Higher Mental Functions of the Brain: Language

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Background:

Parallel magnetic resonance imaging (pMRI) reconstruction requires extensive parameter tuning for optimal image quality.
While data-driven AI has advanced pMRI, knowledge-driven AI for optimization remains underutilized.

Purpose of the Study:

To develop an intelligent agent using LLM-based planning for optimizing pMRI reconstruction.
To leverage LLMs for automating and improving the parameter tuning process in pMRI.

Main Methods:

An LLM generated Planning Domain Definition Language (PDDL) domain and problem files from empirical knowledge.
Structured PDDL was employed to guide the GRAPPA reconstruction process.
An intelligent agent integrated LLM planning for pMRI parameter optimization.

Main Results:

LLM-based planning successfully translated unstructured knowledge into clear parameter tuning goals.
The proposed method demonstrated improved image reconstruction quality in pMRI.
The system facilitated optimization for users less familiar with pMRI reconstruction intricacies.

Conclusions:

LLM-based planning offers a novel approach to optimize pMRI reconstruction by leveraging AI.
This method enhances image quality and accessibility for MRI technologists.
Future research aims for fully automated pMRI reconstruction without human intervention.
