Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

Neuroimaging
Medical Image Analysis
Computational Anatomy

Background:

Advances in medical imaging (MR/CT, PET/SPECT) provide 3D brain data.
Current anatomical atlases are rigid, based on single subjects.
Multi-modality image registration is crucial for correlated analysis.

Purpose of the Study:

To develop a computerized anatomical atlas with probabilistic spatial distributions.
To improve diagnosis, disease pathology study, and brain surgery planning.
To enable model-based segmentation and labeling of MR brain images.

Main Methods:

Review of knowledge-based segmentation, labeling, and MR brain image analysis.
Principal Axes Transformation for registration of 3D MR brain images.
Development of composite models for internal brain structures.

Main Results:

Creation of a computerized anatomical atlas with probabilistic distributions.
Demonstration of composite models for atlas-based segmentation and labeling.
Successful registration and correlation of MR and PET images for metabolic analysis.

Conclusions:

The proposed atlas overcomes limitations of conventional atlases by incorporating variability.
The methodology facilitates improved diagnostic accuracy and personalized treatment planning.
This approach enhances the understanding of brain structure-metabolism relationships.
