Abstract

Systems and methods for obtaining anatomical-structure-specific activation data in a brain of a patient are provided. In an embodiment, a method for obtaining anatomical-structure-specific activationdata in a brain of a patient includes receiving magnetic resonance (MR) data of the brain obtained by use of a magnetic resonance imaging (MRI) device; segmenting the MR data of the brain to delineatea plurality of geometries, each of the plurality of geometries corresponding to a respective anatomical structure in the brain; receiving functional magnetic resonance (fMRI) data of the brain obtained by use of an MRI device; aligning the MR data and the fMRI data; determining a plurality of activation levels, each of the activation levels corresponding to respective delineated geometries basedon the aligned MR data and fMRI data; and outputting a graphical representation of a dynamic activity in the brain corresponding to the delineated geometries of the anatomical structures.

Description

technical field [0001] The present disclosure relates generally to functional magnetic resonance imaging, and in particular to devices, systems and methods for anatomy-specific functional magnetic resonance imaging. Background technique [0002] Functional magnetic resonance imaging (fMRI) is a variant of magnetic resonance imaging (MRI). fMRI relies on the fact that oxygenated and deoxygenated hemoglobin have different magnetic properties, resulting in different magnetic resonance (MR) signal intensities. Because cerebral blood flow is directly related to neuronal activation, by measuring blood demand in a brain region, fMRI can measure the activation level of that brain region. During fMRI scans, patients are given tasks designed to increase regional brain activity, and the MRI equipment is able to detect changes in the ratio of oxygenated to deoxygenated blood. Changes in the ratio of oxygenated blood to deoxygenated blood can be used for a task-related time series of m...
