How do changes in focused ultrasound frequency affect anatomic specificity and efficacy in neurostimulation? Researchers in the US and China both studied this question in mice. A group in France has performed an in vivo, beating heart feasibility study for using focused ultrasound to perform cardiac ablation. Chinese researchers found improved short-term survival in patients treated with focused ultrasound plus chemotherapy when compared with chemotherapy alone for patients with unresectable pancreatic cancer.
