Abstract
An apparatus for processing image data is disclosed. The apparatus includes one or more processors. The apparatus determines a feature in a cross-sectional image of a live tissue. The apparatus determines a superimposed image by superimposing a reference on the cross-sectional image or a subsequent cross-sectional image of the live tissue. The reference is based on the determined feature. An output interface outputs image data of the superimposed image for display.
Claims14
An apparatus for processing image data, comprising:
- one or more processors configured to:
- generate a cross-sectional image and a subsequent cross-sectional image of a live tissue;
- determine a feature in the cross-sectional image of the live tissue;
- determine a superimposed image by superimposing a first reference and a second reference on the cross-sectional image or the subsequent cross-sectional image of the live tissue, the first reference being determined based on the determined feature and the second reference being determined based on an offset from the first reference;
- identify a stable region and an unstable region of the determined feature, the unstable region corresponding to an area of surgical activity;
- and
- update the first reference in the subsequent cross-sectional image by tracking a position of the stable region, while disregarding changes in the unstable region;
- and
- an output interface configured to output image data of the superimposed image for displaying the superimposed image.
