  • Patent number: 12133728
    Abstract: The present disclosure is directed to relates to systems and methods for evaluating tissue using high intensity focused ultrasound (HIFU) energy. In one embodiment, for example, a system for treating a patient comprises an ultrasound source configured to deliver HIFU energy to a target tissue mass of the patient and a function generator operably coupled to the ultrasound source for initiating a pulsing protocol for delivering the HIFU energy. The system further comprises a controller configured to perform operations comprising applying HIFU energy to induce cavitation in the target tissue mass and cause a biomarker to be released, comparing a baseline concentration of the biomarker from a first fluid sample to a concentration of the biomarker in a second fluid sample within 2 hours after applying HIFU, and repeating the applying and comparing until the concentration of the biomarker in the fluid sample falls below a threshold value.

  • Publication number: 20170071515
    Abstract: The present disclosure provides methods of performing a liquid molecular biopsy on a subject using high intensity focused ultrasound (HIFU) energy. The present disclosure also provides methods of diagnosing a disease or a risk of a disease, such as a cancer, in a subject. The present disclosure further provides methods of treating one or more tissue masses (e.g., nodules, tumors, cysts, lesions, cells of unknown significance etc.) in a subject. In some embodiments, the methods are non-invasive or minimally invasive.
