Real-time imaging

Definition

Real-time imaging refers to the ability to capture and display images of the brain or other biological structures as they happen, allowing researchers and clinicians to monitor changes dynamically. This technique is crucial in neuroimaging as it enables the observation of brain activity during various cognitive tasks, providing insights into how different areas of the brain respond in real time. The immediacy of this imaging allows for a deeper understanding of neurological processes and potential abnormalities.
