C01736: Distortion-Free Imaging MotorNovelty:
A new motor designed specifically for medical imaging systems, which does not affect image quality.
Value Proposition:
Many medical imaging methods include motorized elements to control motion or placement of the imaging devices. For modalities such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT), rotational motors are essential to the successful capture of data. However, the electronic components in these motors can cause magnetic or other types of distortions which can be reflected in the data obtained from the patient. This invention provides a new kind of motor which does not cause such distortions, while still providing precise, high torque, backlash-free rotary motion. Other advantages Include:
• Does not run on or use electronic components
• Can be used in both Imaging and Surgical environments
• Motion can be further controlled with external sensors
Technical Details:
Johns Hopkins researchers have developed a pneumatic motor that eliminates the need for distortion-causing electronics in medical imaging applications. By sequentially pressurizing various ports on the motor, rotational motion can be achieved and precisely controlled. The materials used in construction are compatible with all forms of medical imaging, allowing for simple adaptation into existing systems.
Looking for Partners:
To develop and commercialize the technology to replace current motors in any rotary applications within the Medical Imaging Market.
