Landmark Influence Visualization in Active Shape Models

Segmentation of shapes in Magnetic Resonance Image (MRI) data is a non-trivial problem. Active Shape Models (ASM) is an approach that attempts to fit a Statistical Shape Model to landmarks. One possible approach is to let a user fit the model onto the MRI data by placing landmarks for ASM. Usually, the user can only see the global fit of the...

The Online Anatomical Human: An online browser and annotation system for real human anatomy

Human anatomy is complex in its nature and from the late bronze age to this date people have been trying to understand it. Resources such as books and software exist to train students in their knowledge of the human body. Most books focus on specific parts of the body or try to give a general overview. Images in books present the information...

Visualization for the Planning and Guidance of Minimally Invasive Cement Injection in Orthopaedics

Minimally invasive refixation by cement injection is a novel technique, performed at the Leiden University Medical Center for the revision of failed hip implants. During this procedure, the surgeon inserts needles into the periprosthetic space of the femur, to inject new cement for the fixation of the prosthesis. For that, two intra-operative...

The Unified Anatomical Human: Model-based Visualization of Heterogeneous Anatomy Data

In the course of anatomical research, anatomists acquire and attempt to organize a great deal of heterogeneous data from different sources, such as MRI and CT data, cryosections, immunohistochemistry, manual and automatic segmentations of various structures, related literature, the relations between all of these items, and so forth. Anatomical...

A Client/Server Framework for Interactive Remote 3D Visualization of Histological Data

The amount of data involved in medical volumes, especially in the case of volumes consisting of stacks of histological sections, tends to be very large. Despite rapid advancements in computer processing power and storage- and memory capacity in the past years these volumes are simply too large to be transferred to and visualized on regular...
