Scheme of retrospective breathing-gated image reconstruction. (a) Having the knowledge of the motion function z(t), here modeled for simplicity as a sinusoidal function, it is possible to set a specific time gating window TGW triggered on a particular phase of the motion. (b) By collecting several images (I1, I2, I3, …), and selecting the corresponding “patches” we can reconstruct an image where each point has the same height within in the imaged volume. (c) A reconstructed motion-free image obtained starting from raw images, using the retrospective breathing-gated image reconstruction technique. Reprinted with permission from [13]. © 2012 SPIE.
