Signal-to-Noise Enhancement in Imaging Applications Using a Time-Series 
of Images

    Description of Invention: The invention offered for licensing 
relates to the field of imaging and specifically to the field of 
medical imaging. The apparatus and method of the invention provide for 
noise reduction in imaging applications that use a time-series of 
images. In one embodiment of the invention, a time-series of images is 
acquired using a same imaging protocol of the same subject area, but 
the images are spaced in time by one or more time intervals (e.g. 1, 2, 
3 * * * seconds apart). A sub-region is projected across

[[Page 4571]]

all of the images to perform a localized analysis (corresponding X-Y 
pixels or X-Y-Z voxels are analyzed across all images) that identifies 
temporal components within each sub-region. Subsequently, within the 
sub-regions, only those temporal components are selected whose 
amplitude is above a predetermined amplitude threshold. The images are 
then reconstructed using the sub-regions with reduced components. A 
maximal-intensity-projection (MIP) is applied in the temporal domain 
(tMIP) in order to obtain a single image with reduced noise (this can 
be done either at the sub-region level or at the reconstructed image 
level). The technology can be applied to a broad spectrum of medical 
imaging technologies such as MRI, X-Ray, CT and others.
    Applications: Medical imaging and diagnostics applied to MRI, X-
Ray, CT scans or other imaging modalities including PET, SPECT, 
ultrasound or optical.
    Advantages: Enhancing signal-to-noise of medical imaging 
techniques.
    Development Status:
     Proof of concept has been demonstrated. Data is available.
     Need to acquire further data to establish clinical utility 
of the method and to further optimize the protocol.
    Market:
     According to market research reports the market for 
medical imaging equipment industry in the United States is 
approximately $9.0 billion dollars now and has been growing by 
approximately 7.6% annually.
     The United States market for computed tomography (CT) 
scanning systems is estimated to touch $3.6 billion by the end of 2009. 
The U.S. accounts for over 50.0% of the worldwide market.
     Worldwide MRI equipment market is estimated to reach $5.5 
billion by 2010, according to new report by Global Industry Analysts, 
Inc. (http://www.strategyr.com/Magnetic_Resonance_Imaging_MRI_Equipment_Market_Report.asp). In the United States the market for 
such equipment is estimated at $1.9 billion for 2008, as stated the 
same report. The very high-field MRI systems market in the United 
States is projected to reach $968 million by the year 2010. Very High-
Field Systems also represent the fastest growing segment, as hospitals 
and clinics upgrade old equipment with state-of-the-art systems.
     Enhancements in imaging technologies to achieve better 
image clarity, reliability and speed are being constantly pursued by 
medical imaging companies. Technologies that offer such improvements 
therefore present excellent commercial potential. Thus the subject 
invention which can be applied in a broad spectrum of imaging 
technologies offers such good commercial potential.

Method for the Treatment of HIV/AIDS Infection Using Acyclovir in 
Identified Subjects

    Description of Invention: The invention provides the novel method 
to treat HIV infections with acyclovir which can be converted to 
acyclovir triphosphate inside infected cells. Acyclovir or acyclovir-
related drugs were previously approved for control of herpesvirus 
replication with 20 years of records of safe application. The subject 
invention demonstrates that acyclovir triphosphate can inhibit HIV-1 
reverse transcriptase as a potent suppressor of HIV-1 replication in 
human lymphoid tissues. In addition, the subject invention may be 
attractive to potential licensees, as there is little to no FDA hurdle 
to overcome in the development of the new formulations to use in this 
manner. Thus, the low cost and proven safety of acyclovir may lead to a 
new medicine for treating HIV-1 infections and a prophylactic agent for 
preventing HIV infections.
    Applications: The treatment and prevention of HIV infections.
    Development Status: In vitro data available.
    Inventors: Leonid B. Margolis, Andrea Lisco, Christophe Vanpouille, 
Jean-Charles Grivel (NICHD).
