Abstract
In an image reconstruction method and device for a magnetic resonance imaging system, a magnetic resonance scan is performed at least one scan position according to at least one scan protocol, to acquire at least a set of one scan protocol simultaneously acquired data. At least one magnetic resonance image is reconstructed based on the set of scan protocol simultaneously acquired data and a shared receiving coil calibration matrix. By sharing the receiving coil calibration matrix in different parallel scan processing operations, the amount of work is significantly reduced while improving working efficiency, and imaging quality can also be significantly improved in the case of scan sequences with echo chain acquisition.
Claims10
A magnetic resonance (MR) reconstruction method, comprising:
- from a control computer, operating an MR scanner, comprising multiple receiving coils, to perform multiple MR scans of an examination subject, situated in said MR scanner, respectively at multiple scan positions, each MR scan being performed according to at least one scan protocol;
- in each of said multiple MR scans, operating said MR scanner from said control computer to acquire MR data from the subject simultaneously with the respective multiple reception coils, thereby acquiring a set of scan protocol simultaneously acquired data;
- providing the respective sets of scan protocol simultaneously acquired data, respectively acquired in each of said multiple scans, to an image reconstruction computer and in said image reconstruction computer, reconstructing at least one MR image of the subject from at least one of said sets of scan protocol simultaneously acquired data, using a shared receiving coil calibration matrix that is shared among at least two of said sets of scan protocol simultaneously acquired data;
- and
- making the reconstructed MR image available in electronic form at an output of said image reconstruction computer as a data file.
An image reconstruction device for a magnetic resonance (MR) scanner, comprising:
