Sonodynamic therapy ...

[36] Transcranial ultrasound is being tested for use in aiding tissue plasminogen activator treatment in stroke patients in the procedure called ultrasound-enhanced systemic thrombolysis.
Studies on localized prostate cancer showed that, after treatment, progression-free survival rates were high for low- and intermediate- risk patients with recurrent prostate cancer. [3] The InsighTec ExAblate 2000 was the first MRgFUS system to obtain FDA market approval, [4] US patent 5,247,935.
