Fully Automatic Segmentation of Head and Neck Organs using Active Appearance Models
No opinion
We present a fully automatic model based system for segmenting the mandible, parotid and submandibular glands, brainstem, optic nerves and the optic chiasm in CT images, which won the MICCAI 2015 Head and Neck Auto Segmentation Grand Challenge. The method is [...]

A Treatment Planning System for the Small Animal Radiation Research Platform (SARRP) based on 3D Slicer
starstarstarstarstar
This paper describes the software integration of a treatment planning system (TPS), based on the open-source 3D Slicer package, with the Small Animal Radiation Research Platform (SARRP).The TPS is designed to enable researchers to replicate their clinical [...]

Head and Neck Auto-segmentation Challenge
No opinion
This paper presents the results of the Head and Neck Auto-segmentationChallenge, which was part of the workshop “3D Segmentation in the Clinic: A Grand Challenge”. This workshop took place in London, UK, in September 2009, in conjunction with the 12th [...]

Exporting Contours to DICOM-RT Structure Set
starstarstarstarstar
This paper presents an ITK implementation for exporting the contours of the automated segmentation results to DICOM-RT Structure Set format. The “radiotherapy structure set” (RTSTRUCT) object of the DICOM standard is used for the transfer of patient [...]

VV: a viewer for the evaluation of 4D image registration
starstarstarstarstar
We propose an open source and cross platform medical image viewer, named VV, designed for qualita tive evaluation of images registration, in particular for deformable registration of 4D CT images. VV can display multiple spatio-temporal image sequences (2D+t [...]

Importing Contours from DICOM-RT Structure Sets
starstarstarstarstar
This paper presents parsing software for importing contours from DICOM RT structure set files into binary image files. This is a common requirement for transferring expert manual segmentations from radiotherapy treatment planning software into external image [...]

Multimodal Analysis of Vasogenic Edema in Glioblastoma Patients for Radiotherapy Planning
No opinion
Glioblastoma (GBM) is the most common type of primary brain tumor, which is characterized by an infiltrative growth pattern. In current practice, radiotherapy planning is primarily based upon T2 FLAIR MRI despite its known lack of specificity in the detection [...]

Dose Painting with a Variable Collimator for the Small Animal Radiation Research Platform (SARRP)
No opinion
The goal of radiation treatment is to irradiate cancer cells (i.e., a target region) without destroying adjacent healthy tissue. Thus, it is advantageous to form the beam so that it best approximates the target, thereby reducing the amount of dose absorbed in [...]

A Multi-atlas Approach for the Automatic Segmentation of Multiple Structures in Head and Neck CT Images
No opinion
A multi-atlas approach is proposed for the automatic segmentation of nine different structures in a set of head and neck CT images for radiotherapy. The approach takes advantage of a training dataset of 25 images to build average head and neck atlases of [...]

ITK-Based Implementation of Two-Projection 2D/3D Registration Method with an Application in Patient Setup for External Beam Radiotherapy
starstarstarstarstar
This document describes an ITK-based implementation of intensity-based 2D/3D rigid image registration for patient setup assessment in external beam radiotherapy. The registration framework was designed to simultaneously register two projection images to a 3D [...]

Automatic Segmentation of Head and Neck CT Images by GPU-Accelerated Multi-atlas Fusion
No opinion
Treatment planning for high precision radiotherapy of head and neck (H&N) cancer patients requires accurate delineation of critical structures. Manual contouring is tedious and often suffers from large inter- and intra-rater variability. In this paper, we [...]

Active Contour-Based Segmentation of Head and Neck with Adaptive Atlas Selection
No opinion
This paper presents automated segmentation of structures in the Head and Neck (H&N) region, using an active contour-based joint registration and segmentation model. A new atlas selection strategy is also used. Segmentation is performed based on the dense [...]

Multi Atlas Segmentation with Active Shape Model Refinement for Multi-Organ Segmentation in Head and Neck Cancer Radiotherapy Planning
No opinion
We describe a segmentation method that was used in the Head and Neck Auto Segmentation Challenge held at the MICCAI 2015 conference. The algorithm consists of two building blocks. First, we employ a multi-atlas segmentation to obtain an initial segmentation [...]
