In the simplest form of SE imaging, the pulse sequence has to be repeated as many times as the image has lines.Contrast values: PD weighted: Short TE (20 ms) and long TR. T1 weighted: Short TE (10-20 ms) and short TR (300-600 ms) T2 weighted: Long TE (greater than 60 ms) ...
These tests are completed in a fixed order on assessment day 1. Emotion Regulation Questionnaire (ERQ): To measure inter-individual differences in habitual emotion regulation, participants completed the German version35 of the emotion regulation questionnaire (ERQ)36, which has 10 items that are ...

Furthermore, the size of the segmentation objects in the uncompressed form is smaller than that of the segmented image series, limiting the practical need for compression. We note that there are small numeric discrepancies (on the order of 0.001, in our case) in the ImagePositionPatient between...

Returning to FIG. 1, the longitudinal member16is preferably telescoping, in order to control another characteristic of the slice image, such as the depth of the slice image. The longitudinal member16may comprise a first, lower longitudinal member22with the first end17connected to the base12, as...
