Objective quantification of the vocal fold vascular pattern: comparison of narrow band imaging and white light endoscopy.

No clinical standard procedure has yet been defined to quantify the vascular pattern of vocal folds. Subjective classification trials have shown a lot of promise. Narrow band imaging (NBI) as an endoscopic imaging tool is useful, because it shows the vascular structure clearer than white light endoscopy (WL) alone.

Occlusion-free Blood Flow Animation with Wall Thickness Visualization.

We present the first visualization tool that combines pathlines from blood flow and wall thickness information. Our method uses illustrative techniques to provide occlusion-free visualization of the flow. We thus offer medical researchers an effective visual analysis tool for aneurysm treatment risk assessment.

3D Regression Heat Map Analysis of Population Study Data.

Epidemiological studies comprise heterogeneous data about a subject group to define disease-specific risk factors. These data contain information (features) about a subject's lifestyle, medical status as well as medical image data. Statistical regression analysis is used to evaluate these features and to identify feature combinations indicating a disease (the target feature).

Combined Visualization of Wall Thickness and Wall Shear Stress for the Evaluation of Aneurysms.

For an individual rupture risk assessment of aneurysms, the aneurysm's wall morphology and hemodynamics provide valuable information. Hemodynamic information is usually extracted via computational fluid dynamic (CFD) simulation on a previously extracted 3D aneurysm surface mesh or directly measured with 4D phase-contrast magnetic resonance imaging. In contrast, a noninvasive imaging technique that depicts the aneurysm wall in vivo is still not available.

Experimental investigation of intravascular OCT for imaging of intracranial aneurysms.

Purpose: Rupture risk assessment of an intracranial aneurysm (IA) is an important factor for indication of therapy. Until today, there is no suitable objective prediction method. Conventional imaging modalities cannot assess the IA's vessel wall.

Computer-aided diagnosis in breast DCE-MRI--quantification of the heterogeneity of breast lesions.

Purpose: In our study we aim at the quantification of the heterogeneity for differential diagnosis of breast lesions in MRI.

Materials And Methods: We tested a software tool for quantification of heterogeneity. The software tool provides a three-dimensional analysis of the whole breast lesion.
