Abstract:

In one embodiment, a method of detecting centerline of a vessel is provided. The method comprises steps of acquiring a 3D image volume, initializing a centerline, initializing a Kalman filter, predicting a next center point using the Kalman filter, checking validity of the prediction made using the Kalman filter, performing template matching, updating the Kalman filter based on the template matching and repeating the steps of predicting, checking, performing and updating for a predetermined number of times. Methods of automatic vessel segmentation and temporal tracking of the segmented vessel is further described with reference to the method of detecting centerline.

Appl. No.:

11/614593

Inventors:

Glenn Scott Slavin - Silver Spring MD, US
Sandeep Narendra Gupta - Hanover MD, US

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:

G06K 9/36

US Classification:

382291

Abstract:

A method of determining an anatomically consistent scan protocol for an object of interest includes obtaining a volumetric image of an object of interest to be imaged, transforming the volumetric image, estimating the position and orientation of the object using the volumetric image and the transformed volumetric image, and modifying the imaging scan protocol using the estimated object position and orientation.

International Classification:

A61B 5/055

US Classification:

600410

Abstract:

A method for motion compensation includes acquiring an initial volumetric localizer to establish an initial object position and initial object orientation at an initial state, acquiring a fast localizer of the object at a present state, aligning the fast localizer to the initial volumetric localizers to determine object motion between the initial state and the present state, and modifying an imaging protocol using the object position and orientation at the present state.

International Classification:

G06K 9/00
G01R 33/48

US Classification:

382131, 324309

Abstract:

A system and method for automatic computation of MR imaging scan parameters include a computer programmed to acquire a first set of MR data from an imaging subject, the first set of MR data comprising a plurality of slices acquired at a first field-of-view. The computer is also programmed to reconstruct the plurality of slices into a plurality of localizer images and identify a 3D object based on the plurality of localizer images. The computer is further programmed to prescribe a scan, execute the prescribed scan to acquire a second set of MR data, and reconstruct the second set of MR data into an image. The prescribed scan includes one of a reduced field-of-view based on a boundary of the 3D object and a shim region based on the boundary of the 3D object.

International Classification:

G06Q 50/24

US Classification:

705 3

Abstract:

An imaging workflow system includes a workstation for acquiring patient information and requesting a patient scan. The request for a patient scan includes scan information for performing the scan. A registration module receives the scan information and the patient information. The registration module automatically schedules the patient scan based on the scan information and the patient information. The registration module determines an imaging protocol based on the patient information and the scan information. An imaging module within an imaging system receives the imaging protocol. The imaging module automatically sets scan parameters based on the imaging protocol. The imaging system scans the patient based on the scan parameters to acquire image data. A user interface controls the patient scan. The user interface includes a display to display images generated from the acquired image data.
