This article talks about computer-based model called "Dialogue Marketing" that interactively tracks and communicates with customers at the exact moments the customer deals with the company, be it during an address change or the purchase of a baby seat. This paper discusses how a company might launch dialogues during customer...
This paper proposes tests to empirically examine whether auction prices aggregate information away from the limit. These tests are based on: A combination of comparative statics with respect to the number of bidders and the dispersion of information signals; and comparison of actual prices to predicted Nash equilibrium prices based...
This paper demonstrates that classical Business Process Reengineering BPR methods can be successfully applied to Computer Aided Surgery while increasing safety and efficiency of the overall procedure through an integrated Workflow Management System. Computer guided Prostate Brachytherapy, as a sophisticated treatment by an interdisciplinary team, is perfectly suited to apply...
The purpose of this paper is to suggest a quantitative method for assessing the temporal changes in the geometry of individual multiple sclerosis MS lesions in follow-up studies of MS patients. The paper concludes that the Quantitative three-dimensional shape analysis can serve as a new tool for monitoring MS lesion...
Establishing image context is the major difficulty of performing laparoscopic ultrasound. The standard techniques used by trans-abdominal ultrasonographers to understand image orientation are difficult to apply with laparoscopic instruments. In this paper, they describe a navigation system that displays the position and orientation of laparoscopic ultrasound images to the operating...
3D freehand ultrasound imaging is becoming a widespread technique in medical examinations. This imaging technique produces a set of irregularly spaced B-scans. Reconstructing a regular grid from these B-scans is a challenging problem that enables the visualization and further analysis of the acquired data. This paper focuses on extending an...
Functional Magnetic Resonance Imaging fMRI studies are derived from a time series of Echo-Planar images EPIs. Compared to conventional Magnetic Resonance Images MRIs, EPIs are of relatively poor quality for discerning anatomic features and are often registered with corresponding MRIs to map brain activity to neuroanatomy. In this paper they...
Magnetic resonance imaging MRI has been used as a research tool in evaluation of the female pelvic floor for over a decade. Early studies were limited because of poor resolution and long scan times, which prohibited evaluation of pelvic floor descent. During the past few years, the advent of surface...
Schizophrenia is a severe mental disorder that affects nearly 1% of the general population and has long been a challenge for both clinicians and researchers in terms of treatment and etiology. More recently, evidence has amassed that suggests that schizophrenia is a brain disorder, and that some aspects of this...
Magnetic resonance diffusion tensor imaging DTI is a new technique that can be used to visualize and measure the diffusion of water in brain tissue; it is particularly useful for evaluating white matter abnormalities. In this paper, they review research studies that have applied DTI for the purpose of understanding...
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...
This paper presents an automated method for colon registration. The method uses dynamic programming to align data defined on colon center-line paths, as extracted from the prone and supine scans. This data may include information such as path length and curvature as well as descriptors of the shape and size...
SCFE is defined as the slippage of the femoral head relative to the femoral neck along the proximal femoral growth plate. The femoral head shifts and rotates along the proximal end of the femoral neck usually posteriorly and inferiorly. Furthermore, a program was developed to simulate different techniques of osteotomies....
This paper describes a new algorithm for nonrigid registration based on an elastically deformable model. The use of registration methods has become an important tool for computer-assisted diagnosis and therapy. Its goal is to improve analysis in various applications of neurology and neurosurgery by improving nonrigid registration. A local gray...
The purpose of this paper was to obtain detailed white matter fiber tract anatomy of the whole brain with a diffusion tensor imaging technique that yields minimal distortion artifacts near large bone structures and air cavities as well as unprecedented high spatial resolution. To attain this goal, they employed line...

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 considers a novel 3D visualization technique based on surface attening for virtual colonoscopy. Such visualization methods could be important in virtual colonoscopy since they have the potential for non-invasively determining the presence of polyps and other pathologies. Further, it demonstrates a method which presents a surface scan of...
This paper discusses about a software tool for pre-operative simulation and planning, and intra-operative guidance, of minimally invasive tumor ablation, including radiofrequency-, laser- and cryo-therapy. This tool provides a pre- and intra-operative optimization of the treatment plan, in order to avoid dangerous probe trajectories, under treatment of the tumor, and...

Powerful computer systems are about to revolutionize several areas of modern medicine. The most famous example is probably neurosurgery, where sophisticated computer algorithms are combined with modern imaging modalities and interventional scanners to enable very reliable surgery in delicate anatomical positions. So far, these high-tech setups are reserved to a...
