Since November 2019, Gremse-IT and six other project partners have been working on the Taktira project, which is supported by funding from the state of NRW and the EU. Taktira stands for the "Development of an improved immunotherapy with few side effects based on tumor-targeted and activatable immune reaction initiation". In this project, Gremse-IT is developing and researching software methods for the reconstruction, visualization, and quantitative evaluation of multimodal longitudinal image data in order to be able to non-invasively assess drug biodistribution, local accumulation, and effect of tumor-specific and immunotherapeutic agents.
