Phase Contrast MR Imaging with Velocity Encoding

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

This invention describes a method for phase contrast magnetic resonance imaging (MRI) that incorporates speed encoding to more precisely measure the movement of fluids, such as blood, in the body. By acquiring MR signals and reconstructing several images with mathematically processed pixel values, the method allows for the creation of both standard reference images and images with motion information encoded.

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

• Medical imaging for examining blood flow in vessels and the heart
• Detection of vascular abnormalities such as stenosis or aneurysms
• Evaluation of cardiac function by visualizing blood movement
• Assessment of cerebrospinal fluid flow in neurological diseases
• Non-invasive monitoring of treatment outcomes for vascular diseases

BenefitsContent extracted from patent full text and abstract with AI.

• Improved accuracy in measuring flow velocities in the body
• Enhanced imaging of moving biological fluids for better diagnosis
• Non-invasive and detailed assessment of vascular and cardiac conditions
• Potentially reduced need for contrast agents due to improved imaging techniques
• More comprehensive and reliable diagnostic information for clinicians

Patent Abstract

MR signals are acquired with a method for phase contrast magnetic resonance (MR) imaging with speed encoding, in order to acquire raw data for multiple MR images. The multiple MR images are reconstructed. For this purpose, matrix elements are determined for numerous matrices, wherein the sum of the numerous matrices results in a pixel matrix. The pixel matrix has matrix elements that represent the pixel values for a reference MR image with flow compensation. The pixel matrix has further matrix elements that represent the pixel values for the at least one MR image with speed encoding. The matrix elements of the numerous matrices are determined such that a first matrix of the numerous matrices fulfills a first condition.
