Novelty:
A device to maximize cancellation of the magnetic field distortion created when objects with high variations in magnetic susceptibility are placed in a uniform magnetic field; specifically, this device facilitates the reduction of MR imaging artifact produced by pacemakers and ICDs in order to maximize the diagnostic image quality in the region surrounding to these devices.
Value Proposition:
MRI is the gold-standard modality for localizing myocardial scar; however, significant MR image distortion and signal loss can result with the introduction of pacemakers and ICDs to the imaging field. Despite the increasing patient population with pacemakers and ICDs, there is currently no known method that will cancel the associated large susceptibility artifacts. This device minimizes larger magnetic field distortion than is possible with currently available solutions. Other advantages include:
Technical Details:
Johns Hopkins researchers have developed a technology that minimizes MR imaging artifact produced by objects with high variations in magnetic susceptibility. This technology produces a controlled field distortion that opposes the field distortion created by an artifact-producing object such that the superposition of the two field distortions can reduce the net field distortion. The technology consists of a solenoid electromagnet positioned adjacent to an artifact-producing object and a computing device configured to optimize artifact reduction. The computing device alters the intensity and polarity of the solenoid electromagnet field distortion by adjusting its current source and position.
Looking for Partners:
To develop and commercialize technology as a stand-alone or incorporated device for use with new or existing MR imaging systems.
Stage of Development:
