ABSTRACT:
A system and method are disclosed for internally administering a medicinal agent to a patient under the automatic control of a computer. A diagnostic imaging modality, such as a CAT or MRI scanning system, generates one or more images of the patient's anatomy showing a diseased area such as a tumor to which it is desired to deliver the medicinal agent by injection. For each such image, location coordinates with respect to a patient support structure are calculated by the computer for each individual pixel making up the image. Location coordinates are then defined for a select body region corresponding to pixels of the anatomical image(s) designated by a user of the system to receive the medicinal agent. The computer then operates a manipulator arm in order to position an injection needle mounted on the arm adjacent to the select body region and insert the needle into the region at the appropriate depth. An injector is then operated under computer control to force a predetermined amount of the medicinal agent out of a conduit within the injection needle and into the select body region.
