摘要： An ultrasonic diagnostic and therapy system is described for stopping the bleeding of severely damaged blood vessels or vessels severed in a limb amputation. A cuff is attached to the stump of the severed limb which contains a diagnostic transducer array and a HIFU transducer. The diagnostic transducer surveys the tissue of the severed limb, searching for a Doppler flow signal. When a Doppler flow signal is detected, the range to and coordinates of the sample volume where the flow was detected are determined, as well as the flow velocity. This information is supplied to a HIFU therapy transducer controller, which controls the HIFU transducer to transmit focused ultrasound to the sample volume of the flow locus, the center of the lumen of a blood vessel. The focused ultrasound heats and coagulates blood in the severed vessel to stem the bleeding. Heat dissipation due to the blood flow is reduced by tracking and continuously heating the same bolus of blood as it flows, or by heating a significant length of the blood vessel instead of a fixed spot in the vessel.

摘要： An ultrasonic diagnostic and therapy system is described for stopping the bleeding of severely damaged blood vessels or vessels severed in a limb amputation. A cuff (30) is attached to the stump of the severed limb which contains a diagnostic transducer array and a HIFU transducer (42, 44).

When a Doppler flow signal is detected, the range to and coordinates of the sample volume where the flow was detected are determined, as well as the flow velocity. This information is supplied to a HIFU therapy transducer controller, which controls the HIFU transducer to transmit focused ultrasound to the sample volume of the flow locus, the center of the lumen of a blood vessel.

摘要： An ultrasonic diagnostic and therapy system is described for stopping the bleeding of severely damaged blood vessels or vessels severed in a limb amputation. A cuff (30) is attached to the stump of the severed limb which contains a diagnostic transducer array (52, 54, 56) and a HIFU transducer (42, 44). The diagnostic transducer surveys the tissue of the severed limb, searching for a Doppler flow signal. When a Doppler flow signal is detected, the range to and coordinates of the sample volume where the flow was detected are determined, as well as the flow velocity. This information is supplied to a HIFU therapy transducer controller, which controls the HIFU transducer to transmit focused ultrasound to the sample volume of the flow locus, the center of the lumen of a blood vessel.

摘要： An ultrasonic imaging system uses a specially configured scanhead to provide ultrasound return signals that are processed by an imaging unit to generate a three-dimensional Doppler ultrasound image. One embodiment of the scanhead includes a first pair of apertures aligned along a first axis, and a second pair of apertures aligned along a second axis that is perpendicular to the first axis. All of the apertures lie in a common plane. Respective signals from the apertures along each axis are processed to generate two-dimensional Doppler motion vectors. The resulting pairs of two-dimensional Doppler motion vectors are then processed to generate three-dimensional Doppler motion vectors that are used to generate a three-dimensional Doppler image. In another embodiment, three co-planar apertures are arranged equidistantly from each other about a common center, and the three-dimensional Doppler image is generated from respective signals from the apertures.

摘要： A distributed diagnostic imaging system (62) and method includes a data processor coupled to a variety of diagnostic imaging components through a network (80). The diagnostic imaging components include acquisition devices (90) that are used to obtain diagnostic imaging signals, displays (98) on which obtained images can be viewed, and control units (94) that are used with either acquisition units (90) or displays (98) to control the manner in which an image is obtained or displayed. The distributed nature of the system (62) makes it relatively easy and inexpensive to upgrade or modify individual imaging components, and allows the businesses of selling, distributing, and upgrading an imaging lab, and obtaining and reviewing diagnostic images to be conducted in a novel manner, such as by costing an imaging procedure on a “per use” basis.
