Functional MR Imaging of a Predetermined Volume Section of the Brain of a Living Subject

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and system for functional magnetic resonance (MR) imaging of a specific region of the brain in a living subject. The technique involves using a radiofrequency (RF) excitation pulse and controlled magnetic gradients to capture MR data from the targeted brain region, with data acquisition starting at a very short, precise echo time (between 10 and 1000 microseconds) after the RF pulse.

Use CasesContent extracted from patent full text and abstract with AI.

• Advanced brain research to study localized neural activity.
• Clinical diagnosis of neurological disorders using functional MR imaging.
• Real-time monitoring of brain function during surgery or treatment.
• Improved imaging protocols in neuroscience to observe specific brain regions.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables high-resolution, targeted imaging of small brain areas.
• Reduces the time needed to acquire MR data from specific regions, increasing efficiency.
• Potentially improves the accuracy and detail of functional brain scans for diagnostics and research.
• Minimizes interference from signals outside the region of interest, leading to clearer images.

Patent Abstract

In a method and a magnetic resonance (MR) system for functional MR imaging of a predetermined volume segment of THE brain of a living examination subject, an RF excitation pulse is radiated into the subject and at least one magnetic field gradient is activated, and MR data of the predetermined volume segment is acquired beginning at a predetermined echo time after the RF excitation pulse. The echo time is in a time period of 10 mus to 1000 mus.
