PET radiotracer imaging with the labeled glucose analogue [18F]-fluorodeoxyglucose (FDG)
is increasingly being used in oncology imaging because of its usefulness in detecting and …

To stimulate the advancement of computer-aided diagnostic (CAD) research for lung
nodules in thoracic computed tomography (CT), the National Cancer Institute launched a …

We propose a method for brain atlas deformation in the presence of large space-occupying
tumors, based on an a priori model of lesion growth that assumes radial expansion of the …

We present software for integrated analysis of brain PET studies and coregistered
segmented MRI that couples a module for automated placement of regions of interest (ROI) …

The discovery of the X ray by Roentgen in 1895 provided a method to visualize anatomic
structures in a living body. This event was one of the most striking episodes in the history of …

In recent years, mutual information has proved to be an excellent criterion for registration of
intra-individual images from different modalities. Multi-resolution coarse-to-fine optimization …

Voxel-based nonrigid image registration can be formulated as an optimisation problem
whose goal is to minimise a cost function, consisting of a first term that characterises the …

Software image registration is a powerful and versatile tool that allows the fusion of
molecular and anatomic information. Image registration can be applied to compare anatomic …

Differential diagnosis of pancreatic lesions still remains a problem. Whereas CT provides
high spatial resolution, PET detects malignant lesions with high sensitivity. The objective of …

A measure for registration of medical images that currently draws much attention is mutual
information. The measure originates from information theory, but has been shown to be …
