This book presents the proceedings of the 11th International Conference on Information Technology in Biomedicine ITIB 2026. It has already been 18 years since the inception of ITIB which now has a long history published novel research, scientific findings, and innovative solutions by hundreds of international and national researchers. The collection reflects the dynamic development of computational methods supporting contemporary biomedicine and continues the long-standing tradition of ITIB Conference in bringing together diverse scientific communities. This book illustrates how information technology increasingly shape diagnostic and therapeutic practice and the broader understanding of human physiology.

 A significant portion of this book is devoted to medical image analysis across multiple modalities, including CT angiography, MR, HFUS, OCT, X-ray imaging, digital radiography, and histopathology. The studies demonstrate the application of advanced segmentation frameworks, multimodal fusion strategies, and enhancement algorithms. By addressing both methodological challenges and clinical relevance, these works emphasize the sustained impact of algorithmic innovation on diagnostic precision and workflow automation.
