摘要： 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.

摘要： Disclosed is an ultrasound device for measuring blood flow velocity in a blood vessel of a subject without imaging functionality in the device. The measurement depends upon reflections of a collimated beam of ultrasound from a subject's body part. Received electrical signals representative of the reflected ultrasound energy is used for generating a representation of blood flow at a plurality of predetermined locations in the volume and calculating a first blood flow velocity at each of the locations. The representation of flow is used for delineating the blood flow in the blood vessel in the volume. An angle calculating unit calculates the Doppler angle between the direction of the radiated collimated beam in the delineated blood flow at each point. A velocity calculator calculates a second blood flow velocity at the plurality of points based on the calculated first velocities and the calculated angle at the point.

摘要： A device images time-wise in parallel using transducer elements of a group (428, 432, 436, 440). In some embodiments, the elements are of a current group and imaging is time-wise sequential by group. The groups may be spatially disposed (408, 412) with respect to each other so as to mutually intermesh element-wise. The imaging may include volumetric imaging. The device can be configured for not collectively using any of the elements to focus, nor to steer, a beam used in the imaging. The device might be operable to transition between spacing states (404, 408, 412) at least one of which is characterized by a respective minimum, nonzero, degree of intra-group, element-to-element non-adjacency (470), or may be fixed at one spacing state. The transitioning may be automatic, in response to input indicative of blood vessel size and/or depth.

摘要： A device for monitoring a subject for postpartum hemorrhage is disclosed. It comprises an ultrasound transducer for applying ultrasound energy focused at a region of uterine musculature of the subject for creating an acoustic radiation force for generating a shear wave in the uterine musculature. A second ultrasound transducer radiates ultrasound energy into the subject and receives the echoed ultrasound energy. By analyzing a signal representative of the received echoed ultrasound energy the speed of propagation of the shear wave in the uterine musculature is determined. The value of the tone of the uterine musculature is estimated based on the speed of propagation of the shear wave and conveyed to a user. Further, a device for detecting and locating a hemorrhage and estimating its severity are also disclosed.

摘要： Energy is transferred (336) to cause a mechanical property of biological tissue to change, as in ablation. An effect of the transferring is examined in more than one spatial dimension to, for example, make an ablation halting decision for a treatment region, i.e., line (312)or layer (314), or for a location (316) within the region. Halting decisions can be based on lesion-central and/or lesion-peripheral longitudinal displacement of treated tissue evaluated in real time against a characteristic curve. Steering in the azimuthal and/or elevation direction is afforded by, for example, linear, or 2D, multi-channel ultrasound arrays for therapy and imaging. Protocols includable are region-wide scanning (SI 010) and location-by-location completion for both (HIFU) therapy and tracking (acoustic-radiation-forced-based) displacement of treated tissue. Fine, location- to-location monitoring can be used for relatively inhomogeneous tissue; whereas, quicker, sparser and more generalized monitoring (1 100, 1200) can be employed for relatively homogeneous tissue.

The imaging system is operated to alternate between first and second operating modes. While the variable refractive lens is operated to alternate between a first configuration and a second configuration, the transducer is operated to alternate between generating acoustic radiation for displacing the viscoelastic medium and acoustic radiation for imaging the displacement of the viscoelastic medium. In embodiments the variable refractive lens is a fluid focus lens. Moreover, in embodiments, the imaging system is integrated with a catheter-based interaction modality, such as a tissue ablation modality.

摘要： 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.
