摘要： A screen apparatus includes a screen assembly and structure. The structure defines a cavity having an opening to a vehicle passenger compartment. The screen assembly includes a frame and a video screen mounted with respect to the frame. The screen assembly is selectively movable between a retracted position in which the screen is inside the cavity and concealed from view, and a deployed position in which the screen is outside the cavity and visible from the passenger compartment. The screen apparatus is configured such that the movement of the screen assembly between the retracted and deployed positions is restricted to substantially linear translation.

摘要： At least one imaging parameter (e.g., the repetition interval TR or the initial nutation angle .theta.) is varied during the course of a single MR image sequence. This variation in at least one imaging parameter is preferably controlled so as to increase the contrast and signal-to-noise ratio of lower spatial frequency image components. For example, by using longer TR intervals (or smaller initial nutation angle .theta.) during lower spatial frequency phase encoding sub-sequences, relatively more signal is gathered from NMR nuclei having long T1 parameters thus providing a resultant image with many characteristics of a much longer overall sequence (e.g., one using uniform relatively long TR intervals for all spatial frequency phase encoding sub-sequences).
摘要翻译：在单个MR图像序列的过程中，至少一个成像参数（例如，重复间隔TR或初始章动角θ）是变化的。优选地控制至少一个成像参数中的这种变化，以便增加较低空间频率图像分量的对比度和信噪比。例如，通过在低空间频率相位编码子序列期间使用较长的TR间隔（或较小的初始章动角θ），从具有长T1参数的NMR核收集相对较多的信号，从而提供具有更长时间的许多特征的合成图像整个序列（例如，对于所有空间频率相位编码子序列使用统一的相对长的TR间隔的一个序列）。
