Investigation of the far-field approximation for modeling a transducer's spatial impulse response in photoacoustic computed tomography()
When ultrasonic transducers with large detecting areas and/or compact measurement geometries are employed in photoacoustic computed tomography (PACT), the spatial resolution of reconstructed images can be significantly degraded. Our goal in this work is to clarify the domain of validity of the imagi...
