  • Publication number: 20250121214
    Abstract: Ultrasound transducer element arrays using acoustic ensonification drive patterns via a patient interface for sonosensitizer activation in sonodynamic therapy. Incoherent acoustic field generation varying phase, frequencies, and/or amplitude via controlled delivery of low intensity planar acoustic waves. Method includes generating a first and a second signal to generate respective acoustic ensonification drive patterns with phase, frequency, and amplitude and generating at least one relative phase, frequency or amplitude difference to generate a third incoherent acoustic ensonification pattern to activate a sonosensitizer. Calibration and complementary therapy procedures to improve cell susceptibility of cells to sonodynamic therapy are disclosed.

  • Publication number: 20250121217
    Abstract: Methods of treating tumors by administering compounds to a patient are provided. Compounds such as drugs, may be administered to the patient orally, by injection, intravenously, or topically, which then accumulate as compounds such as a protoporphyrin compound in tumor cells. After such accumulation, such compounds are then activated in various aspects to treat tumors cells, thereby treating cancer. Cancers such as glioblastoma may be treated.

  • Publication number: 20240278041
    Abstract: Disclosed are methods of using planar or defocused acoustic waves for providing non-invasive sonodynamic therapy. The method includes acoustically coupling an array of piezoelectric transducers to a patient. A controller is configured to generate an electrical drive signal at a frequency selected from a range of frequencies, modulate the drive signal, and drive the transducer with the modulated drive signal at the frequency to produce modulated acoustic waves to produce an average acoustic intensity sufficient to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.
