摘要: A method for improving an OCT image of an object such as the retina of an eye, using optical coherence tomography by an imaging beam path. In order to suppress shadowing effects due to a surgical instrument moved in the imaging beam path, a time series of OCT images is produced. For an OCT image to be corrected, an area of the object lying in the image and shadowed by the instrument is determined. Another earlier OCT image in which the area of the object is not shadowed is searched in the time series. Image information for the area of the object is read from the earlier OCT image. A corrected OCT image is produced by inserting the read-image information into the OCT image to be corrected, wherein in the OCT image to be corrected, the image information replaces the area of the object which is shadowed by the instrument.

摘要: An eye surgery system 1 comprises microscopy optics 3 and an OCT device 5 to generate a light-optical image and an OCT image of an eye fundus 11, a controller 29 and a visualization system 13, 41, 83. The controller comprises a data interface 97 for receiving a preoperative OCT image and may control the visualization system to display a representation of the received preoperative OCT image. The controller may control the OCT device 5 to record an intraoperative OCT image and may control the visualization system to display a representation of the recorded intraoperative OCT image. The controller may adjust a magnification of the representation of the intraoperative OCT image and/or a magnification of the representation of the preoperative OCT image so that the magnifications of the representation of the intraoperative OCT image and the magnification of the representation of the preoperative OCT image are equal.

摘要: An ophthalmologic system comprising and eye tracker and an OCT system. A method of operating the ophthalmologic system comprises: providing data representing a placement of a first B-scan performed on an eye relative to the eye; performing a measurement on the eye using the eye tracker; determining a placement of the eye relative to the ophthalmologic system based on the measurement using the eye tracker; placing the eye relative to a reference placement of the OCT system based on the provided data and the determined placement; performing A-scans on the eye at at least three A-scan positions; determining a placement of a second B-scan relative to the OCT system based on at least one of the at least three A-scans and the provided data such that the second B-scan and the first B-scan have a substantially same placement relative to the eye; and generating a representation of the second B-scan.
