View Sharing in slice direction for continuously moving table acquisitions: Application to TOF venography

Introduction To increase the temporal resolution in time-resolved MRI, several view sharing (VS) techniques have been developed. Typically, high spatial frequencies are not fully sampled for all time frames and data from the different time frames are combined to generate full k-space data [1, 2]. In this study the VS concept was applied to share data between different slice positions for axial continuously moving table (CMT) acquisitions. The kspace was divided into three segments for each slice and k-space data was shared for different slice positions. By the variation of the patient table velocity the degree of VS could be flexibly adjusted. The feasibility of CMT VS was tested on healthy volunteers for the application to CMT Timeof-Flight (TOF) venography of the peripheral vessels [3].
