Guinea pig lungs filled with polarized helium (24K JPEG)
An isotope of helium gas (He-3) produces intense MR signal when it is
hyperpolarized by a laser technique. The presence of this unique
gas makes the airways of the lung visible in an MR image.
This work was done in collaboration with physicists from
Princeton University.
Projection-reconstruction
of rat lungs (32K JPEG)
These images were collected using projection MRI.
Usually it is very hard to see lung tissue.
This sampling method
allows image information to be collected
before signal from the lung tissue fades away.
This work
was done in collaboration with physicists from
Stanford University. The heartbeat animation was made by carefully
synchronizing imaging with both the breathing and the heartbeat of a live
rat.
