A new hand-held scanner developed by UCL researchers can generate highly detailed 3D photoacoustic images in just seconds, paving the way for their use in a clinical setting for the first time and offering the potential for earlier disease diagnosis.
In the study, published in Nature Biomedical Engineering, the team show their technology can deliver photoacoustic tomography (PAT) imaging scans to doctors in real time, providing them with accurate and intricate images of blood vessels, helping inform patient care.
Photoacoustic tomography imaging uses laser-generated ultrasound waves to visualize subtle changes (an early marker of disease) in the less-than-millimeter-scale veins and arteries up to 15mm deep in human tissues.
However, up until now, existing PAT technology has been too slow to...
