Filed:

Oct 10, 2008

Appl. No.:

12/249652

Inventors:

John Christopher Rauch - Savoy IL, US

Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA

International Classification:

A61B 6/03

US Classification:

378 4, 378210, 378901, 382131

Abstract:

A method and system provides medical image processing and 3-dimensional image construction of an examination subject. A user is enabled to selectively orient an x-ray imaging system having a variable 3-dimensional acquisition axis relative to an examination subject support for holding an examination subject. A non-planar image data acquisition path is set for the x-ray imaging system oriented around the variable 3-dimensional acquisition axis in response to user instruction. Acquisition of image data of the examination subject is initiated by the x-ray imaging system at a plurality of points along the non-planar image data acquisition path. A 3-dimensional image is constructed from the acquired image data such that any metal artifacts introduced by radio-opaque objects within the examination subject are minimized. The 3-dimensional image is displayed.

International Classification:

G06K 9/00
A61B 6/00
A61K 49/04

US Classification:

382130, 378 4, 424 94

Abstract:

A system automatically processes different medical image sequences facilitating comparison of the sequences in adjacent respective display areas. An image data processor, identifies first and second mask images of first and second image sequences respectively as images preceding introduction of contrast agent and determines a translational shift between the first and second mask images. The image data processor transforms data representing individual images of at least one of the first image sequence and the second image sequence in response to the determined translational shift to reduce mis-alignment of the individual images of the first image sequence relative to the individual images of the second image sequence. A display presents first and second image sequences corrected for mis-alignment, in substantially adjacent display areas to facilitate user comparison.

International Classification:

G06K 9/00
A61B 6/00

US Classification:

382131, 382221, 378 21

Abstract:

A motion compensated digitally subtracted Angiography (DSA) image processing system includes an interface for acquiring a sequence of images of patient vessels both prior to and following introduction of contrast agent into the vessels. An image data processor automatically, (a) determines a first shift vector for a first image of the sequence for compensating for shift between the first image and a first reference image of the sequence, (b) applies the determined first shift vector to the first image of the sequence to produce a shifted image, (c) subtracts the first reference image from the shifted image to produce a subtracted image enhancing vessel structure, (d) determines a second shift vector for compensating for shift between the subtracted image and a second reference image and (e) shifts content of the subtracted image relative to the second reference image in response to the second shift vector, to provide a shifted subtracted image enhancing and aligning vessel structure.

Inventors:

John C. Rauch - Savoy IL, US

International Classification:

A61B 5/05

US Classification:

600426

Abstract:

A system and method of producing virtual roadmap image of a patient is described. CT-like image data may be obtained for a patient, with or without a contrast agent, and differenced so as to form a roadmap mask. The roadmap mask is in the form of a 2-dimensional digitally reconstructed radiograph from the same orientation as that of a fluoroscopic X-ray device which takes real-time images of the patient during treatment. The fluoroscopic image may be subtracted from the roadmap mask so as to more clearly visualize the position of a catheter introduced into the patient for treatment. When the orientation of the fluoroscopic image is changed during the course of treatment, the roadmap mask image for the corresponding orientation is used.

International Classification:

A61B 5/00

US Classification:

600300, 382128

Abstract:

A workflow for a minimally invasive intervention, such as a treatment for a cancerous tumor, includes positioning a patient at a multi-functional imaging apparatus, obtaining pre-interventional images of the anatomy of the patient using a computed tomography or angiography imaging function, performing the minimally invasive intervention while the patient is positioned at the multi-functional imaging apparatus and while using a fluoroscopic imaging function, and performing a post-interventional imaging of the patient's anatomy while the patient is positioned at the multi-functional imaging apparatus using the computed tomography or angiographic imaging function. If the post-interventional imaging determines that additional intervention is in order, the additional intervention is performed while the patient is positioned at the imaging apparatus. Pre-intervention images and data sets from other sources may be combined with or used during the intervention. A treatment planning step may be included following the pre-interventional imaging and the intervention.

International Classification:

G06K 9/00

US Classification:

382132

Abstract:

In a method for acquiring a 3D image rotational acquisition and reconstructed 3D image of an examination subject in whom a highly dense object is located, the 3D acquisition axis for acquiring the 3D image rotational acquisition is selected prior to acquisition, such that the orientation of the region of interest with respect to an artifact inducing object is not perpendicular to the 3D acquisition axis.

International Classification:

G09G 5/00
A61B 6/00

US Classification:

345619, 600431

Abstract:

A system creates a visually (e.g., color) coded 3D image that depicts 3D vascular function information including transit time of blood flow through the anatomy. A system combines 3D medical image data with vessel blood flow information. The system uses at least one repository for storing, 3D image data representing a 3D imaging volume including vessels, in the presence of a contrast agent and 2D image data representing a 2D X-ray image through the imaging volume in the presence of a contrast agent. An image data processor uses the 3D image data and the 2D image data in deriving blood flow related information for the vessels. A display processor provides data representing a composite single displayed image including a vessel structure provided by the 3D image data and the derived blood flow related information.

International Classification:

G06K 9/00

US Classification:

382131

Abstract:

A method generates a two dimensional (2D) medical image through a three dimensional (3D) imaged volume of patient anatomy at a desired position, by storing 3D image data representing a 3D imaging volume including vessels in the presence of a contrast agent. The 3D image data comprises, data identifying multiple voxels representing multiple individual volume image element luminance values and luminance distribution data for individual voxels of a vessel in the 3D image data. For multiple individual voxels of a 2D image, the method determines composite luminance distribution data of an individual voxel in the 2D image by combining luminance distribution data of the 3D image data of multiple identified voxels substantially lying on a projection line from a source point to the individual voxel and generating data representing the 2D image using the determined composite luminance distribution data of the multiple individual voxels.
