High frame rate 3D intracardiac echography (3D-ICE) might enable full-volumetric flow, tissue, and electro-mechanical wave tracking in the heart, thus supporting complex interventional procedures. Designing ICE transducers is very challenging due to the constraints imposed by the catheter's diameter on the transducer aperture and cable accommodation within the shaft. Current ICE probes only offer a 2D or limited 3D field of view at low frame rates. This work presents the design, fabrication, and characterization of an ICE prototype transducer aiming at high frame rate 3D imaging with a large field of view. @en

This article reports the results of fault injection on a microcontroller based on the RISC-V (Riscy) architecture. The fault injection approach uses fault simulation based on Modelsim and targets a set of 1000 fault injected per microcontroller block and per benchmarck. The chosen benchmarks are the Dhrystone and CoreMark that may represent generic workloads. The results show certain block are more prone to fault than others, as also confirmed by a vulnerability analysis that correlates the number of observed faults and the rate of access to the blocks.
