With a total of 2 patents, Arai's work has advanced the understanding and capabilities of cardiac imaging.

Latest Patents

Arai's latest patents include a method for extracting deformations from velocity-encoded magnetic resonance imaging. This innovative technique involves conducting an MRI scan where velocity-encoded NMR data is acquired for a slice through the heart. The process includes reconstructing velocity images and magnitude images at multiple cardiac phases, forming masks using the magnitude images, and applying these masks to isolate the left ventricle. Rigid body motion is calculated and subtracted from the masked velocity images to indicate deformation of the left ventricle. Another significant patent is related to the retrospective ordering of segmented MRI cardiac data using cardiac phase. This method reconstructs multiphase MR images that accurately depict the entire cardiac cycle by modifying a segmented, gradient-recalled-echo sequence to acquire data continuously.
