Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Background:

Microwave imaging offers a promising, non-ionizing method for breast cancer detection.
Existing simulation methods for microwave imaging systems like MammoWave can be computationally intensive.

Purpose of the Study:

To develop and validate an analytical simulation approach for the MammoWave microwave imaging system.
To assess the accuracy of the proposed simulation by comparing it with phantom measurements.

Main Methods:

The simulation is based on the theory of cylindrical waves emitted by line sources.
The breast tissue and potential tumor are modeled as a cylinder with an inclusion.
The approach considers a frequency band of 1-9 GHz.

Main Results:

The analytical simulation achieved an average relative error of less than 6% when compared to phantom measurements.
The simulation accurately models MammoWave systems with multilayered eccentric cylinders.

Conclusions:

The proposed analytical simulation provides an efficient and accurate method for understanding MammoWave's detection capabilities.
This approach can significantly reduce the need for time-consuming full-wave simulations and physical phantom measurements in system development and validation.
