Latest Patents
One of his latest patents is titled "Magnetic resonance angiography using undersampled 3D projection imaging." This invention employs a 3D projection reconstruction pulse sequence to acquire contrast-enhanced magnetic resonance angiography (CEMRA) images. In one application, an undersampled, high-resolution abdominal CEMRA image is acquired in a single breathhold. In another application, a series of undersampled image frames are collected during a CEMRA dynamic study. Each image is produced by combining peripheral k-space data from adjacent image frames with the central and peripheral k-space data of an acquired image frame.
Another significant patent by Barger is "Phase contrast imaging using interleaved projection data." This invention involves acquiring a magnetic resonance angiogram (MRA) using a pulse sequence that samples k-space at a projection angle. The acquired NMR signal is sensitized to spin motion with a bipolar motion encoding gradient. The pulse sequence is repeated to sample k-space at a set of different projection angles. A phase image is reconstructed from the acquired NMR signals using a filtered backprojection technique. Additional sets of projections with different motion encoding directions are acquired at interleaved projection angles, and the reconstructed phase images are combined to provide a velocity image.
