We present our study of pulsed-microwave-induced thermoacoustic tomography under a circular measurement configuration in biological tissues. A wide beam of short-pulse microwave (radio-frequency, RF) energy is used to illuminate a sample from the bottom. An unfocused ultrasonic transducer with a small aperture is used to record the thermoacoustic signals from the side. A backprojection method based on a rigorous theory is used to reconstruct the cross-sectional image from the measured data. The reconstructed image agrees with the original sample very well.
