Abstract

In this study, we present phantom experiments and in-vivo human examination to evaluate the possibility of threedimensional (3D) photoacoustic imaging of the finger joints in a spherical scanning geometry. The phantom results show that 1mm thick "cartilage" can be accurately differentiated from the "bones" with a 1 MHz transducer. Results based on in-vivo finger joint study show that major anatomical features in the joint can be imaged, and the cartilages associated with the joint can be differentiated well from the phalanx. The results shown in this paper suggest that 3D PAT in a spherical scanning geometry has the potential to be used for early diagnosis of joint diseases
