Patent Number: 
Section: claims

1. An elution system comprising:a radioisotope generator configured to release a daughter radioisotope during elution with an eluant thereby producing an eluate containing the daughter radioisotope, the daughter radioisotope being produced from radioactive decay of a parent radioisotope contained within the radioisotope generator;an eluate line configured to receive and convey eluate eluted from the radioisotope generator;an accumulator structure positioned downstream from the radioisotope generator and in fluid communication with the eluate line, the accumulator structure being configured to capture a larger amount of parent radioisotope than daughter radioisotope. 2. The system of claim 1, wherein the radioisotope generator comprises a generator column loaded with the parent radioisotope and the accumulator structure comprises a second column devoid of the parent radioisotope. 3. The system of claim 2, wherein the generator column and the second column are fabricated from a same material. 4. The system of claim 3, wherein the same material from which the generator column and the second column are fabricated is selected from the group consisting of stannic oxide, tin oxide, an organic matrix, and combinations thereof. 5. The system of claim 1, wherein the accumulator structure is configured to capture the larger amount of parent radioisotope than daughter radioisotope by preferentially binding any parent radioisotope present in the eluate received via the eluate line. 6. The system of claim 1, wherein the radioisotope generator comprises one of a 99Mo/99mTc generator, a 68Ge/68Ga generator, and a 82Sr/82Rb generator. 7. The system of claim 1, wherein the radioisotope generator is a 82Sr/82Rb generator. 8. The system of claim 1, further comprising a base frame with wheels, wherein the radioisotope generator, eluate line, and accumulator structure are mounted on the base frame so as to be movable. 9. The system of claim 1, further comprising an eluant line configured to supply the eluant to the radioisotope generator. 10. The system of claim 1, wherein the accumulator structure is configured to receive eluate from the eluate line so that the eluate flows at least one of through and over the accumulator structure.
