Microfluidic radiopharmaceutical production system and process for synthesizing per run approximately, but not less than, ten (10) unit doses of radiopharmaceutical biomarker for use in positron emission tomography (PET). A radioisotope from an accelerator or other radioisotope generator is introduced into a reaction vessel, along with organic and aqueous reagents, and the mixture heated to synthesize a solution of a pre-selected radiopharmaceutical. The solution is purified by passing through a combination of solid phase extraction purification components, trap and release components, and a filter. The synthesis process reduces waste and allows for production of biomarker radiopharmaceuticals on site and close to the location where the unit dose will be administered to the patient. On-site, as-needed production of radiopharmaceuticals in small doses reduces the time between synthesis of the radiopharmaceutical and administration of that radiopharmaceutical, minimizing loss of active isotopes through decay and allowing production of lesser amounts of radioisotopes overall.


HPLC-based quality control systems to perform quality control testing on a radiopharmaceutical solution shortly after synthesis. An HPLC-based quality control system makes efficient use of sample volume and is compatible with a variety of radioisotopes and radiopharmaceutical compounds. In several embodiments, the automated nature of an HPLC-based quality control system allows for quality control tests to be conducted quickly and with minimal impact on user workflow. When used as part of an integrated PET biomarker radiopharmaceutical production system, the present general inventive concept permits a manufacturer to produce product and conduct quality control tests with lower per dose costs.

A target assembly to produce radioisotopes for the synthesis of radiopharmaceuticals. The target assembly includes a target vessel with a target chamber adapted to receive a target material. A thin cover sheet of particle-permeable material covers the target chamber. In a bombardment process, a high-energy particle beam generated by a cyclotron or particle accelerator strikes the thin cover sheet, whereby at least some of the particles from the particle beam penetrate to the target chamber so as to interact with the target material, altering the nuclear makeup of some of the atoms in the target material to produce radioisotopes.
