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:

Neuroscience
Computer Science
Data Visualization

Background:

Visualizations of sensitive biomedical data, like neuroimaging, risk exposing personal information.
Differential privacy offers a robust framework for protecting individual data privacy.

Purpose of the Study:

To investigate privacy-preserving visualization techniques for neuroimaging data using differential privacy.
To develop and evaluate methods that balance privacy guarantees with visual utility.

Main Methods:

Applied differential privacy by perturbing correlation values in neuroimaging data.
Developed specific workflows for connectogram and seed-based connectivity visualizations.
Analyzed privacy cost and the effects of pre- and post-processing steps.

Main Results:

Proposed workflows successfully generated visualizations comparable to non-private versions.
Qualitative assessments of visualizations were preserved under differential privacy.
Demonstrated a viable privacy/visual utility tradeoff for neuroimaging data.

Conclusions:

Differential privacy is a promising approach for securing sensitive information in biomedical data visualizations.
The developed methods effectively protect privacy without significantly compromising visual interpretability.
