Design, implementation, and analysis of a compressed sensing photoacoustic projection imaging system.

Significance: Compressed sensing (CS) uses special measurement designs combined with powerful mathematical algorithms to reduce the amount of data to be collected while maintaining image quality. This is relevant to almost any imaging modality, and in this paper we focus on CS in photoacoustic projection imaging (PAPI) with integrating line detectors (ILDs).

Aim: Our previous research involved rather general CS measurements, where each ILD can contribute to any measurement.
