should be prevented. The …

This paper proposes a methodology that enables an arbitrary 3-D MRI brain image-volume
to be automatically segmented and classified into neuro-anatomical components using …

Ultrasound (US) waves are mechanical vibrations that are applied to a material—bone
tissue—in order to study its properties, that is, density, elasticity, and structure. In this study …
