Abstract
In a magnetic resonance tomography apparatus and method, whereby an interactive contrast optimization is implemented by defining a multi-contrast sequence for exciting nuclear spins in a slice of a subject to be measured, defining parameters characteristic of the sequence, measuring a number of contrast versions of the slice in the form of raw data with the previously defined sequence, processing the raw data of the slice, and thereby generating a number of images of the slice that differ in contrast from one another and generating an image with improved contrast on the basis of an interactive real-time contrast variation of the images acquired by the multi-contrast sequence, via a user interface.

A method for operating a magnetic resonance tomography apparatus comprising the steps of:
- defining a multi-contrast sequence for exciting nuclear spins in a slice of a subject;
- defining parameters characteristic of said sequence;
- obtaining raw data from said slice by executing said sequence, and from said raw data, generating a plurality of images of said slice having respectively different contrast;
- and
- selectively combining said images with respectively different contrast in an interactive, real-time contrast variation via a user interface to generate an image with an optimum contrast.
A magnetic resonance tomography apparatus comprising:
- a system computer wherein a multi-contrast sequence for exciting nuclear spins in a slice of a subject is defined, and wherein parameters characteristic of said sequence are defined;
- a magnetic resonance scanner operated by said system computer to execute said multi-contrast sequence to obtain raw data of said slice;
- said system computer processing said raw data to generate a plurality of images of said slice with respectively different contrast;
- and
- a user interface connected to said system computer at which said plurality of images are displayed, and having a user actuatable input allowing said plurality of images to be selectively combined in real-time interactive contrast variation to generate a contrast-optimized image from said plurality of images.
A computer program product loadable into a computer of a magnetic resonance tomography apparatus for operating said computer for defining a multi-contrast sequence for exciting nuclear spins in a slice of a subject, defining parameters characteristic of said sequence, obtaining raw data from said slice by executing said sequence, and from said raw data, generating a plurality of images of said slice having respectively different contrast;
- and selectively combining said images with respectively different contrast in an interactive, real-time contrast variation via a user interface to generate an image with an optimum contrast.
