We explore new ways to use radiofrequency (RF)-induced thermoacoustic imaging (RF-Acoustics) for imaging applications. This non-invasive bioimaging technique has the potential to become an essential diagnostic tool for various diseases and cancers in the biomedical imaging community as it allows for deep tissue penetration, rich contrast, and high spatial resolution. Our work is both theoretical and experimental, with the aim of modifying the technique to minimize RF power transmitted into the body while still obtaining a high-quality image.
