Larynx

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Area of Science:

Medical Imaging
Biomedical Engineering
Image Processing

Background:

Motion is a significant challenge for in vivo, high-resolution larynx imaging.
Existing methods struggle with both rigid-body and nonrigid motion, limiting image quality.

Purpose of the Study:

To develop and evaluate a novel real-time motion compensation algorithm for larynx imaging.
To overcome limitations of previous algorithms by integrating rigid-body and nonrigid motion correction.

Main Methods:

Real-time processing of navigator data to compute displacement information.
k-space phase modulation for projection correction.
Automatic feedback system to reacquire data corrupted by nonrigid motion.
Combination of navigator-based rigid-body motion correction with a diminishing variance approach.

Main Results:

The algorithm successfully corrects for translations and reacquires data affected by nonrigid motion in phantom experiments.
Significant reduction in motion artifacts from bulk shift, swallowing, and coughing was observed in volunteer larynx imaging.
The combined approach prevents bulk motion from hindering algorithm convergence.

Conclusions:

The developed real-time motion compensation algorithm significantly enhances the quality of in vivo larynx imaging.
This technique offers a robust solution for mitigating motion artifacts in dynamic anatomical imaging.
The algorithm shows promise for improving diagnostic accuracy in laryngeal imaging applications.
