Abstract: Systems and methods for generating a three-dimensional image of an object from multiple two-dimensional images acquired using a magnetic resonance imaging (“MRI”) system are provided. The three-dimensional image has high spatial resolution in all three spatial dimensions. The multiple two-dimensional images can be acquired in one or more orientations (e.g., axial, coronal, sagittal, oblique). The in-plane resolution of these images can be several times finer than the through-plane resolution (i.e., the slice thickness). The images are Fourier transformed along their respective slice orientation direction and processed using the slice profile to generate a Fourier representation of the three-dimensional image with the target spatial resolution. Inverse Fourier transforming this Fourier representation generates the desired three-dimensional image.

Abstract: This document describes methods and devices for using electrical stimulation to control physiological functions such as breathing of patients suffering from respiratory impairment. For example, this document describes methods and devices for generating effective breaths and airway protection by determining times and depths of breaths in accordance with physiological demand, and coordinating respiratory muscle stimulation with the breaths to control breathing.
