First Claim
Patent Images
1. A method for recording magnetic resonance (MR) data, comprising:
- using a control computer to operate an MR data acquisition scanner to acquire MR data by executing multiple repetitions of a bSSFP sequence;
using said control computer to enter the acquired MR data into an electronic memory organized as k-space comprising a plurality of k-space lines in said electronic memory, by dividing a k-space line, into which said acquired MR data are to be entered, into at least two line sections, and entering the acquired MR data respectively into at least two of said at least two line sections separately in different repetitions of said bSSFP sequence; and
from said control computer, making the data entered into k-space available in electronic form, as a data file.

Abstract
In a method and magnetic resonance apparatus for recording magnetic resonance data using a bSSFP sequence, a k-space line to be scanned in k-space is divided into at least two line sections, with at least two of the at least two line sections being scanned separately in different repetitions of the sequence.

8. A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a control computer of a magnetic resonance (MR) apparatus comprising an MR data acquisition scanner and an electronic memory, said programming instructions causing said control computer to:
-
operate the MR data acquisition scanner to acquire MR data by executing multiple repetitions of a bSSFP sequence; enter the acquired MR data into the electronic memory, organized as k-space comprising a plurality of k-space lines in said electronic memory, by dividing a k-space line, into which said acquired MR data are to be entered, into at least two line sections, and entering the acquired MR data respectively into at least two of said at least two line sections separately in different repetitions of said bSSFP sequence; and make the data entered into k-space available in electronic form, as a data file.
