Jan 10, 2018 · To figure out what a person is seeing, researchers turned to functional magnetic resonance imaging (fMRI), which measures blood flow to the brain as a proxy for neural activity. They mapped out visual processing areas to a resolution of 2 millimeters as three people looked at more than 1000 images several times each. Overview What is functional MRI? Functional magnetic resonance imaging (fMRI) is an imaging scan that shows activity in specific areas of the brain. In medical settings, fMRI mainly helps plan brain surgeries and similar procedures.Multiple sclerosis. Spinal cord conditions. Stroke. Tumors. Brain injury from trauma. A special type of MRI is the functional MRI of the brain, also known as fMRI. It produces images of blood flow to certain areas of the brain. The DICOM file contains a header (that stores patient's name, age, sex, type of scan, image dimensions, etc) as well as all of the image data (that can contain information in three dimensions). The current DICOM standard is widely accepted among major vendors, and for storing and transferring relatively simple image data works very efficiently.

The fMRI scanner create images of areas that are responsible for movement, language, memory and other functions. The test identifies these regions by detecting changes in blood flow and oxygen levels as you answer questions and perform simple tasks. For example, the technician may ask you to tap your thumb against each finger on the same hand.

In an upcoming juvenile-sex-abuse case in San Diego, the defense is hoping to get an fMRI scan, which shows brain activity based on oxygen levels, admitted to prove the abuse didn't happen.The temporal dimension of fMRI data.
