In this study, we investigate a patterned thin metal film (PTMF) deposited on a transparent plate for its feasibility as a resolution test target for PAT. The major challenge in this work is to distinguish components of the ultrasound generated on the metal film delivered to the transducer for PAT image reconstruction. Depending on the sound component detected by the transducer, measured resolution of PAT using PTMF will be either for the imaging in the Figure 3 (a) Digital photography and (b) a full 360 degree PAT image of the positive PTMF sample.
