Fast scans

Fast MRI for repeated scans

Radiological assessment of brain disease progression and response to therapy is often performed with repeated MRI scans acquired every few weeks/months. In these longitudinal studies, each scan is acquired anew without taking into account the information present in previous scans. However, many image regions remain unchanged from one time point to the next, making the difference image between t...

Fast Scans on Key-Value Stores

Key-Value Stores (KVS) are becoming increasingly popular because they scale up and down elastically, sustain high throughputs for get/put workloads and have low latencies. KVS owe these advantages to their simplicity. This simplicity, however, comes at a cost: It is expensive to process complex, analytical queries on top of a KVS because today’s generation of KVS does not support an efficient w...

EARS: Toward Fast Analysis of 3D Human Scans

We present the Enhanced Anthropometric Rating System (EARS), an integrated collection of tunable semi-automatic procedures to compute, visualize, and evaluate the geometric information of a 3D human body scan. To the best of our knowledge, EARS is the first complete system dedicated to fast evaluation and analysis of the quality of a human scan data. EARS is able to detect and remedy scan flaw...

Fast Semi-Automatic Plexiform Neurofibroma Tumor Segmentation in MRI Scans

Fast Concomitant Gradient Field Correction for Spiral Scans

Introduction: A major drawback to non-Cartesian imaging is the off-resonance blurring effects. Common linear techniques that remove the distortion effects are not sufficient, because the high order concomitant gradient fields are nontrivial for low fields and for scans that are more than 5 cm off isocenter [1]. Previous correction algorithms either are slow or do not take into account the known...
