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 Stimulation (TMS).

Traumatic Brain Injury l: Introduction

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

To address the challenges of visualizing spatiotemporal and topological patterns in brain data.

Main Methods:

DTBIA developed in collaboration with domain experts, incorporating a hierarchical workflow (brain regions to voxels).
Utilizes immersive navigation and a 3D edge bundling algorithm for enhanced clarity.
Analyzes both functional (BOLD) and structural (DTI) brain data.

Main Results:

DTBIA provides multi-level detail visualization of complex neural data.
The system enhances clarity and offers deeper insights into brain data.
Validated through case studies with brain research experts.

Conclusions:

DTBIA effectively addresses the visualization challenges of Digital Twin Brain data.
