Background:

Abdominal obesity is a primary cause of metabolic syndrome.
Computed tomography (CT) scans accurately diagnose abdominal obesity but are costly, cumbersome, and involve radiation risks.
There is a need for safer, more accessible methods for abdominal fat assessment.

Purpose of the Study:

To develop a novel device utilizing electrical impedance tomography (EIT) for abdominal fat imaging.
To create a safer and more practical alternative to CT scans for assessing abdominal obesity.
To evaluate the feasibility of EIT for differentiating subcutaneous and visceral fat.

Main Methods:

A 32-electrode EIT device with a pneumatic attachment mechanism was designed.
Alternating current (1.0 mArms at 500 kHz) was applied, and voltage data were collected.
Image reconstruction software was developed using finite element methods and the Marquardt method to solve the inverse problem.

Main Results:

The EIT device successfully imaged human abdominal subcutaneous fat.
Muscles surrounding the viscera were also visualized.
Imaging quality for visceral fat requires further improvement, but preliminary results are promising.

Conclusions:

The developed EIT device shows potential as a safe and practical tool for abdominal fat scanning.
Further advancements in imaging algorithms and hardware may enhance visceral fat visualization.
This technology could offer a valuable alternative for metabolic syndrome risk assessment.
