“…Hence, the Fredholm integral eigenvalue problem in ( 2) is discretized and simplified to the (infinite) matrix eigenvalue problem shown in Equation (14). For numerical simulations, the problem in Equation (14) needs to be truncated to a finite dimension. The terms in Q k,m eventually go to zero for sufficiently large indices.…”

“…Photoacoustic imaging systems for biomedical applications combine the advantages of both optical and acoustical imaging methods and have thus been attracting researchers' attention in recent decades [1][2][3][4][5]. Many attempts have been made to improve the Signalto-Noise Ratio (SNR) of a photoacoustic imaging system [6][7][8][9][10][11][12][13][14]. However, in the context of the selection of the transmitted waveform, most recent studies are still based on either chirps or square pulses, and occasionally Gaussian pulses [15,16] or pulse trains similar to pulsed sinusoids with a high-carrier frequency [17].…”

“…In the Bayesian setting, errors due to uncertainties in the SoS can be compensated for using Bayesian approximation error modelling [27] , but the method is computationally intensive. More practically, methods have been proposed to estimate the SoS automatically, by maximising an image quality metric or similar [28] , [29] , [30] , [31] , [32] , [33] . However, all of these proposed methods for accounting for SoS heterogeneities in PA reconstruction either require additional hardware, prior knowledge of the target, or cannot be applied in real-time, or are not applicable to the one-sided measurements of interest here.…”

“…Noninvasive imaging of blood vessels can be performed by PAI to provide high-resolution vascular imaging for preoperative planning. Photoacoustic computed tomography (PACT) 29 , 30 is an embodiment of PAI. Compared with ultrasound imaging, PACT has rich internal and external optical contrast, and it has advantages in high-resolution imaging of subcutaneous microvessels 31 , 32 .…”
