In-situ-generated solid radiation source based on Tungsten 188 /Rhenium 188 and use thereof

The use of radiotherapy is quite common in modern medicine. Radiotherapy is used for a variety of uses, such as for post-surgery treatment of tumors, for various types of cancer therapy and, lately, the art has found that radiotherapy can be useful in preventing restenosis in patients treated for coronary diseases. Restenosis has been treated so far by short-term irradiation with radioactive sources located in catheters and wires, and by long-term irradiation with implanted devices, such as stents. A radiotheraputical source of Rheniumcomprises metallic Tungstenor a metal oxide of Tungsten. Therapeutic device using Rheniumcomprise a radioactive source for the in situ generation of Rheniumfrom Tungsten.
