Synthetic aperture ultrasound imaging with a ring transducer array: preliminary ex vivo results
TL;DR: The proposed ring transducer array and SA ultrasound imaging method were shown to be capable of producing isotropic high-resolution images whose quality was independent of depth.

Improving high-intensity focused ultrasound beam imaging via a backscattering suppression algorithm
Kazuhiro Matsui,Takashi Azuma,Keisuke Fujiwara,Hideki Takeuchi,Kazunori Itani,Junchen Wang,Toshihide Iwahashi,Etsuko Kobayashi,Ichiro Sakuma +8 more
TL;DR: A novel backscattering suppression algorithm based on an inverse problem approach to retrieve HIFU beam components was proposed and validated in ex vivo experiments in conjunction with focal spot shifts and beam width variations, demonstrating the clear improvement of HifU beam imaging quality.

Photoexcited-Charge Transfer and Energy–Storage Reaction of Photorechargeable TiO2/Carbon Fibers Composite Electrodes
TL;DR: In this article, the photoexcited charge transfer and energy-storage reaction were studied and it was concluded that the low formation rate of lithiated carbons was one of the causes of small photocharged quantities.

Limb muscle sound speed estimation by ultrasound computed tomography excluding receivers in bone shadow
Xiaolei Qu,Takashi Azuma,Hongxiang Lin,Hideki Takeuchi,Kazunori Itani,Satoshi Tamano,Shu Takagi,Ichiro Sakuma +7 more
TL;DR: The bent-ray method is modified to produce SOS images for limb muscle with bone inside and simultaneous algebraic reconstruction technique (SART) is employed to correct SOS along ray paths, but excluding paths with low energy wave which may pass through bone.
