Application of Programmable Logic Controller ( PLC ) brings CIAE-30 compact cyclotron into entirely automatic control, from cyclotron start-up until required beam current obtained at target can be performed with a single function key. The main parameters are sequentially set-up and regulated by PLC requiring no operators during routine production. High anti-interference ability, reliable safety...

Background: PET/CT imaging using [18F]-FDG is utilized in clinical oncology for tumor detecting, staging and responding to therapy procedures. Essential consideration must be taken for radiation staff due to high gamma radiation in PET/CT and cyclotron center. The aim of this study was to assess the staff exposure regarding whole body and organ dose and to evaluate environment dose in PET/CT an...

background: 66ga (t1/2=9.49 h, β+: 4.153 mev, γ: 511, 834, 1039, 2752 kev) has a wide range of applications in different fields of medical sciences. production of 66ga became one of our main interests, according to its increasing applications in nuclear medicine, particularly in pet imaging. materials and methods: 66 zn (p,n)66ga reaction was determined as the best choice for the production of ...

A new strategy is described for the determination of amino acid sequences of unknown peptides. Different from the well-known but often inefficient de novo sequencing approach, the new method is based on a two-step process. In the first step the amino acid composition of an unknown peptide is determined on the basis of accurate mass values of the peptide precursor ion and a small number of accur...

Schönherr, Gabriele Strong magnetic fields of accreting neutron stars — Modeling cyclotron lines — Accreting neutron stars in X-ray binaries are unique astrophysical laboratories for studying the physics of matter under extreme conditions. Not only does their compact nature lead to an amount of gravity only topped by black hole systems; they can also possess extreme magnetic fields, exceeding t...

Positron emission tomography in conjunction with radiopharmaceuticals labeled with positron emitting radionuclides opens the possibility of visualizing in vivo in an atraumatic way fundamental parameters of metabolism in man. The main positron emitting radioisotopes carbon-II, oxygen-IS, nitrogen-13 and fluorine-IR used for labeling radiopharmaceuticals (sugars, aminoacids, fatty acids and drug...
