Automated 3-D PDM construction from segmented images using deformable models
TLDR
A novel method for the automated construction of three-dimensional PDM from segmented images based on a novel deformable model technique is presented and it is demonstrated that the method accurately represents and predicts shapes. Expand
Three-dimensional display modes for CT colonography: conventional 3D virtual colonoscopy versus unfolded cube projection.
TLDR
The authors compared a conventional two-directional three-dimensional (3D) display for computed tomography (CT) colonography with an alternative method they developed on the basis of time efficiency and surface visibility, which enhances the 3D endoluminal display with improvedTime efficiency and higher surface visibility.

Classifying CT Image Data Into Material Fractions by a Scale and Rotation Invariant Edge Model
TLDR
This approach enables straightforward segmentation of 3-D CT images into objects of interest for computer-aided diagnosis and offers an easy tool for the design of otherwise complicated transfer functions in high-quality visualizations. Expand
Shape Constrained Deformable Models for 3D Medical Image Segmentation
TLDR
This work presents an approach which embeds an active shape model into an elastically deformable surface model, and combines the advantages of both approaches, and leads reliably to a very good overall segmentation. Expand
Computer-Aided Detection of Polyps in CT Colonography Using Logistic Regression
TLDR
A cross-center evaluation of the computer-aided detection system for computed tomography colonography showed that the trained CAD system generalizes to data from different medical centers and with different patient preparations, essential to application in large-scale screening for colorectal polyps. Expand
Electronic Cleansing for Computed Tomography (CT) Colonography Using a Scale-Invariant Three-Material Model
TLDR
A scale-invariant method to determine material fractions in voxels near T-junctions is presented and is shown to render an accurate representation of the object boundary without artifacts near junctions. Expand
Aspects of computer-aided detection (CAD) and volumetry of pulmonary nodules using multislice CT.
TLDR
Several studies have shown the feasibility and robustness of automated matching of corresponding nodule pairs between follow-up examinations, and tools for fast and accurate three-dimensional volume measurement of detected nodules are needed for diagnostic quality assurance. Expand
Detection of protrusions in curved folded surfaces applied to automated polyp detection in CT colonography
TLDR
A shape and size invariant method to detect suspicious regions and how only a few features are needed to achieve 95% sensitivity at 10 false positives (FP) per dataset for polyps larger than 6 mm is shown. Expand
On Normalized Convolution to Measure Curvature Features for Automatic Polyp Detection
TLDR
A new method which computes the curvatures using space-variant derivative operators in a strip along the edge of the colon, which optimizes the trade-off between noise reduction and mixing of adjacent image structures. Expand
Does a computer-aided detection algorithm in a second read paradigm enhance the performance of experienced computed tomography colonography readers in a population of increased risk?
TLDR
Although CTC with CAD detected a few more patients than CTC without CAD, it had no statistically significant positive influence on CTC performance. Expand
