Abstract: Biological photoacoustic tomography (PAT) imaging is a newly developed imaging modality for the early diagnosis and treatment of diseases. By PAT imaging, the optical absorption distribution of biological tissues can be reflected and the optical absorption and scattering coefficients of the tissues can be quantitatively measured, and then the functional composition of tissues can be analyzed. In clinical applications, ultrasonic detectors can only scan within a limited range of angles due to the limitations in particularity of the target morphology, mechanical structure, spatial location and imaging time. Thus, artifacts and distortions may occur in the reconstructed images caused by sparse sampling data. In this paper, the current methods solving limited-view PAT image reconstruction from sparse measurement are summarized. Existing problems are also analyzed.
