Wirelessly Powered MRI Signal Amplification System and Method

Description of Technology: The invention is in the field of MRI, and more specifically relates to device and method that may provide great improvements in the area of interventional MRI. The technology describes an MRI detection coil that has been integrated with a parametric amplifier to provide local signal detection fully integrated with amplification. This amplification is done in a way that is inherently wireless, thus enabling efficient signal transmission. The integrated MRI detector/amplifier can be used in a number of applications. First, it can replace conventional MRI amplification typically done with transistor, thus eliminating the need for wires. Second, it can replace what is traditionally used as part of implanted or catheter coils for interventional procedures with MRI. The advantage is that the signal can be amplified, and wireless transmission is part of the amplification scheme. Therefore signal can be transmitted from the subject in a way that provides detection at higher sensitivity than conventional coils without internal amplification.Start Printed Page 44940

Applications: MRI diagnostics and in particular in interventional MRI applications:

  • The device can be used as part of a catheter MRI coil for MRI guided surgery.
  • It can also be used as implantable NMR coils for localized spectroscopy with better sensitivity.
  • The device can potentially be used as a free floating MRI detector/amplifier and swallowed for internal MRI detection as has been done quite successful with optical imaging devices for imaging the human intestine.
  • There may be use in MRI coil arrays where interaction between wires in large element arrays is a problem.


  • The detector/amplifier integrated system eliminates the need for transistors and is wireless, therefore heat is reduced and sensitivity of detection is increased.
  • The system is compatible with interventional MRI devices.

Development Status:

  • Proof of principle has been demonstrated on a prototype device.
  • Testing a second generation device right now with smaller dimension that could be implanted into transplanted organs and used in mm sized catheters for interventional devices or the digestive tract.
  • Plans to develop methods to decouple elements for use in MRI detector arrays.

An Antibody Specific for the Ubl4A Protein

Description of Technology: The antibody developed against the Ubl4A protein is available for licensing. Ubl4A is involved in the proper targeting of tail-anchored proteins to membranes by acting as a chaperone to prevent inappropriate interactions or aggregation. Alterations in membrane insertion or protein degradation may be related to Ubl4a in certain disease states making Ubl4a an attractive biomarker for the study of disease development or as a tool for the development of assays for disease detection.

Applications: The Ubl4a-specific antibody detects Ubl4a in total cell lysates and tissues and can be used to study Ubl4a interactions with other proteins.

The Human Nuclear Co-Repressor Gene: Applications for Cancer Diagnostics/Therapeutics and Gene Expression Research

Description of Technology: The human nuclear receptor co-repressor (huN-CoR) forms multimolecular complexes that alters chromatin structure, resulting in disrupted gene expression. The huN-CoR complex is central to normal processes such as erythropoiesis and thymocyte development, but is also linked to multiple cancers including colorectal carcinomas, endometrial cancers and leukemia, particularly acute myeloid leukemia. Thus, huN-CoR is a potentially-valuable tool for cancer diagnosis, as well as a target for the development of huN-CoR-based cancer therapeutics. HuN-CoR is also an attractive research tool for the study of gene regulation, epigenetic modification and gene silencing.

The technology claims nucleic acid sequences comprising the huN-CoR gene and fragments thereof, as well as a gene chip array incorporating such fragments.


  • Target for novel anti-cancer therapies.
  • Use as a tool for prognosis and diagnosis of HuN-Cor-related diseases.
  • Use as a target for antibody production and development of biological assays to diagnose human disease related to HuN-CoR.
  • Target for rational drug design of novel agents to reverse transcriptional repression
  • Study of molecular repression of targeted genes using HuN-Cor fusion proteins.
