Abstract: In exemplary implementations of this invention, an aberrometer is used to measure the refractive condition of any eye. An artificial light source emits light that travels to a light sensor. Along the way, the light enters and then exits the eye, passes through or is reflected from one or more spatial light modulators (SLMs), and passes through an objective lens-system. The SLMs modify a bokeh effect of the imaging system (which is only visible when the system is out-of-focus), creating a blurred version of the SLM patterns. The light sensor then captures one or more out-of-focus images. If there are refractive aberrations in the eye, these aberrations cause the SLM patterns captured in the images to be distorted. By analyzing differences between the distorted captured patterns and the undistorted SLM patterns, refractive aberrations of the eye can be computed and an eyewear measurement generated.

Abstract: A method for computing global longitudinal strain from cine magnetic resonance (MR) images includes automatically detecting landmark points in each MR long axis image frame included in a cine MR image sequence. A deformation field is determined between every pair of frames based on the landmark points. Myocardial pixels in the frames are labeled using a deep learning framework to yield myocardium masks. These myocardium masks are propagated to each frame using the deformation fields. A polar transformation is performed on each of the masked frames. The contours of the myocardium in each transformed frame are computed using a shortest path algorithm. Next, longitudinal strain is calculated at every pixel in the myocardium for the polar frames using the contours of the myocardium. Then, global longitudinal strain is computed by averaging the longitudinal strain at every pixel in the myocardium of the transformed frames.

The spectral unmixing then uses an iterative solution process to separate spectra for the multiple fluorescent light sources, and provides a spectrum and/or a spatial distribution map for at least one of the internal light sources.
