| 1 | The sparse array elements selection in sparse imaging of circular-array photoacoustic tomography显示文摘Photoacoustic imaging(PAI)has been developed,and photoacoustic computed tomography(PACT)is widely used for in vivo tissue and mouse imaging.Simulated annealing(SA)algorithm solves optimization problems,and compressed sensing(CS)recovers sparse signals from undersampled measurements.We aim to develop an advanced sparse imaging framework for PACT,which invloves the use of SA to¯nd an optimal sparse array element distribution and CS to perform sparse imaging.PACT reconstructions were performed using a dummy and porcine liver phantoms.Compared to traditional sparse reconstruction algorithms,the proposed method recovers signals using few ultrasonic transducer elements,enabling high-speed,low-cost PACT for practical application. | Zezheng Qin Yang Liu Junke Chi Yiming Ma Mingjian Sun | 2022 | Journal of Innovative Optical Health Sciences2022，15，5： | 0 |
