3D turbo spin echo sequences (e.g. SPACE) suffer from
long acquisition times and are therefore prone to motion
artifacts. Two features are introduced into SPACE
imaging: a) integrated motion detection, which judges
whether a patients movement is tolerable or not, and
stops the acquisition immediately when unacceptable
motion is detected; b) a dedicated sampling strategy,
which optimizes the image quality in cases that an
acquisition is interrupted. Comprehensive in vivo
experiments have been conducted to evaluate the
performance of the method.
