The present disclosure relates in general to nuclear medicine and generators for the production of radiopharmaceuticals for medical use. In particular, present disclosure relates to a generator column that resists high heat such as depyrogenation and sterilization. This allows some steps of the preparation of the column to be performed in a non-sterile environment. This also allows the generator column to be reusable. The present disclosure further describes methods for the preparation of a generator where a parent radioisotope is charged on the column matrix before or after the matrix is loaded in the column.

Methods for setting up, maintaining and operating a radiopharmaceutical infusion system, that includes a radioisotope generator, are facilitated by a computer of the system. The computer may include pre-programmed instructions and a computer interface, for interaction with a user of the system, for example, in order to track contained volumes of eluant and/or eluate, and/or to track time from completion of an elution performed by the system, and/or to calculate one or more system and/or injection parameters for quality control, and/or to perform purges of the system, and/or to facilitate diagnostic imaging.

A radioisotope elution system is provided. The radioisotope elution system may comprise a controller that is configured to calculate the available amount of daughter radioisotope at any time during establishment of the equilibrium for decay of the parent radioisotope into its daughter radioisotope. The radioisotope elution system may comprise a controller that is configured to schedule various patient infusions planned for the next following days and weeks in accordance with the available amount of daughter radioisotope on each day. The elution system may also comprise a controller that is connected to the imaging software of a radioisotope imaging device, where the radioisotope imaging device is arranged for imaging the patient or a region of the patient; and the controller is configured to start an image acquisition at a predetermined time.

A nuclear medicine infusion system (10) may be used to generate and infuse radioactive liquid into a patient undergoing a diagnostic imaging procedure. In some examples, the infusion system includes a frame (30) that carries a radioisotope generator (52) that generates radioactive eluate via elution. The frame may also carry a beta detector (58) and a gamma detector (60). The beta detector can be positioned to measure beta emissions emitted from the radioactive eluate supplied by the generator. The gamma detector can be positioned to measure gamma emissions emitted from a portion of the radioactive eluate to evaluate a safety of the radioactive eluate delivered by the infusion system.

Disclosed are new configurations of a rubidium elution system that offer several advantages. The rubidium elution systems of the present disclosure comprise an assembly including a .sup.82Sr/.sup.82Rb generator, an activity detector, a waste container, a pump, a sensor, a tubing circuit, at least one valve, where the waste container is located in the lower section of the assembly. More particularly, the top surface of the waste container compartment is either below the top surface of the generator compartment, or the waste container is at the same elevation than the generator or below the pump.

Disclosed herein are rubidium elution systems comprising a primary assembly including a .sup.82Sr/.sup.82Rb generator, an activity detector, a waste container, a pump system, a sensor, a tubing circuit, at least one valve, and a computer; and a dose calibrator outside the primary assembly. The system may have an interface for configuring the dose calibrator, and a locking means for preventing access to the interface and reconfigurations of its parameters. Moreover, the dose calibrator may be in electronic communication with the computer of the system. Furthermore, the electronic communication can be embodied with an electronic cable having a breakaway connector. Also, the dose calibrator may be positioned on a mobile platform.

Infusion system configurations and assemblies facilitate routing of infusion circuit tubing lines. Tubing lines are routed into and out from compartments of a shielding assembly for the infusion system, at locations which prevent kinking and/or crushing of the lines, and/or provide for ease in assembling the circuit. A plurality of the lines may be held together by a support frame to form a disposable infusion circuit subassembly, that can further facilitate routing of the lines.
