| Zusammenfassung | Dipole antennas can be considered as an alternative for transmit-receive coil arrays tailored for ultra-high field MRI. Dipole antenna configurations offer improvements in signal-to-noise-ratio (SNR) and B1+ efficiency versus loop element or strip element configurations. The traits of radiative elements are also useful for radio frequency (RF) hyperthermia which is of proven clinical value as an adjunctive therapy for established cancer treatments like radiotherapy and chemotherapy. Realizing these opportunities this work proposes a bow-tie dipole antenna building block and examines its capabilities for MR imaging and its properties for RF-heating at 297MHz in an attempt to explore the feasibility of an multi-channel hybrid hyperthermia-imaging coil configuration for ultra-high fields (7.0 T). To meet these goals numerical field simulations were performed to analyze the imaging and heating properties. Validation experiments were carried out in phantoms. |
