Recording of Diagnostic Measurement Data of a Heart by Means of a Magnetic Resonance Device

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

This patent describes a method and apparatus for recording diagnostic measurement data of the heart using magnetic resonance imaging (MRI). The invention uses a specific control sequence with strong RF excitation, collects data in a coordinate system not tied to the heart's movement, and operates at a magnetic field strength of less than 1.0 tesla.

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

• Early detection and monitoring of heart diseases using low-field MRI systems
• Cardiac imaging in hospitals, outpatient clinics, and mobile diagnostic units
• Non-invasive assessment of cardiac function in patients unable to undergo high-field MRI
• Use in developing regions where only low-field (less expensive) MRI equipment is available

BenefitsContent extracted from patent full text and abstract with AI.

• Enables high-quality cardiac imaging at lower magnetic field strengths, which can reduce equipment costs and make MRI more accessible
• Improved diagnostic accuracy as the method is less sensitive to heart movement and patient motion
• Reduced safety concerns for patients with certain implants or medical conditions, who cannot use high-field MRI
• Potential for wider application outside major hospitals due to lower equipment requirements

Patent Abstract

In a method and magnetic resonance apparatus for recording diagnostic measurement data of a heart of an examination object, the magnetic resonance apparatus is operated by a control sequence wherein an RF pulse excites nuclear spins with a flip angle of at least 60°, the diagnostic measurement data are recorded in a coordinate system independent of the heart, and the basic magnetic field produced by the magnetic resonance apparatus is smaller than 1.0 tesla.
