A Negative Lens Concept for Photoacoustic Tomography
Although a small point ultrasound transducer has a wide acceptance angle, its small active area leads to a high thermal-noise-induced electric voltage in the transducer, thus the sensitivity is low. By contrast, a finite size flat transducer has high sensitivity, but the acceptance angle is small, w...
