Filed:

May 16, 2002

Appl. No.:

10/063826

Inventors:

Paul E. Licato - Wauwatosa WI, US
Steven Wolff - New York NY, US

Assignee:

GE Medical Systems Global Technology Company, LLC - Waukesha WI

International Classification:

A61B 5/05

US Classification:

600410, 324306, 324307, 324309

Abstract:

Disclosed herein is a system and method for decreasing gradient field pulse sequence duration and reducing peripheral nerve stimulation with known gradient pulse areas for a magnetic resonance imaging system. The method comprising: receiving a first desired area corresponding to a first pulse; obtaining a second desired area corresponding to a second pulse; selecting the first pulse as a nested pulse if the first desired area is smaller than the second desired area, and establishing the second pulse as a nesting pulse, otherwise selecting the second pulse as the nested pulse and establishing the first pulse as the nesting pulse. The method also includes: determining an amplitude and pulse duration for the nested pulse and ascertaining an amplitude and pulse duration for the nesting pulse. Finally, the method includes arranging a plurality of gradient field pulse sequences to include the nested pulse and the nesting pulse.

Abstract:

The present invention discloses a modular MRI imaging system. The imaging system includes MRI radio-frequency antenna arrays separate from the patient support structure. The antenna arrays are affixed to a thin, flexible film such that they may be located next to the anatomical region of interest. In addition, multiple antenna arrays may be configured in various planar or three-dimensional arrangements to optimize the FOV and SNR. Separate patient support structures are provided that enhance ergonomics and patient stabilization. By removing the antenna from the housing, the support structures may be designed without the constraints of supporting the antenna or the associated electronics. The MRI imaging system further employs a preamplifier module. The preamplifier module houses the preamplifier and much of the other associated circuitry for each of the antennae. The preamplifier module operates to combine the signals from the antenna arrays and pass the signals to the MRI system.

Abstract:

A system for automatically identifying a needle insertion location from a medical diagnostic image, such as an MRI image, and providing a visual indication of the needle insertion location is disclosed. A grid plate is located proximate to an anatomical region and is preferably incorporated in an MRI support structure utilized to immobilize the anatomical region. An MRI scanner obtains an MRI image of the anatomical region, and an MRI technician places a marker on the MRI image, identifying the needle insertion location. The MRI image and the marker are transferred from the MRI scanner to another device, such as a tablet computer, which is configured to convert the MRI image and the marker to coordinates and an insertion depth. A visual indicator is located proximate to or integrated with the grid plate that provides the needle insertion coordinates and insertion depth to the MRI technician.
