1. An imaging-guided injection system for delivering an anesthetic to a target anatomical location of a patient, the system comprising:

  • a fluid delivery module comprising at least one loading area configured to receive a container comprising an anesthetic, the at least one loading area being configured to securely receive various sizes and shapes of the container;

    at least one fluid reservoir within an interior of the fluid delivery module;

    at least one fluid conduit configured to be placed in fluid communication with the at least one fluid reservoir, said at least one fluid conduit comprising a distal end, said distal end configured to receive a needle;

    wherein the fluid delivery module is configured to selectively transfer at least a portion of the anesthetic from the container to the at least one fluid conduit via the at least one fluid reservoir;

    wherein the fluid delivery module comprises at least one motor, said at least one motor being configured to facilitate the transfer of the anesthetic to the at least one fluid conduit;

    at least one controller configured to regulate at least one aspect of the delivery of the anesthetic from the fluid delivery module to the target anatomical location of the patient according to a delivery scheme; and

    wherein the system is configured to be placed in data communication with an imaging device to assist in accurately advancing the needle into the anatomy of the patient;

    a display providing (i) status information related to the delivery of the anesthetic to the target anatomical location, and (ii) at least one real-time image obtained by an imaging device;

    wherein the status information comprises at least one of;

    (i) a volume of fluid delivered from the at least one fluid reservoir to the handpiece assembly, and (ii) a volume remaining in the at least one fluid reservoir of the fluid delivery module;

    wherein the system is configured to be placed in data communication with an imaging device to assist in accurately advancing the stimulation needle into the anatomy of the patient;

    wherein the display is additionally configured to provide at least one real-time image obtained by the imaging device; and

    wherein the system is configured to detect a back-pressure associated with a delivery of the anesthetic through the at least one fluid conduit.
