Synthetic aperture is a signal processing technique used to increase image resolution by synthesizing information from multiple subapertures, but the resolution improvement is limited by the physical size of the array transducer. Our co-robotic approach extends the effective aperture size by providing accurate tracking information and force-control compensation in a rapid execution.This concept can be…

Our proposed system addresses significant limitations in present-day robotic ultrasound research systems by enabling direct control of ultrasound imaging forces during co-manipulation. The proposed combined control based on hand-to-probe and probe-to-tissue force sensing enables development of a system that is intuitive to control and permits accurate control of forces to the patient with minimum physical…

The feasibility of the proposed epiretinal PAS mechanism was successfully evaluated in an ex vivo porcine retinal explant model using a Pd-Si layer that provides greater PA pressure and faster heat dissipation than previous epiretinal absorptive layers. The epiretinal PAS approach could be a option for less-invasive retinal prosthetic implant technology. The benefits of finer spatial control and a compact system would be enormous.
Peripheral nerve damage often produces serious problems in human life. By the fact that the peripheral nerve is not protected by rigid organ such as bone, it is at high risk of getting damage during surgery, daily life, and etc. For instance, during nerve sparing radical prostatectomy, peripheral nerves surrounding the prostate gland are easily…
