Abstract

A method and apparatus of dispensing a radiopharmaceutical wherein a source of flushing fluid is connected to a first port of a fluid delivery set; a pressurizing unit of a powered injector system (including a powered injector and the pressurizing unit) is connected to a second port of the fluid delivery set; air is purged from the fluid delivery set; and, after purging air from the fluid delivery set, a third port of the fluid delivery set is connected to a source of the radiopharmaceutical. A valve system is included to control flow of fluid. A syringe is operatively connected with a powered injector. A radioactive shield encloses the syringe during operation to protect personnel from detrimental effects. A dose calibrator measure the radioactivity in the syringe.

Claims

1. A shield for use with a radiopharmaceutical, the shield including a housing that is impenetrable by radioactive energy from the radiopharmaceutical, the shield also including at least one opening in the housing through which an article containing the radiopharmaceutical and positioned within the housing can be viewed, the opening being in visual alignment with a reflective surface in which a viewer can view a reflection of the article, the opening being positioned within the housing such that there is no direct line between the viewer and the article that is not shielded by a portion of the housing.
