We propose a two-dimensional cylindrical high-pass ladder (2D c-HPL) coil concept and investigate the contribution of the longitudinal dimension to utilize a bore-mounted general-purpose clinical volume coil for ultra-high field MRI. Theory and in-silico results show that this architecture exhibits improved B1 field uniformity for specific anatomies and regions such as brain (a coefficient of variation of 12.3%), cerebellum (4.9%), heart (16.7%), prostate (2.8%), and whole chest (36.8%). This could prove particularly useful for whole-body clinical imaging and could open new pathways for clinical diagnostics in UHF MRI.
