Method for Acquiring a Magnetic Resonance Data Set by Radial Sampling and Magnetic Resonance Device

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

This invention describes a method and apparatus for acquiring magnetic resonance (MR) data using a radial scanning strategy tailored for non-circular imaging regions. It adjusts the conventional radial sampling order (using angles in k-space) based on the actual shape of the area being imaged, employing an ordering that optimizes the spatial distribution of scans using principles similar to the golden angle method.

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

• Advanced MRI scans for anatomically irregular areas (like the heart, organs, or masses)
• High-resolution MR imaging in medical diagnostics
• Dynamic MR imaging where the shape of the acquisition area changes during the scan
• Preclinical or research imaging of non-circular samples (e.g., tissue cultures, animal models)

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces imaging artifacts for non-circular body regions
• Provides more uniform coverage of the desired imaging area
• Improves image quality and diagnostic accuracy
• Can accommodate both standard and irregularly-shaped scan regions without hardware changes
• Potentially enables faster or more efficient MRI protocols

Patent Abstract

Method to acquire a magnetic resonance data set of an acquisition area (5) in a subject (O) via radial scanning along a fixed number of spokes (6) respectively described by a first angle in k-space, wherein the acquisition area (5) deviates in positional space from a circular shape in a shape that can be described by the set of first angles; wherein the acquisition of the spokes (6) takes place according to an acquisition order; wherein an acquisition position of the acquisition order is associated with each first angle under consideration of a comparison data set of the fixed number of second angles (in which second angles of successive acquisition positions differ by a golden angle) such that, for a first angle of each acquisition position, the spatially adjacent first angles have the same acquisition positions as the second angles spatially adjacent to a second angle of the acquisition position.
