Motion degradation is a central problem in Magnetic Resonance Imaging (MRI). This work addresses the of how to obtain higher quality, super-resolved motion-free reconstructions from highly undersampled MRI data. In this work, we present for first time variational multi-task framework that allows joining three relevant tasks MRI: reconstruction, registration and super-resolution. Our takes set m...

BACKGROUND AND PURPOSE CT is a ubiquitous, efficient, and cost-effective method to evaluate pediatric ventricular size, particularly in patients with CSF shunt diversion who often need emergent imaging. We therefore sought to determine the minimum dose output or CT dose index required to produce clinically acceptable examinations. MATERIALS AND METHODS Using a validated noise insertion method...

One of the most difficult aspects of deriving an information management plan for a large knowledge based enterprise is to determine what information people require to do their various tasks as well as help them expand and update their existing knowledge. Achieving this goal can be time consuming. To speed up and yet effectively define information needs, an electronic survey tool was designed to...

  The anterior cruciate ligament (ACL) is composed of two bundles, which work together to provide both antero-posterior and rotatory stability of the knee. Understanding the anatomy and function of the ACL plays a key role in management of patients with ACL injury. Anatomic ACL reconstruction aims to restore the function of the native ACL. Femoral and tibial tunnels should be placed in their an...

Hot Isostatic Pressing (HIP'ing) is one of several processes used for consolidating porous materials (such as metal powders) to high density. The equations describing the HIP'ing system dynamics are immensely complicated and highly nonlinear, thus complicating any controller design for the system. Further complications arise due to the fact that one of the system's states, grain size, cannot be...
