Efficient MR fingerprinting using B-splines to improve (quantitative) MRI
Background/problem Magnetic resonance imaging (MRI) is a state-of-the-art diagnostic imaging modality which beneficially features excellent soft tissue contrast and lacks use of ionizing radiation. In clinical practice, MRI generates contrast-weighted images based on the intrinsic tissue parameters of the subject, which are then interpreted by a radiologist....

BystandAR: Protecting Bystander Visual Data Privacy in Augmented Reality Systems
THE CHALLENGE Well-intentioned AR users often unknowingly violate bystander privacy by collecting and sharing sensitive data. Some apps use machine learning to make inferences without user knowledge, further compromising privacy. The current permissions within the state of the art are flawed as colluding apps deceive users to access and share data...

Control of Probe Beam Duration in Single Wavelength Monitoring of Hologram Diffraction Efficiency
This technology is a novel technique for monitoring the diffraction efficiency of Volume Holographic Elements (VHOEs) in real time. The technique works by using a shutter or chopper to periodically block one of the exposing beams during the fabrication and measuring the power of the diffracted beam using a power meter. This technique has the potential...
