Magnetic resonance imaging (MRI) as a non invasive medical diagnostic technology which has been widely used in clinical medical diagnosis. Its imaging quality requires extremely high homogeneity of the main magnet. In this paper, focused on the passive shimming technology for superconducting MRI systems, we proposed a rapid spherical harmonic coefficient calculation method based on completely associated legendre functions. This paper continued to analyzed the influence of the distribution density of shimming pieces on the passive shimming by change the size and space of shimming pieces, in order to achieve the magnetic field homogeneity requirements with lower costs. The conclusions have reference significance.

Recent advancements in magnetic resonance imaging (MRI) techniques are promising for the detection of fetal abnormalities, and MRI may supplement or replace prenatal ultrasound scans in the future. In particular, the interest of scientific and medical communities in high-field (3T) MRI continues to grow due to its improved contrast-to-noise and signal-to-noise ratios compared to clinical MRI of lower field strength (1.5T).

Passive shimming is widely used in magnetic resonance imaging (MRI) systems due to its excellent efficacy and cost-effectiveness. However, conventional shim tray structures have difficulty in effectively adjusting magnetic field distributions under specific conditions. This limitation can lead to insufficient cancellation of harmonics and result in significant residual forces on the trays, impeding accurate placement of the trays.

Purpose: To improve transmit B field homogeneity and longitudinal coverage of a human head RF array, we developed a novel eight-element transceiver (TxRx) array using composite elements based on paired folded-end dipoles.
Methods: The developed array consisted of eight pairs of coupled folded-end dipoles. Only one dipole in each pair was driven during transmission, while the other was passively coupled with the active one.
