Abstract
A detector design is presented for scanning photoacoustic macroscopy that is based on several concentric ring-shaped elements made of PVDF. Compared to a spherical ultrasound lens, the array provides a long focal depth due to its dynamic focusing ability. It is shown that with ring elements that are inclined towards the region of interest in the sample, significantly better sensitivity and resolution are achieved compared to a planar array. This is demonstrated in a simulation. Based on the simulation results, an array detector was manufactured and its performance was tested in first phantom experiments.
