Automated shimming improves image quality and reduces frequency offsets in lung imaging, indicating potential clinical benefits.

To develop and validate a rapid method for shimming the lung using a fully automated approach.
Used a custom 2D RF spoiled gradient echo sequence for field mapping of the lung.
Acquired four echo‐shifted coronal images at 3T with a minimum TE of 0.57 ms and inter‐echo spacing of 0.1 ms.
Performed imaging in free‐breathing mode with three repetitions totaling 4.2 s scan time.
Shimming of the lung was successfully achieved in all volunteers in under 10 seconds.
Subject-specific shimming reduced mean frequency offset in the lung by up to 45 Hz.
Improved bSSFP signal homogeneity led to more uniform functional images, enhancing image quality.
