Method and apparatus for injecting a substance into the bloodstream of a subject
Abstract
An apparatus and method for injecting a substance, such as a radiopharmaceutical, into the bloodstream of a subject. The apparatus comprises an injection means, such as a servo controlled syringe, a means for measuring the concentration of that substance in the subject's bloodstream, and means for controlling the injection in response to the measurement so that the concentration of the substance follows a predetermined function of time. The apparatus of the subject invention functions to inject a substance into a subject's bloodstream at a rate controlled by an error signal proportional to the difference between the concentration of the substance in the subject's bloodstream and the predetermined function.
