1. A system for dispensing a fluid comprising:
- a peristaltic pump configured to force an aliquot of a radiopharmaceutical fluid from a fluid source into a fluid delivery channel;
at least one radioactivity sensor configured to measure a sample value of a radioactivity property of the aliquot;
a processor in communication with the peristaltic pump and the at least one radioactivity sensor; and
a non-transitory, computer-readable storage medium in operable communication with the processor, wherein the computer-readable storage medium contains one or more programming instructions that, when executed, cause the processor to;
receive the sample value of the radioactivity property of the aliquot,receive a source value of the radioactivity property for the fluid source,determine a sample volume of the aliquot based on a comparison of the sample value and the source value,determine a pump coefficient based on a comparison of the sample volume with an expected volume, wherein the pump coefficient is configured to indicate a volume of the radiopharmaceutical fluid forced into the fluid delivery channel per unit, andcontrol operation of the peristaltic pump to dispense a predetermined dose of the radiopharmaceutical fluid based on the comparison of the sample volume with the expected volume,wherein the sample volume of the aliquot is affected by at least one dimensional property of the fluid delivery channel.

Abstract
Methods and systems for dispensing a fluid using an automated fluid delivery system are disclosed. A pump may be configured to force an aliquot of fluid from a fluid source into a fluid delivery channel. A processor may receive values of a property for the aliquot and the fluid source of the aliquot, and may use these values to determine a volume of the aliquot. The determined volume is compared by the processor against an expected volume to establish the amount of fluid being pumped by the pump per unit, such as time or revolutions. The processor controls operation of the pump to dispense a predetermined dose based on the amount of fluid being pumped by the pump per unit.

18. A method of dispensing a radiopharmaceutical fluid, the method comprising:
-
providing a peristaltic pump configured to force an aliquot of a radiopharmaceutical fluid from a fluid source into a fluid delivery channel; receiving, by a processor, a source value of a radioactivity property for the fluid source and a sample value of the radioactivity property for the aliquot measured by at least one radioactivity sensor; determining, by the processor, a sample volume of the aliquot based on a comparison of the sample value of the radioactivity property and the source value of the radioactivity property; determining, by the processor, a pump coefficient based on a comparison of the sample volume with an expected volume, wherein the pump coefficient is configured to indicate a volume of the radiopharmaceutical fluid forced into the fluid delivery channel per unit; and controlling, by the processor, operation of the peristaltic pump to dispense a predetermined dose of the radiopharmaceutical fluid based on the comparison of the sample volume with the expected volume, wherein the sample volume of the aliquot is affected by at least one dimensional property of the fluid delivery channel. - View Dependent Claims (19, 20)
