Research needed for improving heavy-ion therapy

The large interest in heavy-ion therapy is stimulated from its excellent clinical results. The bases of this success are the radiobiological and physical advantages of heavy-ion beams and the active beam delivery used for an intensity-modulated particle radiotherapy (IMPT). Although heavy-ion therapy has reached a high degree of perfection for clinical use there is still large progress possible...

Synthetic diamonds for heavy-ion therapy dosimetry

In this paper we report on first results obtained using polycrystalline CVD diamond detectors irradiated with heavily ionizing particles at GSI. At the UNILAC accelerator, ions with energies near the Bragg-Peak have been stopped inside the material whereas at the heavy-ion therapy facility of GSI these detectors are operated in transmission mode and have been studied in a carbon beam from SIS w...

Needed: Global Collaboration for Comparative Research on Cities and Health

Over half of the world’s population lives in cities and United Nations (UN) demographers project an increase of 2.5 billion more urban dwellers by 2050. Yet there is too little systematic comparative research on the practice of urban health policy and management (HPAM), particularly in the megacities of middle-income and developing nations. We make a case for creating a global database on citie...

Heavy-Ion Therapy at GSI: Progress Report

In 2000 three Carbon beam blocks were used to treat 32 patients suffering from skull base tumors such as chordomas, chondrosarcomas, adenoid cystic carcinomas and other less frequent indications. Partially these ongoing clinical trials have reached phase II level. In total 73 patients have been treated within this experimental programme and the overwhelming part of treatments had a curative int...
