<b>Volumetric ultrasound and photoacoustic imaging of inflammatory arthritis in human finger joints via robotic arm powered arc scans</b> Open
Ultrasound (US) imaging is a standard clinical tool for assessment of soft tissue inflammation, particularly for imaging the peripheral joints of the hands and feet, which are usually the first to be affected by rheumatoid arthritis. Robot…

Robotics and optical coherence tomography: current works and future perspectives [Invited] Open
Optical coherence tomography (OCT) is an interferometric technique for micron-level imaging in biological and non-biological contexts. As a non-invasive, non-ionizing, and video-rate imaging modality, OCT is widely used in biomedical and c…
