Abstract: Systems and methods are provided for provided for automated selection of UWFA images. A first set of images representing an early phase of a UWFA image acquisition and a second set of images representing a late phase of the UWFA image acquisition are received and segmented to provide a vascular structure map for each of the first set of images and the second set of images. An image quality metric is assigned to each of the first set of images and the second set of images from the vascular structure map associated with each image. An image of the first set of images having an extreme value for the image quality metric across the first set of images and an image of the second set of images having an extreme value for the image quality metric across the second set of images are selected.

Abstract: Systems and methods are provided for evaluating a quality of an OCT image. The system includes a processor and a non-transitory computer readable medium that stores instructions executable by a processor to evaluate the quality of the OCT image. The executable instructions include an imager interface that receives an OCT image from an associated OCT imager and a feature extractor that generates at least one feature from the OCT image. An image evaluator determines an image quality metric from the at least one feature, and a user interface provides an output representing the image quality metric to a display.

Abstract: Systems and methods are provided for fully automated quality assessment of ultra-widefield angiography images. A series of ultra-widefield angiography images of a retina of a patient are obtained and each of the series of ultra-widefield angiography images are provided to a neural network trained on a set of labeled images to generate a quality parameter for each of the series of ultra-widefield angiography images representing a quality of the image. Each of the set of labeled images are assigned to one of a plurality of classes representing image quality. A user interface provides an instruction to a user to obtain a new series of ultra-widefield angiography images of the retina of the patient if no image of the series of ultra-widefield angiography images has a quality parameter that meets a threshold value.
