Abstract:
1. An ophthalmic optical coherence tomography (OCT) system, comprising: an OCT engine including optics and electronics configured to acquire data used to generate OCT images of a subject; and a portable housing including a portable scanning interface device in communication with the OCT engine, comprising at least one mirror configured to scan light in at least two non-co-planar directions and at least one lens set coupled to the at least one mirror and configured to receive light from the at least one mirror, to focus the received light onto a structure of an eye of the subject, and to receive light that is scattered or reflected from the structure of the eye; an optical fiber connecting the housing including the portable scanning interface device to the OCT engine, the optical fiber being configured to guide light from the OCT engine to the portable scanning interface device; means for aligning the housing including the portable scanning interface device to the structure of the eye without using a chinrest to stabilize the subject; means for controlling spacing between the portable interface device and the structure of the eye without using a chinrest to stabilize the subject; means for setting acquisition parameters for imaging the structure of the eye; means for acquiring, processing and displaying volumetric OCT image data of the structure of the eye in real-time; and means for making the OCT images relatively insensitive to changes in the optical fiber connecting the OCT engine to the housing including the portable scanning interface device that occur during imaging without using a chinrest to stabilize the subject.
