Energetic ion beam emission enhancement for short lived radio isotopes (SLRs) production by using a low energy dense plasma focus device.

Abstract: ​Short lived radioisotopes (SLR) such as 13N, 17F, 18F, 15O, and 11C have been produced through either external solid (exogenous method) or high atomic number gas (endogenous method) targets. These radioisotopes are positron emitter used for positron emission tomography (PET) imaging. Positron emission tomography is an imaging technique that shows the distribution of positron-emitting nuclides in a patient’s body. SLRs (10 min. to 100 min. half lifetime) must be produced in proximity of treatment or diagnostic facilities .Cyclotron is often used for this purpose. A new Dense Plasma Focus machine ( DPF) is being develop at University of Saskatchewan to produce Nitrogen-13 radioisotope. Nitrogen-13 is used to tag ammonia molecules for PET myocardial perfusion imaging. Dense Plasma Focus machine ( DPF) can generate high energetic ion with suitable flux to produce Nitrogen-13 through the 12C(d, n)13N nuclear reaction. In this presentation I am going to introduce DPF machine, progress of the project and the future approach.
