Abstract

Photoacoustic imaging is a powerful biomedical imaging modality with the unique capability to perform many challenging imaging tasks due to its molecular contrast based on optical absorbers in tissue. This makes it ideal for applications such as functional brain imaging, and early detection of diseases such as cancer. By combining the optical detection method of a Fabry-Pérot Etalon with ultrafast single-shot compressed sensing techniques, this work aims to increase the temporal resolution of photoacoustic imaging by up to three orders of magnitude. This would allow real-time volumetric photoacoustic imaging while reducing complexity and cost, enabling difficult imaging tasks and expanding the clinical applicability.
