Imaging a Partial Region of an Examination Object in a Magnetic Resonance System

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for improving the imaging of a specific part of an object in a magnetic resonance (MR) scanner. It achieves this by manipulating gradient fields so that distortions from field non-linearities and magnetic field inhomogeneities at certain positions cancel each other out, resulting in clearer MR images of the target area.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical imaging in hospitals for more accurate scans of specific body parts
• Research labs needing precise MR images of samples or specific regions of interest
• Clinical diagnosis of diseases affecting localized regions, such as tumors or vascular abnormalities
• High-resolution MR imaging in neuroscience research focusing on particular brain areas

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces image distortions caused by technical limitations of MR gradient fields and magnetic field inhomogeneities
• Improves accuracy and clarity of MR images in targeted regions
• Facilitates better diagnosis by providing more reliable localized images
• Enhances the capability of MR systems to focus on specific anatomical structures or lesions

Patent Abstract

A method is disclosed for imaging a part region of an examination object in a magnetic resonance system. In an embodiment, a first and second gradient field are respectively created such that, at a respective first and second position at the edge of the field of view, a distortion caused by a non-linearity of the respective first and second gradient field, and a distortion caused by a B0 field inhomogeneity, cancel each other out. By way of the respective first and second gradient, respective first and second magnetic resonance data which contains the respective first and second position are acquired. A first and second respective readout direction, in which the respective first and second magnetic resonance data are acquired, are selected as a function of a location of the respective first second position are acquired. From the magnetic resonance data, an image of the part region is defined.
