The purpose of this work was to assess the reproducibility of percentage of ventilated lung volume (PV) measured from hyperpolarized (HP) 3He and 1H anatomical images acquired in the same breath‐hold when compared with PV measured from 3He and 1H images from separate breath‐holds.
Volumetric 3He ventilation and 1H anatomical images of the same resolution were acquired during the same breath‐hold....
Adding prior knowledge to compressed sensing reconstruction can improve image reconstruction. In this work, two approaches are investigated to improve reconstruction of two‐dimensional hyperpolarized 3He lung ventilation images using prior knowledge. When compared against a standard compressed sensing reconstruction, the proposed methods allowed acquisition of images with higher under‐sampling factors...
