Microwave-Related Tissue Changes Using Ultrasound: Processing Images into Colors

AJAS · 2024

Zain Shariff · Washington State Academy of Sciences

Overview

Microwaves in the medical field are used to denature proteins and deactivate abnormal cells. Ultrasound helps define organ structures and identify abnormalities. In my previous study, increased duration of exposure of tissue to microwaves was associated with statistically significant increase in intensity of brightness of the images. Ultrasound images are monochromatic which results in underappreciation of the subtle changes in the brightness of tissue by the naked eye. By processing the variations in spectral colors of the brightness of the reflected ultrasound waves, it may be possible to recognize the changes and help apply them in clinical practice. This engineering study seeks to advance the knowledge of reflected waves by processing ultrasound images to spectral colors for recognizing tissue changes with microwave exposure. Ultrasound images of lamb muscular, lamb liver, and chicken muscular tissue before and after exposure to microwaves were studied. A total of 30 organic tissue images were studied. Although this was a statistically significant increase in brightness of each of the studied tissues on exposure to microwaves energy (chicken muscle 41% vs 72%; Lamb liver 33% vs. 65%; Lamb muscle 54% vs 71%), the changes on monochromatic images were not well appreciated. Using an algorithm to represent the images in spectral colors (altering the intensity of brightness into RGB value of a color) resulted in better appreciation of the changes. The finding of the study could possibly helpful in real time appreciation of the changes in tissue exposed to microwave energy in clinical practice.
