| Popis: | The total time spent on each patient during an MR study determines patient throughput and ultimately influences MR scan charges. Actual data acquisition often represents only a small portion of this examination time. Other functions such as patient loading and unloading, positioning, coil placement, scan setup, and image reconstruction time also contribute to the total examination time. We describe a technique for creating automated imaging protocols for standard MR examinations which optimize these functions, thereby decreasing operator interventions and shortening the overall examination time. A prototype sequence for examining the larynx and neck was developed which allowed three sequential multiple slice acquisitions to be obtained in three orthogonal planes with a single operator setup step. All tuning and scan placement after this first step was done under computer control. The new sequence allowed larynx and neck studies to be performed in less than 30 min for spin echo and under 16 min for field echo instead of the 50–60 min required by previous methods. The new technique should be useful for improving patient throughput for a cariety of standardized examinations including the temporal bone, head and neck, joints, and other regions. |
