Download, This paper presents a novel retrospective gating method for 4d (dynamic 3d) mr imaging during free breathing to capture the full variability of respiratory organ deformation. This method was designed to acquire a time series of volumetric 3d images of a cyclically moving organ, enabling therapy to be guided by synchronizing the 4d image with the actual organ motion in real time. For real‐time 3d visualization of respiratory organ motion for mri‐guided therapy, a new adaptive 4d mr imaging method based on navigator echo and multiple gating windows was developed. This paper describes a method for 4d imaging, which is used to study respiratory organ motion, a key problem in various treatments.

The proposed method was developed to study irregularities in organ motion during free breathing over tens of minutes, which does not assume a constant breathing depth or even strict periodicity and does not depend on an external respiratory signal. Other gating methods assume regular respiratory motion and reduce the respiratory organ deformation to one parameter such as amplitude or phase..
