Multiangle Long-Axis Lateral Illumination Photoacoustic Imaging to Evaluate Tumor Oxygenation

Photoacoustic imaging (PAI) is an emergent technique with a wide range of biomedical applications. An interesting application of PAI is the non-invasive estimation of tissue oxygenation, which is an important parameter for early prediction of tumor response to treatment. PAI is directly affected by light fluence distribution within the target; therefore, efficient light delivery is essential to ge...
