Conventional planning of orthopedic injuries often relies on manual
measurements obtained from radiographic images or CT slices. Computer
assisted (CA) methods can support the surgeon in the preoperative planning
to improve the reliability of the surgery. In this talk I will present
novel CA methods for the planning of two types of interventions, namely
the reduction of complex humerus fractures and the surgical correction
of deformed forearm bones. Both tasks rely on patient-specific bone
models segmented from CT. The segmentation is performed with a graph
cut approach, particularly designed to tackle common problems in bone
segmentation. For the reconstruction of humerus fractures, an interactive
approach and a semi-automatic method are presented. Interactively, the
reconstruction is carried out in an immersive, multi-modal planning
system integrating stereoscopic rendering and haptic feedback. In
the semi-automatic method, the contralateral (uninjured) bone acts
as a template to obtain an initial reconstruction. The contralateral
matching is efficiently performed using search-space sampling and
GPU-based registration. Based on this initial assembly, the most
correct reconstruction is finally computed by applying registration
and multi-piece alignment techniques to the fracture surfaces. In the
last part of my talk, the CA planning of corrective forearm osteotomies
will be described. These methods include several 3-d based techniques
for an accurate quantification of forearm deformities. Furthermore,
a kinematic model of the forearm motion is presented which provides
valuable information to the surgeon.

Das 21. Jahrhundert ist das Jahrhundert der Globalisierung. Dies gilt
auch für die IT. Systementwicklung wird immer öfter nur zu einem Teil
eines sehr viel umfassenderen Ansatzes, nämlich der Wartung und Pflege
von Systemlandschaften. Für Systemlandschaften (also große Systeme,
die wiederum aus kleineren Systemen mit unterschiedlichen Eigentümern
bestehen) gelten aber andere Regeln als für Einzelsysteme. Und genau
hier kommt SOA ins Spiel. SOA bietet Konzepte wie lose Kopplung,
hohe Interoperabilität und Service-Orientierung, die uns in die Lage
versetzen, fachliche Anforderungen, die über mehrere Systeme verteilt
sind, nachhaltig zu verwalten. ...

Searching the Web and accessing local multimedia resources, e.g. personal
music, photo or video collections, has become an every day task. However,
the currently available tools for searching and organization still provide
only very limited support with respect to interactive structuring and
visualization. In this talk, first a motivation for the need to develop
information systems which focus on user specific support in every step
of the interaction process is given. Then approaches are discussed that
tackle specific problems of this process, especially methods to structure
and visualize sets of text and multimedia objects using user specific
interests as well as structural information extracted from ontologies.

Eine Software ist das Ergebnis vieler Entscheidungen. In diesem Vortrag
wird aufgezeigt, wann im Software Engineering welche Entscheidungen
getroffen werden und wie diese durch Methodenunterstützung verbessert
werden können. Der Schwerpunkt des Vortrags liegt auf Entscheidungen
in den frühen Phasen der Entwicklung.
