Abstract

Photoacoustic imaging based on projection of Hadamard patterns is known to produce optical-resolution images with high contrast at low levels of radiant exposure. In this work, the requirements regarding noise level, a two-step reconstruction that reduces artifacts created by a focused detector and approaches to reduce the amount of acquired data without loss of image quality are discussed.
