Scanning Microwave Induced Acoustic Tomography
Abstract
The combination of ultrasound and microwave has provided us a unique opportunity for early-cancer imaging with high resolution and high contrast. We have made significant technical progress in thermoacoustic imaging including data acquisition and imaging reconstruction. Specifically, our accomplishments include (1) an exact and an approximate time-domain reconstruction algorithm for thermoacoustic tomography in a spherical geometry was derived, (2) an exact frequency-domain reconstruction algorithm for thermoacoustic tomography in a planar geometry was derived, (3) an exact frequency-domain reconstruction algorithm for thermoacoustic tomography in a cylindrical geometry was derived, (4) high-resolution and high-contrast images were obtained, (5) further progress was made in the reconstruction algorithms, in the understanding of heterogeneity, and in extending the technology to other electromagnetic sources. We have imaged mastectomy specimens at M.D. Anderson Cancer Center in Houston.
