    摘要: An inflatable cuff having integrated ultrasound transducers is used to effect hemostasis of deep bleeding wounds in limbs. The cuff includes a chamber defined by a bladder or a series of dams into which a fluid may be introduced and pressurized. The pressure of the fluid stops or slows bleeding while high intensity focused ultrasound is applied to effect hemostasis. The fluid may also serve as an acoustic couplant between the limb and the ultrasound transducers. The transducers may be electrostrictive transducers. Diodes may be used to reduce parallel capacitive loading in the transducer array. Bypass capacitors using the electrostrictive material may also be used.

    摘要: Embodiments disclosed herein relate to a therapeutic ultrasound device spatial registration method and apparatus. The method enables locating a tissue target and surrounding tissue structures affecting the available acoustic beam paths to the target, relative to each individual therapeutic and diagnostic (e.g., imaging) transducer, in a device comprising a plurality of such transducers. By locating the target and tissue structures relative to each therapeutic transducer and/or array (e.g., in “local” coordinates) assists in transforming the locations relative to any transducers, enabling determination of which therapeutic transducers to use to treat the target, and specification of their respective ultrasound powers or energy, focal locations and beam patterns. The registration method employs a plurality of emitter and receiver acoustic sensors on, respectively, a plurality of imaging and therapeutic transducer device panels.
