Abstract

A novel setup for whole‐body MR imaging with moving table continuous data acquisition has been developed and evaluated. The setup features a manually positioned moving table platform with integrated phased‐array surface radiofrequency coils. A high‐precision laser position sensor was integrated into the system to provide real‐time positional data that were used to compensate for nonlinear manual table translation. This setup enables continuous 2D and 3D whole‐body data acquisition during table movement with surface coil image quality. The concept has been successfully evaluated with whole‐body steady‐state free precession (TrueFISP) anatomic imaging in five healthy volunteers. Seamless coronal and sagittal slices of continually acquired whole‐body data during table movement were accurately reconstructed. The proposed strategy is potentially useful for a variety of applications, including whole‐body metastasis screening, whole‐body MR angiography, large field‐of‐view imaging in short bore systems, and for moving table applications during MR‐guided interventions.
