PHOTOACOUSTIC TOMOGRAPHY (PAT)

Description

Photoacoustic tomography (PAT) is a cutting-edge imaging technique that combines the advantages of optical and ultrasound imaging. By using short laser pulses to generate acoustic waves in tissue, PAT can create high-resolution, 3D images of biological tissues. This technique is especially useful for visualizing blood vessels due to the strong absorption of hemoglobin, and can also be used for deep tissue imaging with centimeter-level penetration depth. PAT is a non-invasive method that does not require contrast agents, making it quick and easy to use. When combined with other imaging techniques like optical coherence tomography or widefield microscopy, PAT provides researchers with even more powerful tools for studying biological tissues.
