摘要:
Systems and methods for eye tracking for motion corrected ophthalmic optical coherence tomography (OCT) are disclosed. According to an aspect, an imaging system includes an eye tracking device configured to determine movement of an eye. The imaging system also includes an OCT apparatus configured to generate OCT images of a retina of the eye. The OCT apparatus includes a scanner operable to be moved for relocating an OCT scan pivot at a pupil plane for image capture and during capture of the OCT images. The imaging system also includes a controller configured to control the scanner to relocate the OCT scan pivot at the pupil plane based on the determined movement of the eye.
摘要:
Whole eye optical coherence tomography (OCT) imaging systems and related methods are disclosed. According to an aspect, an OCT imaging system includes a source having an associated source arm path. Further, the OCT imaging system includes a reference arm coupled to the source arm. Further, the OCT imaging system includes a sample arm having an associated sample arm path and coupled to the source arm. The sample arm includes at least one optical component configured to simultaneously scan both an anterior and posterior portion of an eye of a subject.
摘要:
A method of performing computational image contrast from multidimensional data includes receiving a plurality of images of an object, with each image of the plurality of images having more than three dimensions, performing multi-dimensional registration of the plurality of images to generate a multi-dimensional dataspace, reducing dimensionality of the multi-dimensional dataspace to create an enhanced resolution and contrast image of a 3D space of the object using the plurality of images as registered in the multi-dimensional dataspace, and displaying the enhanced resolution and contrast image. In some cases, reducing the dimensionality of the multi-dimensional dataspace to create the enhanced resolution and contrast image of the 3D space of the object comprises utilizing at least one of variance, high-order statistics, entropy, principal component analysis, t-distributed stochastic neighborhood embedding, and neural networks using the plurality of images as registered in the multi-dimensional dataspace.
