Abstract: A robotic device for use in conjunction with an imaging system and an imaging method is provided. The robotic device can provide mechanical measurements within the imaging system, and can also control the mechanical environment within the imaging system. An end effector of the robotic device engages a body segment of the patient. In addition, position and force sensors are associated with the robotic device such that the position and forces applied to the end effector can be sensed/measured and recorded, while images are obtained. In addition, the robotic device includes actuators to move the end effector to a desired position, and/or to provide a force to a body segment of a patient by way of the end effector. In a particularly preferred form, structural, sensory, and actuator components of the robotic device are magneto-translucent, such that the robotic device can control and/or provide measured information regarding the mechanical environment within a magnetic resonance imaging system.

Abstract: An interactive robotic therapist interacts with a patient to shape the motor skills of the patient by guiding the patient's limb through a series of desired exercises with a robotic arm. The patient's limb is brought through a full range of motion to rehabilitate multiple muscle groups. A drive system coupled to the robotic arm is controlled by a controller which provides the commands to direct the robotic arm through the series of desired exercises.
