Photoacoustic Device for Assessing Lymph Nodes
October 26, 2021 | Terry Sharrer
“[We, electrical engineers at South Korea’s Pohang University] demonstrate a non-ionizing, cost-effective, handheld photoacoustic finder (PAF) fully integrated with a solid-state dye laser and transparent ultrasound transducer (TUT). The solid-state dye laser handpiece is coaxially aligned with the spherically focused TUT. The integrated finder readily detected photoacoustic signals from a tube filled with methylene blue (MB) beneath a 22 mm thick layer of chicken tissue.” Their objective is to externally assess lymph nodes in the presence of breast cancer.
