Abstract Introduction Systemic sclerosis starts with an early phase characterized by Raynaud’s phenomenon, puffy fingers/hands, autoantibodies, and a scleroderma nailfold microscopic pattern. Alterations in the pattern are not evident all SSc patients. Photoacoustics (PA) high-frequency ultrasound (HFUS) could fulfill this need. The former can measure oxygen saturation while latter skin thicken...
Guided wave ultrasound can be applied to inspect large volumes of structures from a single transducer location and is particularly effective in one-dimensional such as rods, pipes rail. An application, which interest South Africa, the inspection rock bolts mining industry. The difficulty inspecting embedded rods that there rapid attenuation signals with distance. While guided systems generally ...
PURPOSE Currently, no clinical imaging modality is used routinely to assess tumor response to cancer therapies within hours to days of the delivery of treatment. Here, the authors demonstrate the efficacy of ultrasound at a clinically relevant frequency to quantitatively detect changes in tumors in response to cancer therapies using preclinical mouse models. METHODS Conventional low-frequency...
