Curved-Array-Based Multispectral Photoacoustic Imaging of Human Finger Joints

Conclusions: The PVDF transducer has a better performance in bandwidth compared with commercial transducers. The curved design of the transducer offers a better sensitivity and a higher axial resolution compared with the flat design. Significance: Based on the phantom, animal, and human experiments, the proposed system has the potential to be used in clinical diagnosis of early-stage arthritis.
