Method and apparatus for functional magnetic resonance imaging
First Claim
Patent Images
1. A method for operating a magnetic resonance apparatus for functional imaging, comprising the steps of:
- obtaining a plurality of images, each comprised of picture elements, of a subject in a sequence and alternatingly obtaining the plurality of images within said sequence with stimulation of said subject and without stimulation of said subject; and
storing each image in said plurality of images together with information independent of said picture elements indicating whether that image was registered with or without stimulation of said subject and together with at least one image-related stimulation value that is independent of said picture elements, and together with at least one image-related evaluation correlation value that is independent of said picture elements, said correlation value comprising a point on a time-related correlation curve coinciding with a point in time of the acquisition of the image stored with the image-related evaluation correlation value.

Abstract
In a method and a magnetic resonance apparatus for functional imaging, a number of images without and with a designational stimulation of the examination subject are sequentially registered in successive alternation, and an information value that indicates whether the image was registered during a phase with or without stimulation, at least one image-related stimulation value, and at least one image-related evaluation correlation value are obtained and stored for every image.

5. A magnetic resonance apparatus for functional imaging, comprising:
-
a magnetic resonance scanner with a sensory stimulator obtaining a plurality of images, each comprised of picture elements, of a subject in a sequence and alternatingly obtaining the plurality of images within said sequence with sensory stimulation of said subject and without sensory stimulation of said subject; and a memory storing each image in said plurality of images together with information. independent of said picture elements indicating whether that image was registered with or without stimulation of said subject and together with at least one image-related stimulation value, that is independent of said picture elements and together with at least one image-related evaluation correlation value that is independent of said picture elements, said correlation value comprising a point on a time-related correlation curve coinciding with a point in time of the acquisition of the image stored with the image-related correlation value. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
