System and Method for Automatic Speed Adaptation Control of a Treadmill

    Description of Invention: The invention offered for further 
commercial development relates to the coupling of virtual reality 
technology with a treadmill to implement goal-oriented walking 
practices effectively and to promote improved learning skills during 
gait training. The technology will be useful in rehabilitation of 
individuals with gait impairments resulting from Parkinson's disease, 
Traumatic Brain Injury, Stroke, Cerebral Palsy, and Spinal Cord Injury. 
In order to allow patients practice (e.g., voluntary change of walking 
speed in a natural way), software has been developed that automatically 
updates the velocity of a treadmill following the intention of the 
person walking on the treadmill. The invention uses a swing foot 
velocity measurement to control the velocity of the treadmill which can 
quickly and precisely detect the user's intention of changing walking 
velocity. Swing foot velocity measurement allows users to voluntarily 
change walking velocity while they have a realistic feel of walking 
(such as over-ground walking). We are seeking a CRADA collaborator to 
expand implementation of the invention into a fully integrated system 
that can control treadmill velocity in real time and can be reliably 
adapted to typical commercial treadmills.
    Applications:
    <bullet> Rehabilitation of individuals with gait impairments as a 
complication of Parkinson's disease, traumatic brain injury, stroke, 
cerebral palsy, or spinal cord injury.
    <bullet> The technology can also be used for walking through 
architectural models, for educational purposes (student walk through 
historical sites or geological surfaces), military or law enforcement 
training, gaming, motor and sensory rehabilitation, and exercise and 
recreation.
    Development Status: Development partner with experience designing 
virtual reality environments is sought for a CRADA collaboration.
    Inventors: Hyung S. Park (NIH/CC) and Jung Won Yoon.

Hematoma Detector and Discriminator

    Description of Invention: The invention offered for licensing and 
further development is a device and method for detecting hematomas. The 
device is based on near infrared light emitted perpendicularly into a 
tissue from a non-stationary emitter and on continuous detection of the 
reflected light with a non-stationary probe. The device is designed as 
a handheld detector that can be used either in an ER or at the scene of 
an accident, which will allow the Doctor or EMT to diagnose hematoma 
for patients with a Traumatic Brain Injury at the scene. Furthermore, 
this device can be utilized to discriminate between subdural and 
epidural hematoma. The invention also discloses a novel method of data 
analysis. The specific combination and sequences of data analysis are 
performed to discriminate healthy tissue from tissue perfused with 
blood. In addition, an interface to a laptop will be provided that 
creates a 3D surface image of the location of the hematoma is 
displayed. This invention will result in a better triage and treatment 
for patients with Traumatic Brain Injury (TBI) and fills a must filled 
gap in TBI health care.

    <bullet> Diagnosis for hematoma
    <bullet> Early screening and triage for diagnosis of hemorrhage 
from head trauma

System and Method for Monitoring and Controlling Radio Frequency 
Signals in Interventional Devices

    Description of Invention: The invention offered for licensing and 
commercial development is in the field of Interventional Magnetic 
Resonance Imaging (``iMRI''). More specifically the invention discloses 
interventional devices in which the heat generated at the device during 
the imaging process can be controlled to not exceed acceptable levels.
    Interventional devices may heat up significantly during an 
interventional MRI procedure as a result of an RF induced current on 
the device. The RF induced current is caused by the coupling between 
the interventional device and RF electrical fields generated by the 
MRI. As the magnitude of the induced RF signal increases, the amount of 
heat that is generated also increases. The system of the present 
invention measures the induced RF signal and changes a decoupling 
capacitor value by using a varactor and a control circuit to adjust the 
impedance of the device and thus controls the magnitude of the RF 
signal. This unique design renders the device and the procedures done 
with it safe.
    Applications:
    <bullet> Interventional cardiology
    <bullet> MRI guided surgery
    Advantages: The device may fundamentally enable any ``active'' MRI 
catheter device to be safe during real-time MRI guided interventional 
procedures. Automated feedback loops between RF power applied by the 
MRI scanner and measured power detected inside the MRI catheter coil 
can be used to assure safety of ``active'' MRI catheter devices.
    Development Status: In development. Prototype is being built.

Single Channel MRI Guidewire

    Description of Invention: The invention offered for licensing and 
commercial development is in the field of Interventional Magnetic 
Resonance Imaging (``iMRI''). More specifically the invention discloses 
a guidewire for magnetic resonance imaging with a single channel design 
to reduce complexity and to provide conspicuous tip visibility under 
MRI. In the design of the present device, the guidewire body includes 
an antenna formed from a rod and a helical coil coupled together. The 
helical coil can have multiple windings without a gap between the 
windings. The rod passes through the windings of the helical coil and 
is coupled to the helical coil using a conductive joint positioned at 
an end of the rod and at an end of the helical coil. Insulation can be 
positioned between the rod and the windings of the helical coil. The 
configuration allows visibility of the antenna along the length of a 
rod, except where it enters the windings of the coil. Thus, the tip 
visibility is enhanced as being separated from the rod.
    Applications:
    <bullet> Interventional cardiology
    <bullet> MRI guided surgery
    Advantages:
    <bullet> The unique design of the device and its dipole antenna, 
provide a lower profile guidewire (such as coronary 0.014: guidewire) 
and it is therefore safer and more convenient to use compared with 
existing guidewires.
    <bullet> The modified dipole antenna of the device can combine the 
distinct tip signal profile typical of loop antennae with the whole-
shaft visibility of dipole antennae, all operating on a single receiver 
channel. This overcomes challenges both of conspicuity and of 
undesirable coupling of comparable two-channel devices that causes 
heating.
    Development Status: In development. Prototype is being built.

Active Adaptive Detuning Systems To Improve Safety of Interventional 
Devices

    Description of Invention: The invention offered for licensing and 
commercial development is in the field of Interventional Magnetic 
Resonance Imaging (``iMRI''). More specifically the invention discloses 
interventional devices in which the heat generated at the device during 
the imaging process can be controlled to not exceed acceptable levels.
    Active MRI compatible intravascular devices contain RF antenna so 
that they are visible under MRI. However, these metallic structures may 
heat up significantly during interventional MRI procedures due to eddy 
current formation over the conductive transmission lines. The 
electrical field coupling between interventional devices and RF 
transmission coils strongly depend on the device position and 
orientation within the bore and insertion length of the device. 
Currently, conventional detuning circuit is used to decouple the 
conductive intravascular device during RF transmission phase of the MRI 
by activating the circuit with a PIN diode. However, conventional 
passive techniques do not adapt for each possible orientation or 
insertion length of the device. The current invention provides for a 
new active detuning system that adapts its circuit component to limit 
heating for every possible orientation and insertion length. The system 
reads out the received current signal value during RF transmission 
phase and changes the decoupling capacitor value by using varactor and 
integrated circuit components to reach new resonant condition (very 
high impedance).
    Applications:
    <bullet> Interventional cardiology
    <bullet> MRI guided surgery
    Advantages: The device may fundamentally enable any ``active'' MRI 
catheter device (independent of the orientation and insertion length of 
the device) to be safe during real-time MRI guided interventional 
procedures.
    Development Status: In development. Prototype is being built.
