Cardiac q-space trajectory imaging by motion-compensated tensor-valued diffusion encoding in human heart in vivo

Purpose: Tensor-valued diffusion encoding can probe more specific features of tissue microstructure than what is available by conventional diffusion weighting. In this work, we investigate the technical feasibility of tensor-valued diffusion encoding at high b-values with q-space trajectory imaging (QTI) analysis, in the human heart in vivo....

Non-Assembly Walking Mechanism Utilizing a Hexapod Gait

Small inspection robots allow for the optimal exploration of environments and the collection of data from challenging areas, particularly where there may be small access points or tight and fragile surroundings. These robots can be custom-built for specific tasks, but the design and assembly process for this can be costly, both in resources and...

Autonomous control for miniaturized mobile robots in unknown pipe networks

Despite recent advances in robotic technology, sewer pipe inspection is still limited to conventional approaches that use cable-tethered robots. Such commercially available tethered robots lack autonomy, and their operation must be manually controlled via their tethered cables. Consequently, they can only travel to a certain distance in pipe,...
