Sealed Radionuclide and X-Ray Sources in Nuclear Medicine
- 1.7k Downloads
Apart from the radiopharmaceuticals that are administered to the patient as part of an examination or treatment , nuclear medicine uses different radiation sources, both as part of the examination procedures and for quality control of the equipment involved. In connection with the examination, radiation sources are used as markers and for measurements of transmission of radiation through the body as a basis for attenuation correction. The performance of activity meters, scintillation cameras, and positron emission tomographic (PET) scanners are all monitored by the use of solid radiation sources. It is preferable that these sources have long half-lives to simplify constancy checks and to avoid frequent costly replacements.
