Title:
【発明の名称】核磁気共鳴断層撮影装置
Document Type and Number:
Japanese Patent JP2904858
Kind Code:
B2
Abstract:
The invention relates to a nuclear-spin tomograph having a high-frequency antenna, the inner conductor of which together with at least one shortening capacitance form a waveguide resonator. According to the invention, a waveguide resonator is provided for several resonator frequencies (f1, f2) and rejection circuits (50 to 53) are provided for decoupling the inner conductors (4 and 6). In this embodiment, the nuclear-spin tomograph can be used for several resonant frequencies of, for example, f1 = 170 MHz for protons (hydrogen) and f2 = 69 MHz for phosphorus.
