20100274130 | SYSTEMS AND METHODS FOR TRACKING AND GUIDING HIGH INTENSITY FOCUSED ULTRASOUND BEAMS - The present disclosure provides systems and methods for tracking and guiding high intensity focused ultrasound beams (HIFU). More particularly, the disclosed systems and methods involve use of acoustic radiation force impulse (ARFI) imaging to detect the focal position of an HIFU capable transducer relative to a target area. The focal position may then be 5 compared to a desired treatment location and the orientation and focus of the transducer may be adjusted accordingly so as to reconfigure and/or refocus the HIFU beam relative to the desired treatment location. The desired treatment location may be dynamically determined using bleed detection and localization (BD&L) techniques. Thus, the desired treatment location may be determined using 3D Doppler ultrasound based techniques, wherein changes in quantitative 10 parameters extracted from the Doppler spectra, e.g., Resistance Index (RI), are used to detect and localize a bleeding site for treatment. | 10-28-2010 |

20140180114 | METHOD AND DEVICE FOR DETECTING OCCLUSION/REOPENING OF AN ARTERY AND SYSTEM FOR MEASURING SYSTOLIC BLOOD PRESSURE - This invention provides a method and a device for detecting occlusion and/or reopening of an artery of a body caused by a changing pressure applied on the artery as well as a system for measuring the systolic blood pressure of an artery of a body. The method comprises the steps of: obtaining a blood flow signal indicative of a change of the blood flow in the artery caused by the changing pressure, using a Doppler Ultrasound transducer attached to the exterior of the body; deriving, from the blood flow signal, at least one variable of a first variable indicative of the magnitude of the blood flow and a second variable indicative of the periodicity of the blood flow; and detecting the occlusion and/or reopening of the artery on the basis of the at least one variable. In this way, the occlusion/reopening of the artery can be detected automatically. Since the need to manually detect the occlusion and reopening of the artery by listening with a stethoscope or a Doppler probe is eliminated, the detecting result is more predictable and repeatable, and therefore also more accurate. | 06-26-2014 |
