Abstract
The present invention relates to a magnetic resonance tomography apparatus for generating tomography data of an examination object in a magnetic field by means of an electromagnetic pulse sequence, having a memory for storing reference tomography data of a reference examination object; an acquisition facility for generating tomography data of the reference examination object by means of the pulse sequence; and an adjustment facility for reducing a deviation between the tomography data and the reference tomography data by adjusting a physical parameter in the pulse sequence.
Claims15
A magnetic resonance tomography apparatus comprising:
- an electronic memory in which reference tomography data of a reference object are stored;
- a magnetic resonance scanner;
- a control computer configured to operate the magnetic resonance scanner, while an examination object is situated in the magnetic resonance scanner, to acquire magnetic resonance tomography data from the examination object by executing a data acquisition pulse sequence with the magnetic resonance scanner;
- and
- an adjustment computer having access to said memory, and provided with said magnetic resonance tomography data acquired from the examination object, said adjustment computer being configured to reduce a deviation between said magnetic resonance tomography data acquired from the examination object and the reference tomography data by adjusting a physical parameter of said pulse sequence, and thereby making an adjusted pulse sequence available to said control computer in an electronic form for operating said magnetic resonance scanner.
A method for producing a pulse sequence for operating a magnetic resonance tomography apparatus, said method comprising:
- storing reference tomography data of a reference object are stored in an electronic memory;
- from a control computer, operating a magnetic resonance scanner, while an examination object is situated in the magnetic resonance scanner, to acquire magnetic resonance tomography data from the examination object by executing a data acquisition pulse sequence with the magnetic resonance scanner;
- and
- providing an adjustment computer with said magnetic resonance tomography data acquired from the examination object and, from said adjustment computer, accessing said memory to obtain said reference tomography data, and in said adjustment computer, reducing a deviation between said tomography data acquired from the examination object and the reference tomography data by adjusting a physical parameter of said data acquisition pulse sequence, and thereby making an adjusted data acquisition pulse sequence available to said control computer in an electronic form for operating said magnetic resonance scanner.
