Abstract
For the purpose of suppressing degradation in visibility of an image by a missing line due to the subject motion, the step of selectively exciting a linear region with intersecting 90° and 180° pulses and applying an MPG pulse to collect data is repeated with the linear region shifted; whether the acquired data for each line is affected by the subject motion is detected; and if the data is affected by the subject motion, interpolated data is employed in place of the data.
Claims16
An MR imaging method for reconstructing an MR image using a pulse sequence according to an LSDI technique in which the step of selectively exciting a linear region and applying an MPG pulse to collect data is repeated, said method comprising:
- detecting data affected by the subject motion;
- and re-imaging a region corresponding to said data.
An MR imaging method for reconstructing an MR image using a pulse sequence according to an LSDI technique in which the step of selectively exciting a linear region and applying an MPG pulse to collect data is repeated, said method comprising:
- detecting data affected by the subject motion;
- and employing interpolated data in place of said data.
An MRI apparatus comprising:
- RF pulse transmitting means for transmitting an RF pulse;
- gradient magnetic field applying means for applying a gradient magnetic field;
- data collecting means for collecting data;
- pulse sequence control means for executing a pulse sequence according to an LSDI technique in which the step of selectively exciting a linear region and applying an MPG pulse to collect data is repeated;
- and re-imaging control means for detecting data affected by the subject motion, and re-imaging a region corresponding to said data.
