20100296714, Nov 25, 2010

Filed:

May 22, 2008

Appl. No.:

12/601241

Inventors:

Kathleen Schmainda - Elm Grove WI, US
Eric S. Paulson - Wauwatosa WI, US
Douglas E. Prah - Muskego WI, US

Assignee:

IMAGING BIOMETRICS, LLC - Elm Grove WI

International Classification:

G06K 9/00

US Classification:

382131

Abstract:

A magnetic resonance imaging (MRI) methodology is provided for simultaneous measurement of dynamic susceptibility contrast (DSC) MRI and dynamic contrast enhanced (DCE) MRI perfusion and permeability parameters using a combination of dual echo and spiral acquisition techniques with no contrast agent preload. T1 and T2/T2* leakage effects are eliminated, thereby permitting accurate measurement of blood volume, blood flow and vascular permeability which are used in evaluating tumor angiogenesis.

International Classification:

A61B 5/055

US Classification:

600410

Abstract:

An improved method for detecting tumor cell invasion using diffusion times as short as two (2) msec incorporates diffusion weighing imaging techniques into a standard spin echo (SE) pulse sequence to minimize the effects of compartment boundary restrictions on diffusion values and corresponding MRI imaging data related to glioma invasion.

International Classification:

A47C 7/62

US Classification:

2972171

Abstract:

The present invention is an infant stimulation device to be used by a caregiver sitting in a chair and cradling an infant against the caregiver's chest. It is comprised of several strips of fabric with different patterns and textures sewn together at their edges. It has narrowed ends that can fit between the arms or slats of a chair, and the narrowed ends are padded to provide lumbar support for the sitting caregiver. The different patterns and textures of the fabric are designed to stimulate the infant by providing visual and textural contrasts. This encourages the infant to lift and turn his head, and reach out with his hands, stimulating necessary motor development.

Abstract:

Systems and methods for providing image guidance for motion tracking and compensation in magnetic resonance imaging (“MRI”) guided therapies, such as MRI-guided radiation therapies using an MR-linac or other MRI-guided radiation therapy system, are described. Simultaneous orthogonal plane imaging (“SOPI”) is used to acquire images from a first slice that remains static throughout the acquisition, and from a plurality of slices that are orthogonal to the first slice. This first slice can be referred to in some instances as a “tracking” or “navigator” slice, and the plurality of slices that are orthogonal to the first slice can be referred to as “imaging” slices. The tracking slice images can be used to estimate motion of the subject that occurred during the data acquisition, and to track the position of targets (e.g., anatomical targets) during the delivery of radiation treatment.

Abstract:

Systems and methods directed to adaptive radiotherapy planning are provided. In some aspects, provided system and method include producing synthetic images from magnetic resonance data using relaxometry maps. The method includes applying corrections to the data and generating relaxometry maps therefrom. In other aspects, a method for adapting a radiotherapy plan is provided. The method includes determining an objective function based on dose gradients from an initial dose distribution, and generating an optimized plan based on updated images, using aperture morphing and gradient maintenance algorithms without need for organ-at-risk contouring. In yet other aspects, a method for obtaining 4D MR imaging using a temporal reshuffling of data acquired during normal breathing, a method for deformable image registration using a sequentially applied semi-physical model regularization method for multimodality images, and a method to generate 4D plans using an aperture morphing algorithm based on 4D CT or 4D MR imaging are provided.

Abstract:

Systems and methods for designing and fabricating three-dimensional objects with precisely computed material compositions for use in enhancing electromagnetic fields for magnetic resonance imaging (“MRI”) are provided. As examples, the fabricated object can be designed to reduce magnetic field inhomogeneities in the main magnetic field of an MRI system, or to reduce inhomogeneities in a transmit radio frequency (“RF”) field (i.e., a Bfield). As examples, the object can be a shim; a housing or other part of an RF coil; a medical device, such as a surgical implant; or component used in a medical device, such as a housing for an implantable medical device.
