Significance: Optical-resolution optoacoustic microscopy (OR-OAM) enables label-free imaging of the microvasculature by using optical pulse excitation and acoustic detection, commonly performed by a focused optical beam and an ultrasound transducer. One of the main challenges of OR-OAM is the need to combine the excitation and detection in a coaxial configuration, often leading to a bulky setup that requires physically scanning the ultrasound transducer to achieve a large field of view.
Aim: The aim of this work is to develop an OR-OAM configuration that does not require physically scanning the ultrasound transducer or the acoustic beam path.
Article Synopsis
- A new optoacoustic imaging system using an epi-illumination setup allows for point-by-point imaging while scanning the illumination with a detector, improving efficiency.
- This innovative approach enables imaging at depths of up to 5 mm in phantoms and successfully demonstrates vascular imaging in a live mouse ear.
- Unlike traditional methods that require static light sources, this system takes advantage of light diffusion, allowing more flexibility in illumination while still producing high-quality images.
