| 20100160781 | DOPPLER AND IMAGE GUIDED DEVICE FOR NEGATIVE FEEDBACK PHASED ARRAY HIFU TREATMENT OF VASCULARIZED LESIONS - A noninvasive technique that can be used to deny blood flow to a particular region of tissue, without the inherent risks associated with invasive procedures such as surgery and minimally-invasive procedures such as embolization. Blood flow in selected portions of the vasculature can be occluded by selectively treating specific portions of the vasculature with high intensity focused ultrasound (HIFU), where the HIFU is targeted Doppler ultrasound data, and a duration of the therapy is automatically controlled using a negative feedback loop provided by Doppler ultrasound data collected during the HIFU therapy. A portion of the vasculature providing blood flow to the undesired tissue is selected by a clinician, or automatically selected based on Doppler data, and HIFU is administered to the selected portion of the vasculature to occlude blood flow through that portion of the vasculature. | 06-24-2010 |

| 20080275340 | ULTRASONIC TISSUE DISPLACEMENT/STRAIN IMAGING OF BRAIN FUNCTION - Tissue Pulsatility Imaging (TPI) is an ultrasonic technique developed to measure tissue displacement or strain in the brain due to blood flow over the cardiac and respiratory cycles. Such measurements can be used to facilitate the mapping of brain function as well as to monitor cerebral vasoreactivity. Significantly, because tissue scatters ultrasound to a greater extend than does blood, using ultrasound to measure tissue displacement or strain in the brain is easier to implement than using ultrasound to measure blood flow in the brain. Significantly, transcranial Doppler sonography (TCD) has been used to measure blood flow in the brain to map brain function and monitor cerebral vasoreactivity; however, TCD can only acquire data through the three acoustic windows in the skull, limiting the usefulness of TCD. TPI is not so limited. | 11-06-2008 |
