Fluorescence Lifetime Imaging Could Improve Cancer Surgery Outcomes
BOSTON, Oct. 24, 2023 — Extreme precision is required to surgically remove a cancerous tumor without damaging the surrounding healthy tissue. Yet surgeons often must rely on their eyes and hands to determine where to cut. Fluorescence lifetime (FLT) imaging, developed at Mass General Brigham by researchers who collaborated with several other institutions to evaluate the technique, could improve the precision of cancer surgeries. FLT imaging, a visualization technique for targeting cancer, combines high-speed
Noise-Resistant Method Enables Edge Detection Without Prior Imaging
HEFEI, China, Oct. 19, 2023 — Edge detection, the process of outlining objects in a scene by identifying areas where changes in color or intensity signal boundaries between objects, is vital in computer vision applications such as object recognition, image segmentation, and...
Beamforming Reduces Photoacoustic Image Bias
BALTIMORE, Oct. 17, 2023 — Photoacoustic (PA) imaging offers a noninvasive means to obtain molecular and functional information about a variety of medical conditions. However, the quality of PA images, which are acquired when light illuminates the skin, is affected by the...
