Abstract:
Rheumatoid
arthritis is an incurable disease affecting predominantly peripheral
joints of the appendicular skeleton. It can lead to severe disabling
mutilations and even to the complete destruction of the joints.
Active shape models (ASMs) are a frequently used tool in medical
image analysis. They efficiently search images with a flexible and
compact model using a priori knowledge derived from training data.
It is possible to recognize objects with high variation in shape and
appearance. The result provides a parametric description of the
identified shape.
In this lecture an introduction to the
concept of active shape models is given. In the context of
rheumatoid arthritis treatment a combination of ASMs and more
flexible active contour models (snakes) is discussed. Ultimately the
combination aims at a automated quantification of defects of
anatomical structures.
