1. A system for delivering a therapeutic agent to a patient comprising:

  • a computer;

    an injection needle device for delivering a fluid agent into a tissue;

    an automatic manipulator including a manipulator arm assembly for supporting and operation said injection needle and a power driving device for moving said manipulator arm along multiple axes;

    a patient support structure having a support surface;

    a power driven device operable under computer control for moving said support surface and said manipulator arm assembly relative to one another to cause the manipulator arm assembly to controllably move said injection needle into select regions of the patient'"'"'s body;

    a scanning system including an imaging device for generating image information of select anatomical regions of the patient'"'"'s body wherein said imaging device includes an ultrasonic pulse-echo transducing means and an actuator for effecting relative movement between said patient support surface and said imaging device which includes a manipulator arm assembly for positioning said ultrasonic transducer under control of said computer;

    a plurality of sensors for sensing the relative positions of said patient support, said manipulator arm assembly, and said scanning imaging device, and generating and feeding coded signals representing the sensed positions to said computer;

    a first computer program for calculating location coordinates of select body regions defined by pixels of images produced by said scanning imaging device and using the coded signals representing the sensed relative positions of said patient support means and said imaging device; and

    a second computer program for calculating location coordinates of said injection needle and determining when said injection needle is located at said select body region into which it is desired to deliver a therapeutic agent.
