Method for Operating an Imaging Diagnostic Device, Computer Program, and Diagnostic Device

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

This invention relates to a method, computer program, and system for operating an imaging examination device (such as MRI, CT, PET, or other tomographic scanners). It improves the accuracy of image slice selection by compensating for gradient field distortions, which can cause displacement and rotation of the imaged sections. The method prospectively adjusts the coordinates used for imaging, ensuring that the acquired image slice matches the desired location in the object, even in areas further from the magnet's center, where distortions are more pronounced.

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

• MRI, CT, or PET scans for improved anatomical imaging accuracy, especially in peripheral zones of the imaging field.
• Medical interventions (e.g., image-guided surgery or biopsies) requiring precise localization of instruments or target structures.
• Research imaging where high spatial fidelity is critical, such as neuroscience or oncology studies.
• Retrofitting existing imaging devices with enhanced software to improve image localization.
• Live or real-time imaging support for interventions demanding consistent and accurate image planes.

BenefitsContent extracted from patent full text and abstract with AI.

• Ensures that the actual imaged slice matches the intended anatomical plane, reducing errors due to gradient non-linearity.
• Enhances safety and efficacy in image-guided procedures by reliably displaying the correct target area.
• Extends precise imaging capabilities further from the device's center, increasing operational flexibility.
• Reduces need for post-processing corrections and repeat scans, saving time and resources.
• Can be implemented through software upgrades and does not always require major hardware changes.
• Supports real-time corrections, enabling use during live medical procedures.

Patent Abstract

The invention relates to a method for operating an imaging examination device (1), wherein signals are received from an object (5) to be examined and are identified and displayed in layers in the form of sectional images and/or three-dimensional images of the object (5), having the following steps: • a) ascertaining a desired imaging layer (4) of the object (5) to be examined, • b) determining the coordinates of a desired target point (6) in the desired imaging layer (4), • c) determining the coordinates of a corrected target point (6') while taking into consideration a distorted gradient field of the examination device (1) such that the examination device detects an imaging layer on which the desired target point (6) lies on the basis of the distorted gradient field while using the corrected target point (6') instead of the desired target point (6), and • d) detecting an imaging layer (4) by means of the examination device (1) using the corrected target point (6') and visualizing an image obtained therefrom.
