Abstract

The present invention relates to a system for visualizing OCT signals, comprising a display means designed for the time-resolved display of image data and a control unit, the control unit being configured to receive a time-resolved OCT signal of a selected field of view of a sample from an OCT system, to ascertain a time-resolved OCT image with a virtual shadow on the basis of the OCT signal, with the virtual shadow being generated in object-specific fashion on at least one area of the OCT image by a virtual irradiation of at least one object of the OCT image by means of a virtual light source, and to control the display means to display the time-resolved OCT image on the display means. The present invention also relates to a corresponding method for visualizing OCT signals.

Dependent claims

A system for visualizing OCT signals, comprising:

a display means designed for the time-resolved display of image data;
and
a control unit, which is configured
to receive a time-resolved OCT signal of a selected field of view of a sample from an OCT system;
to ascertain a time-resolved OCT image with at least one virtual shadow on the basis of the OCT signal, with at least one shadow-generating object of interest and at least one shadow-receiving area of interest being ascertained on the basis of the OCT signal or OCT image,
with the at least one virtual shadow being generated in object-specific fashion on the at least one shadow-receiving area of the OCT image by a virtual irradiation of the at least one shadow-generating object of the OCT image by means of a virtual light source;
and
to display the time-resolved OCT image on the display means,
with the control unit being further configured
to ascertain the at least one shadow-generating object of interest and/or the at least one shadow-receiving area of interest by way of a targeted segmentation of the OCT signal or OCT image, or
to segment a multiplicity of objects and/or areas in the OCT signal or OCT image and select the at least one shadow-generating object of interest and/or the at least one shadow-receiving area of interest therefrom.

8 more elements

A method for visualizing OCT signals, including the method steps of:

receiving a time-resolved OCT signal of a selected field of view of a sample from an OCT system, with the OCT signal including a multiplicity of tuples each representing a volume element of the sample and a scattering intensity corresponding to the volume element;
ascertaining a time-resolved OCT image with at least one object-specific virtual shadow, with at least one shadow-generating object of interest and at least one shadow-receiving area of interest being ascertained on the basis of the OCT signal or OCT image and with the at least one object-specific virtual shadow being generated on the at least one shadow-receiving area of the OCT image by a virtual irradiation of the at least one shadow-generating object of the OCT image by means of a virtual light source;
and
displaying the time-resolved OCT image on the display means,
with the at least one shadow-generating object of interest and/or the at least one shadow-receiving area of interest being ascertained by way of a targeted segmentation of the OCT signal or OCT image, or
with a multiplicity of objects and/or areas in the OCT signal or OCT image being segmented and the at least one shadow-generating object of interest and/or the at least one shadow-receiving area of interest being selected therefrom.
