The high-ranking journal Ultrasonics (Q1, IF 4.1) published our paper on the study of the effect of alendronate therapy on skull density, structure, and the efficacy of focused ultrasound brain therapy. The research was conducted by LIMU research fellows, Alisa Krokhmal and Vera Khokhlova, along with PhD student Daria Chupova, in collaboration with the V.S. Buzaev International Medical Center.
Our paper titled “Respiratory motion effects and mitigation strategies on boiling histotripsy in porcine liver and kidney” has been published in a highly rated journal IEEE Transactions on Ultrasonics, Ferroelectric, and Frequency Control (Q1, IF 3.0).
