Potential medical applications of the plasma focus in the radioisotope production for PET imaging

The Investigation Capability of Plasma Focus Device for <sup>13</sup>N Radioisotope Production by Means of Deuteron Experimental Spectrum

“…where N is the number of nitrogen 13 nuclei per cubic centimeter; The data of cross section of the reaction 12 C (d,n) 13 N is obtained from EXFOR data base [8] and SRIM code [9] is used to calculate reaction stopping power (Figure 1). In Figure 1, the blue points are experimental data (by means SRIM code) and the red curve is the fitted diagram on experimental data.…”

“…The number of 13 N nuclei can be calculated by replacing Equation (4) in Formula 2. Then, the activity is calculated.…”

“…Short-lived radioisotopes (SLR) such as 11 C, 13 N, 15 O, 18 F usually have medical applications, particularly in positron emission tomography (PET). These radioisotopes are obtained through bombarding appropriate targets by ion beams produced in accelerators.…”

“…A good candidate for studying radioisotope production within the plasma focus is the nuclear reaction of 12 C (d,n) 13 N. The advantages of this reaction are high cross section, low threshold energy, short half-life, and the availability of target materials [3].…”

“…In this study, first the activity of a set of experimental spectra of deuteron produced by NX2 plasma focus device which has been measured by magnetic spectrometer [7] is calculated and then the optimizing conditions of 13 N production is investigated.…”
