3D Reconstruction of Human Ribcage and Lungs and Improved Visualization of Lung X-ray Images Through Removal of the Ribcage

Authors: Christopher Koehler and Thomas Wischgoll

Abstract

The analysis of X-ray imagery is the standard pre-screening approach for lung cancer. Unlike CTscans, X-ray images only provide a 2D projection of the patient’s body. As a result occlusions, i.e. some body parts covering other areas of the body within this projected X-ray image, can make the analysis more difficult. For example, the ribs, a predominant feature within the X-ray image, can cover up cancerous nodules, making it difficult for the Computer Aided Diagnostic (CAD) systems or even a doctor to detect such nodules. Hence, this paper describes a methodology for reconstructing a patient-specific 3D model of the ribs and lungs based on a set of lateral and PA X-ray images, which allows the system to calculate simulated X-ray images of just the ribs. The simulated X-ray images can then be subtracted from the original PA X-ray image resulting in an image where most of the cross hatching pattern caused by the ribs is removed to improve on automated diagnostic processes.

Modeling and Visualization of Cardiovascular Systems

Authors: Thomas Wischgoll

Published in: Dagstuhl Follow-Ups, Volume 1, Scientific Visualization: Advanced Concepts (2010)

Abstract

Modeling complex organs, such as the human heart, requires a detailed understanding of the geometric and mechanical properties of that organ. Similarly, the model is only as accurate as the precision of the underlying properties allow. Hence, it is of great importance that accurate measurements of the geometric configuration are available. This paper describes the different steps that are necessary for creating and visualizing such a vascular model, ranging from determining a basic geometric model, gathering statistical data necessary to extend an existing model up to the visualization of the resulting large-scale vascular models.
