A practical solution to improve the field of view in circular scanning‐based photoacoustic tomography

Journal of Biophotonics, Volume 17, Issue 9, September 2024.
One of the primary challenges in ring single‐element photoacoustic tomography systems is the low image quality in areas away from the center of the ring. To address this shortcoming, we have put forward a practical and straightforward solution to enhance the FOV of circular scanning‐based photoacoustic tomography (CS‐PAT).
