A motor for use in magnetic fields generated for medical imaging. The motor comprises a stator. The stator includes a piezoelectric material and is configured to generate vibrations when subjected to a voltage gradient. A rotor is arranged and configured so that vibrations generated in the stator will propel the rotor. A drive shaft is connected to the rotor. The rotor and drive shaft are formed from a material that has a magnetic susceptibility that is about the same as the magnetic susceptibility of water.

Piezoelectric motor for use in magnetic fields

The invention provides a robot hand that can mimic the movements of a human hand in operation. The robot hand includes a thumb and at least one opposing finger having at least two phalanxes connectable to each other by a distal phalanx joint. The thumb of the robot hand also includes a joint which allows the thumb to move transversely with respect to the opposing fingers. The robot hand can also include one or more additional fingers disposed on an opposite side of the thumb. The robot hand can be operated mechanically or electrically through controlling motors.

Robot hand

The present invention provides materials and methods for preparing medical instruments which cause reduced or enhanced artifact on diagnostic images. According to the invention, a reduced artifact instrument may be prepared using titanium alloy compositions or plastic compositions disclosed herein. An enhanced artifact instrument may be prepared by incorporating artifact causing materials into artifact free instruments. Such instruments are suitable for use during diagnostic imaging procedures, for example, magnetic resonance imaging. The invention also provides compositions and methods for removing magnetic contaminants from the surface of a medical instrument or an alloy material.

Controlled-artifact magnetic resonance instruments

The invention provides a device for correlating the internal location of an anatomical point of a human or animal patient with a location on the external body contours of the patient. In one embodiment, the invention is particularly suited for external positioning of a medical instrument for insertion into the patient's body to contact the anatomical point
