Test Body for Magnetic Resonance, Positron Emission or SPECT Tomographs, Method for its Manufacture and Use of the Test Body

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

This invention relates to a specially designed test object (phantom) for use in Magnetic Resonance (MRI), Positron Emission Tomography (PET), and SPECT imaging devices. The phantom features micro-cavities—smaller than the imaging system's resolution—distributed throughout its structure, which can be filled with liquids or solutions containing imaging agents. These micro-cavities prevent imaging artifacts such as standing waves in the liquid, leading to improved image quality. The test object is manufacturable using 3D printing and can be easily tailored in shape and size to mimic different body organs or geometries.

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

• Calibrating and quality assurance of MRI, PET, and SPECT scanners in hospitals and research centers.
• Development and validation of new medical imaging and image reconstruction methods.
• Phantom studies for simultaneous PET/MRI hybrid imaging systems.
• Training medical personnel in imaging protocols with realistic test objects.
• Testing new radiotracers or MRI contrast agents in a controlled, repeatable manner.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces imaging artifacts in MRI, PET, and SPECT scans compared to traditional water phantoms.
• Provides artifact-free images even with short-lived PET isotopes or specific contrast agents.
• Easily customized shapes and internal structures using 3D printing technology.
• Reusable and simple to refill with various fluids, enabling flexible experiments and QA routines.
• No requirement for complex chemical additives to address standing waves, simplifying preparation.
• Enables more accurate and reliable scanner calibration, leading to better diagnostic outcomes.

Patent Abstract

The invention relates to a test body for application in magnetic resonance, SPECT and/or positron emission tomographs, said test body having, at least in portions, cavities for receiving liquids, which cavities have an extent that is smaller than the image resolution of a SPECT, magnetic resonance and/or positron emission tomograph, and to the use of same for preventing interference of the liquid situated in the test body, and to a method for producing the test body by means of a 3D printing technique.
