Acquisition of Magnetic Resonance Data at the Edge of the Field of View of a Magnetic Resonance System

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

This patent describes a method for improving the capture of magnetic resonance (MR) imaging data at the outer edges (periphery) of the scanner’s field of view. It uses a specially adapted gradient field to compensate for magnetic field inconsistencies at the edges and involves repositioning the object to be examined so that all relevant layers are accurately scanned.

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

• Medical imaging for diagnosing conditions located at the edges of scanned organs or body parts
• Research studies requiring full coverage of complex or irregularly-shaped anatomical structures
• High-precision MR imaging in neurological, orthopedic, or oncological applications where peripheral data is critical

BenefitsContent extracted from patent full text and abstract with AI.

• Improved image quality and accuracy at the edges of the MRI scanner's field of view
• Enhanced diagnostic capability by reducing artifacts and errors in peripheral regions
• Allows examination of larger or non-central body regions that might have been inadequately scanned before
• Greater flexibility for scanning various patient sizes and positions

Patent Abstract

A method is disclosed for acquiring magnetic resonance (MR) data for a plurality of layers of an object to be examined in a section of a magnetic resonance system having a basic magnetic field, wherein the section is located at the edge of a Field of View of the magnetic resonance system in the first direction. The method includes producing a first gradient field having a non-linearity of its location dependence in such a way that in the section the non-linearity compensates a local inhomogeneity of the basic magnetic field, and then multiple positioning of the object to be examined in a first direction, so the plurality of layers of the object to be examined perpendicular to the first direction successively includes the section. Finally, it includes the acquisition of magnetic resonance data for each of the layers with recording sequences.
