Abstract: A method for generating transmission information in a time-of-flight positron emission tomography (PET) scanner having a patient tunnel and a plurality of PET detector rings. The PET scanner uses continuous bed motion to move a patient bed and patient through the patient tunnel. The patient receives a positron-emitting radioisotope dose prior to undergoing a PET scan. The method includes storing a positron-emitting radioisotope in a radiation shielded container. The method also includes moving the radioisotope into a stationary vessel located adjacent to the PET detectors and within a field of view of the PET scanner at substantially the same time that the patient receives the radioisotope dose to form a stationary transmission source wherein transmission information is generated while the bed undergoes continuous bed motion. Further, the method includes withdrawing the radioisotope from the vessel when the PET scan is complete and storing the radioisotope in the container.

Abstract: An apparatus for manufacturing a radioisotope comprises a container. The container comprising a portable neutron source and a solution that comprises a particular isotope. The portable neutron source is surrounded by the solution. The solution comprises at least one of copper phthalocyanine or copper salicylaldehyde o-phenylene diamine. The portable neutron source emits neutrons that react with the particular isotope resulting in the transformation of the particular isotope into the radioisotope.

Abstract: Disclosed are a method and apparatus for making a radioisotope and a composition of matter including the radioisotope. The radioisotope is made by exposing a material to neutrons from a portable neutron source.

Abstract: A method and device for reducing positron emitter isotope labeled CO2 to positron emitter isotope labeled CO generally includes introducing a volume of positron emitter isotope labeled CO2 into a first heated reaction vessel comprising a metal oxide, such as Iron (II) Oxide such that the CO2 is reduced to CO upon contact with the Iron (II) Oxide. The volume is then transferred to a second reaction vessel to remove any un-reacted CO2, preferably, via a soda-lime trap. The volume is then transferred to a target, e.g., a storage vessel or subject. The CO2 includes one of [11C] or [15O]. The first reaction vessel is, preferably, heated to a temperature of between 900 and 1000° C., and more preferably, to between 925 and 975° C., and even more preferably, to approximately 950° C. Preferably, the Iron (II) Oxide powdered and has a particle size of about ?10 mesh.

Abstract: A beta detector assembly for use in the synthesis and analysis of radiopharmaceuticals, such as in microfluidic radiochromatography. The beta detector assembly includes a base, preferably fabricated from glass so as to take advantage of electroosmotic flow, that serves as the body of the beta detector assembly. A microfluidic channel passes through the length of the base. A solid-state charge particle detector, for detecting beta particles, is provided and is positioned with respect to the base so as to receive beta particles. A portion of the base is disposed between the microfluidic channel and the solid-state charge particle detector and has a thickness that is selected to substantially allow transmission of beta particles there thru for detection by the charge particle detector. In one embodiment, the base is fabricated of glass. In another embodiment, the base is fabricated of silicon such that the base and the solid-state charge particle detector are integral.

Abstract: The invention provides a method and apparatus for preparation of radiochemicals wherein the reaction that couples the radioactive isotope to the reactive precursor to form a positron-emitting molecular imaging probe is performed in a microfluidic environment.
