This paper describes a novel algorithm for altering global intensity statistics of magnetic resonance images MRI to fit a model distribution while preserving local feature contrast. The algorithm estimates a multiplicative correction field that alters the intensity statistics of an image or set of images to best match those of...
Three-dimensional visualization with virtual endoscopy of the bladder appears to be a promising tool for screening and follow up of cancer. Vining reported a sensitivity of only 23% in detecting tumors smaller then 5mm using virtual cystoscopy. To improve identification of these lesions we developed an algorithm for color mapping...
Medical images are brought into spatial correspondence, or aligned, by the use of registration algorithms. Nonrigid registration refers to the set of techniques that allow the alignment of datasets that are mismatched in a nonrigid or non-uniform manner. Such misalignments can result from physical deformation processes, or can be a...
Characterizing the performance of image segmentation approaches has been a persistent challenge. Performance analysis is important since segmentation algorithms often have limited accuracy and precision. Interactive drawing of the desired segmentation by domain experts has often been the only acceptable approach, and yet suffers from intra-expert and inter-expert variability. Automated...
The paper introduces an algorithm which allows the automatic segmentation of multi channel magnetic resonance images MRI. They extended the Expectation Maximization-Mean Field Approximation (EM-MF) Segmenter, to include Local Prior Probability Maps. Thereby their algorithm estimates the bias field in the image while simultaneously assigning voxels to different tissue classes...
Assessment of normal and abnormal anatomical variability requires a coordinate system enabling inter-subject comparison. This paper presents a binary minimum entropy criterion to assess affine and nonrigid transformations bringing a group of subject scans into alignment. This measure is a data-driven measure allowing the identification of an intrinsic coordinate system...
This paper describes about a new algorithm for nonrigid registration of brain images based on an elastically deformable model. The use of registration methods has become an important tool for computer-assisted diagnosis and surgery. The goal of this paper was to improve analysis in various applications of neurology and neurosurgery...
This paper discusses about the goal to improve image guidance during minimally invasive image guided therapy by developing an intraoperative segmentation and nonrigid registration algorithm. The algorithm was designed to allow for improved navigation and quantitative monitoring of treatment progress in order to reduce the time required in the operating...
This paper provides a generic algorithm for the segmentation of three dimensional multi-spectral magnetic resonance images. The algorithm is unsupervised and adaptive, does not require initialization, classifies the data in any number of tissue classes and suggests an optimal number of classes. It uses a statistical model including Bayesian distributions...
