Asymmetric RF Pulse for a Magnetic Resonance Imaging System - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522566 titled 'Asymmetric RF Pulse for a Magnetic Resonance Imaging System
Simplified Explanation
The abstract describes a method for constructing an asymmetric RF pulse for an MRI system. Here is a simplified explanation of the patent application:
- A first RF amplitude is determined for a first part of a time interval.
- An RF amplitude curve is received, depending on at least one RF curve parameter.
- A combined RF amplitude curve for the time interval is determined by combining the first RF amplitude with the RF amplitude curve for a second part of the time interval.
- The combined RF amplitude curve is optimized using a loss function, including an energy loss term based on the pulse energy and the RF curve parameter as an optimization variable.
- The combined amplitude of the asymmetric RF pulse is given by the optimized combined RF amplitude curve.
- Potential Applications
This technology can be applied in MRI systems to improve imaging quality and reduce scan times.

Original Abstract Submitted
For constructing an asymmetric RF pulse for an MRI system, a first RF amplitude for a first part of a time interval is determined and an RF amplitude curve, which depends on at least one RF curve parameter is received. A combined RF amplitude curve for the time interval is determined by combining the first RF amplitude for the first part of the time interval and the RF amplitude curve for a second part of the time interval, which succeeds the first part of the time interval. The combined RF amplitude curve is optimized using a loss function, which comprises an energy loss term, which depends on a pulse energy of the combined RF amplitude curve, and using the at least one RF curve parameter as at least one optimization variable. A combined amplitude of the asymmetric RF pulse is given by the optimized combined RF amplitude curve.
