Method for Generating Image Data

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

This patent describes a method and apparatus for generating image data of a moving object inside a body, such as an organ or a fetus. It works by collecting raw data at different times, assessing how the position of the subject changes over time, and then selectively using portions of the data based on their reliability to reconstruct clearer images.

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

• Medical imaging of moving organs, such as the heart or lungs
• Imaging of fetuses during pregnancy
• Assessment of moving tumors or other dynamic structures in the body
• Guiding interventions or surgeries where organ movement is a factor
• Improving image quality in MRI or CT scans with patient movement

BenefitsContent extracted from patent full text and abstract with AI.

• Improved image quality despite subject movement
• Reduced motion artifacts in medical images
• More reliable diagnosis based on better-quality images
• Potential reduction in the need for repeat scans due to movement
• Increased confidence for clinicians in interpreting moving body structures

Patent Abstract

In a method and apparatus for the generation of image data of a moving subject inside a body, raw data are initially acquired for a region encompassing the subject at different measurement points in time, and position overview data for the different measurement points in time are generated on the basis of at least a portion of the raw data. A scattering of the position overview data is then determined, which scattering is dependent on the measurement point in time. Spatial test regions within the position overview data are selected depending on the scattering. Trust parameter values are determined for the individual test regions, and a reconstruction of image data then takes place on the basis of the raw data under consideration of the trust parameter values of the different test regions.
