Two-dimensional projection 3He MR images of human lungs, obtained using the open-access human MRI system, with subjects positioned as shown in Figure 2. a) Image obtained while the subject was lying horizontally, in a supine orientation. b) Image acquired while the subject was sitting vertically. Both images visualize the lungs as if looking at the subject from the front — i.e., the subject’s right lung lobe is on the left of the image. Imaging parameters: B0 = 6.5 mT, Larmor frequency = 210 kHz, FOV = 50 cm, NEX = 1, flip angle = 5°, TE/TR = 28.5/85.8 ms. Data size = 128 × 64, zero-filled to 128 × 128, total scan time ~ 4 s.
