The SIBUS‐IN Fingerheld Ultrasound Machine
Journal of Cosmetic Dermatology, Volume 24, Issue 7, July 2025.ABSTRACT Background Minimally invasive esthetic procedures risk vascular occlusion, necrosis, and other sequelae; real‐time ultrasound guidance mitigates these events, yet conventional devices are bulky and two‐handed. Aim To present the SIBUS‐IN fingerheld ultrasound system and summarize its technical features and clinical advantages for esthetic ...
