Immune diseases, such as rheumatism or psoriasis, are systemic diseases that often affect several organ systems simultaneously. An interdisciplinary approach is absolutely necessary for the optimal care of patients. This is implemented at Fraunhofer ITMP in the concept of the 4D Clinic. Professor Frank Behrens, deputy director of the institute, describes in the Fraunhofer podcast why the 4D Clinic is unique and what the concept can achieve for patients and research.
