Abstract
Molecular Imaging techniques are a hotspot in oncology for their inherent ability to detect cancer early as well as characterize and stage them. The prognosis and treatment response can also be monitored with these imaging techniques. Specifically, photoacoustic imaging is a technique that recently had exponential growth in several biomedical applications, particularly for imaging tumors. Photoacoustic imaging involves excitation of the tissue with the nanosecond laser pulses and subsequent generation of acoustic waves with an ultrasound transducer. to reconstruct the image, has potential to detect and monitor cancer prognosis by using the optical contrast of hemoglobin. In this work, we evaluated the potential of LED-based photoacoustics in imaging heterogenous microvasculature in tumors.
