摘要:
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 method of delivering a radioactive liquid includes, performing an initialization, including; extracting at least a first amount of a radioactive liquid from a source of radioactive liquid, measuring a radioactivity level for the first amount of radioactive liquid, and performing a calibration phase. The calibration phase includes, extracting a second amount of radioactive liquid from the source of radioactive liquid wherein the second amount is calculated based on the radioactivity level of the first amount to provide a total dose of radioactive liquid having a predetermined radioactivity level, and delivering the total dose and performing at least one more calibration and delivery phases.

摘要:
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.

The nanoparticle for internal radiation therapy.
摘要:
A device and a method for accurate dispensing of a radioactive liquid are disclosed. A source of a radioactive liquid and a source of a flushing liquid are selectively connected to a fluid delivery path by way of valve means. An activity metering unit is operable to determine a level of radioactivity in a metering section of the fluid delivery path downstream from the valve means. The device is operated by transporting a first amount of radioactive liquid to the metering section, using the activity metering unit to measure a reference level of radioactivity, calculating a second amount of the radioactive liquid still to be delivered such that the first and second amounts of radioactive liquid together have some predetermined level of radioactivity, and delivering the first and second amounts of radioactive liquid to the destination.
