Method for Generating Motion Correction for PET Data, Method for Generating PET Images, and Correspondingly Configured MR System and PET System

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

This invention describes a method for improving PET (Positron Emission Tomography) imaging by correcting for motion in the patient during the scan. It uses MR (Magnetic Resonance) data to build a motion model. This model enables accurate correction of the PET data depending on the detected motion, leading to clearer and more reliable PET images.

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

• Medical imaging in oncology for cancer detection and monitoring using PET/MR systems.
• Cardiac imaging, where heart or respiratory movement affects the accuracy of PET scans.
• Neurological studies where patient movement can blur PET imaging results.
• Combined MR-PET scanning procedures in hospitals and diagnostic centers.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved clarity and accuracy of PET images by correcting for patient motion.
• Enhanced diagnostic confidence for medical professionals due to better quality images.
• Reduction in the need for repeat scans, saving time and resources.
• Applicability in hybrid imaging systems (PET/MR), helping integrate and cross-utilize data from different imaging modalities.

Patent Abstract

A method is disclosed for creating a motion correction for PET data acquired by a PET system from a volume segment of an examination object. The method includes acquisition of MR data within the volume segment by the magnetic resonance system; and determination of a motion model of a motion within the volume segment as a function of the MR data. The motion model, as a function of a respective motion state of the motion, provides a correction specification for PET data which is acquired during this motion state. During acquisition of the MR data, specific MR data is acquired in the center of the k-space or of a straight-line segment which passes through the center of the k-space. The MR data determined is converted by a mathematical function into one value, as a function of which the respective motion state is determined.
