Filed:

Sep 28, 2001

Appl. No.:

09/967297

Inventors:

Sandeep N. Gupta - Baltimore MD
Garth M. Beache - Baltimore MD
Daniel A. Herzka - Silver Spring MD

Assignee:

GE Medical Systems Global Technology Company LLC - Waukesha WI
John Hopkins University - Baltimore MD

International Classification:

A61B 5055

US Classification:

600410, 382294, 382131, 382278

Abstract:

The present invention is a method and apparatus for semi-automatically registering low signal to noise ratio relaxation-time images, with particular application to tracking motion in moving organs and quantifying myocardial perfusion reserve. For each image acquired in a time series, a corresponding high signal to noise ratio image is extrapolated from the collected data. The high signal to noise ratio images are registered to track motion, and the resulting registration data is copied onto the corresponding relaxation time image.

Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY

International Classification:

G01R 33/50
G01R 33/48

US Classification:

324318, 702 19

Abstract:

A method for rapid measurement of T relaxation comprises a gated, multi-time-point saturation-recovery experiment. Each saturation-recovery experiment may include multiple gating intervals to increase dynamic range of the T measurement. Multiple saturation-recovery experiments may also be used to improve accuracy and signal-to-noise of the T measurement.

International Classification:

A61B 5055

US Classification:

600410

Abstract:

The present invention relates to magnetic resonance imaging (MRI) and includes a method and apparatus to track motion of anatomy or medical instruments, for example, between MR images. The invention includes acquiring a time series of MR images of a region of interest, where the region of interest contains the anatomy or structure that is prone to movement, and the MR images contain signal intensity variations. The invention includes identifying a local reference region in the region of interest of a reference image and acquired from the time series. The local reference region of the reference image is compared to that of the other MR images and a translational displacement is determined between the local reference region of the reference image and of another MR image. The translational displacement has signal intensity invariance and can accurately track anatomy motion or the movement of a medical instrument during an invasive procedure. The translational displacement can be used to align the images for automatic registration, such as in myocardial perfusion imaging, MR angiography, fMRI, or in any other procedure in which motion tracking is advantageous.
