Ron Kikinis Honored with KIT International Excellence Award 2026

Congratulations to Ron Kikinis, member of Helmholtz Imaging’s Scientific Advisory Committee, on receiving the 2026 International Excellence Award of KIT for his internationally renowned contributions to medical image processing, image-guided therapy, and biomedical informatics.

This image resembles an abstract mosaic or painting. It is composed of many irregular, crystal-like shapes in vivid shades of pink, yellow, turquoise, orange, blue, and black. The fragmented patterns create a textured appearance similar to stained glass or cracked ice illuminated by polarized light. It shows a longitudinal thin section of a sea ice core.

A highly detailed, abstract-looking microscopy image filled with tightly packed, irregular cell-like shapes. The scene is dominated by bright orange and blue outlines, with green streaks and patches weaving through the tissue, plus many small pink and purple clusters scattered throughout. The background is mostly black, which makes the fluorescent colors stand out strongly. Information about the image: To develop novel strategies targeting the tumor microenvironment in lung adenocarcinoma, the TME was stained for cell type specific markers and imaged on an Axioscan 7 Slidescanner.
