主　　题：Photoacoustic tomography dry coupling water coupling finger joints 

摘      要：We present a systematical study on comparison between water and dry coupling in photoacoustic tomography of the humanfinger *** to the direct water immersion of thefinger for water coupling,the dry coupling is realized through a transparent PDMSfilm-based water bag,which ensures water-free contact with the *** results obtained suggest that the dry cou-pling provides image quality comparable to that by water coupling while eliminating the wrin-kling of thefinger joint caused by the water *** addition,the dry coupling offers more stable hemodynamic images than the water coupling as the water immersion of thefinger joint causes reduction in blood vessel size.
