When it comes to radiotherapy, the MAASTRO Clinic leads the way internationally in the fields of biology and translational research. MAASTRO works closely with and Maastricht University, and the GROW School for Oncology and Developmental Biology in particular. Research successes at MAASTRO Lab and Fysica often become world-first clinical trials at the MAASTRO Clinic. This enables MAASTRO to continuously improve the concept of individualized radiotherapy. Special decision-supporting software assists physicians in choosing the best treatment for each patient. This Computer Assisted Theragnostics program is being adopted elsewhere in Europe and there are plans to use it elsewhere in the world as well.
