Deep-Tissue Photoacoestic Tomography of a Genetically Encoded Near-Infrared Fluorescent Probe

摘要

Non-invasive studies of physiological and pathogenic processes in deep tissues require both new imaging techniques and advanced probes. One of the emerging approaches is photoacoustic (PA) tomography, which is a hybrid technique built on the PA effect. PA imaging relies on the thermo-elastic expansion of light-absorbing objects and subsequent production of ultrasonic waves, which are then detected and quantified.
