Method for Creating an Attenuation Correction for a Combined Magnetic Resonance-Positron Emission Tomography Device

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

This invention describes a method and computer program for generating an attenuation map, which corrects for image distortions in PET scans when using combined Magnetic Resonance (MR) and Positron Emission Tomography (PET) devices. The system detects the positions of hardware components within the imaging device and uses this information to more accurately correct PET data, ensuring clearer and more reliable imaging results.

Patent Abstract

A method, a computer program product and a computer readable storage medium are disclosed for generating a global attenuation map used for attenuation correction of positron emission tomography image data sets in a combined magnetic resonance-positron emission tomography device. In an embodiment, during the course of detecting hardware components of the combined magnetic resonance-positron emission tomography device and determining positions of the detected hardware components relative to a patient support, the global attenuation map is generated as a function of the detected hardware components.
