Photoacoustic and thermoacoustic tomography of dog prostates


We developed a tri-modal system combining photoacoustic (PA) tomography, thermoacoustic (TA) tomography, and ultrasound (US) imaging. Acquired images of an excised dog prostate were compared to histology results. All three modalities can image distinct features. Features like the urethra were shown in both TA and US images, but TA gave a higher contrast-to-noise ratio. Fibrous tissue was more clearly imaged by TA, while the duct structure was better shown in PA images. These experimental results demonstrate the potential advantages of our tri-modal imaging system.
