摘要： Methods for improved acquisition and processing of optical coherence tomography (OCT) angiography data are presented. One embodiment involves improving the acquisition of the data by evaluating the quality of different portions of the data to identify sections having non-uniform acquisition parameters or non-uniformities due to opacities in the eye such as floaters. The identified sections can then be brought to the attention of the user or automatically reacquired. In another embodiment, segmentation of layers in the retina includes both structural and flow information derived from motion contrast processing. In a further embodiment, the health of the eye is evaluating by comparing a metric reflecting the density of vessels at a particular location in the eye determined by OCT angiography to a database of values calculated on normal eyes.

摘要： After OCT scans are acquired, error compensation is be applied anew by identifying motion tracking data that was collected simultaneously with (or closest in time to) each acquired OCT scan. The effects of any previously applied motion tracking information is removed from an OCT scan before applying the new motion tracking data, which may provide higher resolution motion tracking.

摘要： The system, method and device includes an optical coherence tomography (OCT) system switchable between single scan mode or multi-scan mode. This is achieved by use of multiple beam splitters to produce multiple OCT beams, but the system still uses a single light source, a single sample arm, and single reference arm to achieve a compact, more cost effective, system. Additionally presented is a spectral domain OCT system with a spectrometer having multiple grating, each providing a different depth and/or resolution imaging capability.

摘要： A medical ophthalmic system uses a patient-specific face mask to establish a predefined alignment between the ophthalmic system and an eye of a patient. The patient-specific face mask may optionally provide a light proof enclosure for the eye. The face mask may be coupled directly to an ophthalmic device, or its housing/enclosure, of the ophthalmic system. The face mask may be 3D printed based on a 3D model of the patient's face.

摘要： Systems and methods for improved interferometric imaging are presented. One embodiment is a partial field frequency-domain interferometric imaging system in which a light beam is scanned in two directions across a sample and the light scattered from the object is collected using a spatially resolved detector. The light beam could illuminate a spot, a line or a two-dimensional area on the sample. Additional embodiments with applicability to partial field as well as other types of interferometric systems are also presented.

摘要： A system and method for ophthalmic motion tracking. An anchor point and multiple auxiliary points are selected from a reference image. Individual live images in a series of images are then searched for matches of the anchor point and auxiliary point. First, the anchor point is found, and then searches for individual auxiliary points is limited to a search window defined by the known distance and/or orientation of the sought auxiliary point relative to the anchor point.

摘要： Systems and methods for Broad Line Fundus Imaging (BLFI), an imaging approach that is a hybrid between confocal and widefield imaging systems, are presented. These systems and methods are focused on improving the quality and signal of broad line fundus images or imaging methods to create high contrast and high resolution fundus images. Embodiments related to improved pupil splitting, artifact removal, reflex minimization, adaptable field of view, instrument alignment and illumination details are considered.

摘要： Various techniques for providing a low-cost ophthalmic imaging system, such an OCT or fundus imagers are presented. Cost is reduced by using a K-minor as a scanning component. The K-mirror is positioned at a retina conjugate. A beam splitter is positioned at the pupil conjugate and may be used to provide pupil splitting functionality. The beam splitter's shape and area conform to the focal light footprint of an illumination source such that it spans only a fraction of a collection window. 2D FFT is applied to capture spectra for purposes of selectively removing complex conjugate components and for extracting patient pupil to system collection pupil alignment. Consequently, pupil alignment is achieved by use of captured OCT data without the need for additional pupil cameras.
