In cancer therapy a development of radiation therapy of tumors and metastases has been taking place since decades. In the beginning, the radiation treatments were carried out with radioactive sources. Since several years, linear accelerators have been established for the radiation therapy, which exploit the effect of bremsstrahlung of accelerated electrons. Still, there are high voltage radiotherapy devices for the treatment of less dangerous cancers. A good diagnostic device to identify tumors and metastases is a PET (Positron Emission Tomography). PET has been developed in nuclear medicine since years. Quantities of radioactively loaded substances (tracer) are injected into the human body to evaluate the metabolism by measuring the radioactive radiation. PET is good for functional diagnostics however it does not provide any good anatomical images.
