AI Technical Summary
Technical Problem
Existing antennas for MRI require significant space, leading to high mutual coupling, reduced efficiency, and limited resolution due to electromagnetic interactions, which affects the homogeneity and signal-to-noise ratio of imaging techniques.
Method used
An antenna design incorporating a radiating section and a feeding section with capacitance and inductance, allowing for a compact arrangement that minimizes coupling, enabling a high number of antennas per area/volume, improving B1 field uniformity and signal-to-noise ratio.
Benefits of technology
The compact antenna design enhances imaging quality by increasing the number of channels, improving B1 field homogeneity, and boosting signal-to-noise ratio, while being cost-effective and technically simple to construct.

Abstract
The invention relates to an antenna and an antenna assembly for an imaging method, to a method for adjusting the length of an antenna and to a tomography system, in particular for magnetic resonance tomography (MRT) or simultaneous positron emission tomography and MRT (PET-MRT). An antenna (1) for an imaging method comprises a radiation section (2) and a feed section (3). The feed section (3) comprises a capacitor (11) and an inductor (15).
