Embodiment Construction

[0026] figure 1 An overall view of a set of magnetic resonance imaging systems 100 is depicted. The system 100 includes a magnetic resonance scanner 101 . The magnetic resonance scanner is operative to generate magnetic resonance imaging data by scanning a living object. The magnetic resonance scanner is further connected to a computer 103 for processing data generated by the scanner 101 . The computer includes a central processing unit connected to a memory and a plurality of input and output ports for receiving and outputting data and information. The computer 103 receives input commands from one or several input devices, typically represented by the input device 105 . The input devices may be one or more computer mice, keyboards, trackballs, or any other input devices. The computer 103 is further connected to a display 107 for displaying the processed scan data as a contrast image. In particular, said computer 103 may comprise a controller unit / imaging circuit arranged...

Abstract

A computerized method of generating a map of myelin tissue of a brain is described. In addition sub-maps of different myelin contents can be imaged. The method uses a simulation model comprising at least two interacting tissue compartments.

Description

technical field [0001] The present invention relates to methods, systems and computer program products for generating images of portions of brain tissue obtained from magnetic resonance quantification sequences. In particular, the present invention also provides methods, systems and computer program products for generating partial images of brain myelin based on a plurality of physical parameters. Background technique [0002] Magnetic resonance imaging (MRI) can produce cross-sectional images in any plane, including oblique planes. Medical magnetic resonance imaging most often relies on the relaxation of active hydrogen nuclei (protons) in water and fat. When the imaged object is placed in a strong and uniform magnetic field, the spins of the nuclei with non-integer spin numbers in the tissue are either all aligned parallel to the magnetic field, or all aligned antiparallel to the magnetic field. The output of the magnetic resonance imaging scan is an magnetic resonance i...
