TLDR
A new approach to medical image analysis that combines deformable model methodologies with concepts from the field of artificial life is introduced, including a "corpus callosum worm" that can overcome noise, incomplete edges, considerable anatomical variation, and interference from collateral structures to segment and label the corpusCallosum in 2D mid-sagittal MR brain images.About:

Use of maximum intensity projections (MIP) for target volume generation in 4DCT scans for lung cancer
TL;DR: MIPs are a reliable clinical tool for generating ITVs from 4DCT data sets, thereby permitting rapid assessment of mobility for both gated and nongated 4D radiotherapy in lung cancer.

Watershed segmentation using prior shape and appearance knowledge
Ghassan Hamarneh,Xiaoxing Li +1 more
TL;DR: This work proposes a novel method for enhancing watershed segmentation by utilizing prior shape and appearance knowledge, which iteratively aligns a shape histogram with the result of an improved k-means clustering algorithm of the watershed segments.
Proceedings ArticleDOI
Approximation with active B-spline curves and surfaces
TL;DR: An active contour model for parametric curve and surface approximation is presented and it is indicated how the latter topic leads to the variational design of smooth motions which interpolate or approximate given positions.

Characterization of the corpus callosum in very preterm and full-term infants utilizing MRI
Deanne K. Thompson,Deanne K. Thompson,Terrie E. Inder,Nathan Faggian,Leigh A. Johnston,Simon K. Warfield,Peter J. Anderson,Lex W. Doyle,Gary F. Egan +8 more
TL;DR: This study characterizes callosal size, shape and diffusion in typically developing infants at term equivalent age, and reports macrostructural and microstructural abnormalities as a result of prematurity.

Automatic segmentation of thoracic and pelvic CT images for radiotherapy planning using implicit anatomic knowledge and organ-specific segmentation strategies.
Benjamin Haas,Thomas Coradi,Martin Scholz,Martin Scholz,Patrik Kunz,M. Huber,U Oppitz,L André,V Lengkeek,Dominique Huyskens,A. Van Esch,R Reddick +11 more
TL;DR: The design, algorithms and validation of new software for the automatic segmentation of CT images used for radiotherapy treatment planning, and the results indicate that the accuracy of the algorithms is within the bandwidth of manual segmentation by experts, except for specific erroneous situations.

Snakes : Active Contour Models
TL;DR: This work uses snakes for interactive interpretation, in which user-imposed constraint forces guide the snake near features of interest, and uses scale-space continuation to enlarge the capture region surrounding a feature.

Active shape models—their training and application
TL;DR: This work describes a method for building models by learning patterns of variability from a training set of correctly annotated images that can be used for image search in an iterative refinement algorithm analogous to that employed by Active Contour Models (Snakes).
