In this paper we introduce the extendable cross-platform software framework Julius for medical visualization and surgical planning, consisting of two conceptual layers: the Julius Software Development Kit (JSDK) and its frontend the Julius Graphical User Interface (JGUI). Julius features a modular, platform-independent design and includes a full set of… (More)
For reconstruction of some craniofacial defects which m a y b e c a u s e d b y trauma, removal of cancer, or due to congenital absence, the procedure of bonegrafting is necessary. In this paper we propose a method to identify an optimal donor site for autologous grafts. It is done by performing an optimization of appropriate surface based and voxel based… (More)
In this work we present and discuss some methodological issues associated with the generation of the computer based anatomical models. The importance of the virtual patient models is becoming increasingly recognized in modern medicine. The advantages of using such biomedical virtual models are analogous to those of real system behavior simulation in the… (More)
Nowadays the process of surgical planning is a crucial point of every operation in the craniofa-cial region. In this work we focus on the planning of graft reconstructive surgery for autologous osseous grafts. The planning method consists of two stages. The non-automatic graft design step is followed by a fully automatic procedure to find the best… (More)
In this paper a new fully automatic method for registration of intramodal medical data is proposed. The method combines edge detection at diierent thresholds with chamfer distance transformation. The result is a distance map which is weighted by the importance of the edges which are extracted. As an alternative to the user-dependent non-automatic… (More)
This paper develops a framework for research in the eld of multimodality image registration. A certain formal treatment of the registration problem is proposed. We discuss some aspects of the surface and voxel-similarity measures in a context of simulated annealing based optimization.
