A parabolic mirror-based proximally actuated photoacoustic endoscope

We have developed a new photoacoustic endoscopic probe specifically designed for human urogenital imaging. The endoscopic probe uses a parabolic mirror-based mechanical scanning mechanism, providing an angular field of view of 270??. And it has a rigid, dome shaped end section for smooth cavity introduction. Here we introduce the new endoscope???s design and imaging principle, and present experimental results validating its in vivo imaging ability
