摘要： A medical diagnostic ultrasound system is described in which ultrasonic B mode tissue information and Doppler flow information is acquired from a volumetric region of the body and processed in an interleaved sequence to render a three dimensional image. The three dimensional rendering processes the B mode and Doppler flow information to give priority to tissue information, flow information, or a blend of the two.

摘要： A remotely upgradeable medical diagnostic ultrasound system is described which is upgradeable with a new transducer probe by means of air shipment of the upgrade hardware and remote transmission of upgrade data which controls operation of the probe. The ultrasound system includes a data communicator such as a network link or modem for receiving upgrade data from a remote location. A process for upgrading the system is provided whereby a communications link is established over a common carrier communications medium between the ultrasound system and a remote terminal, which transmits upgrade program data to the ultrasound system. The program data portion of an upgrade is provided via the communications link while the hardware portion of the upgrade is shipped by air freight to the user. In this way, an ultrasound upgrade can be provided to a user from a remote location in a matter of hours.

摘要： A multiplane TEE probe is provided in which an aluminum sheet is embedded in the acoustic lens in front of the transducer to dissipate heat which accumulates in the lens. The embedded aluminum foil sheet in front of the transducer helps reduce such heat buildup by spreading out heat which develops at hot spots and conducting the heat trapped in the lens material to a heatsink mass behind the transducer and away from the patient contacting surface of the probe. A mylar sheet covers the front of the transducer. The inner surface of the mylar sheet is aluminized. This aluminum layer in the inner surface of the cover serves a like purpose.

摘要： An ultrasonic imaging system is disclosed which produces a sequence of images of planes of a subject including both image and spatial positional information of the image plane. In one embodiment the positional information is developed from a plurality of accelerometers located within a scanhead. The second integrals of the acceleration signals are used to determine positional information of the image plane. In a second embodiment a transmitter transmits a magnetic field and a receiver attached to the scanhead detects the position of the scanhead in relation to the transmitted magnetic field. Spatially related images are displayed by displaying one image plane in the plane of the display and a second image plane projected in relation thereto. Either of the displayed planes may be displayed in outline form, and the outline may be modulated to depict depth.

摘要： A method and apparatus are described for testing the integrity of an ultrasonic transducer probe or the ultrasound system connected to the probe. The elements of the transducer are pulsed at a time when the probe is not in contact with a patient and the surface of the probe lens is exposed to the open air. The channel electronics receives the echo signal returned from the lens-air interface and reverberations between this interface and the transducer. These signals are analyzed by a diagnostic processor coupled to the channel electronics for characteristics such as amplitude, time of echo reception, group delay, and other characteristics to determine the possible existence of problems such as faulty transducer elements or connections and problems in the system receive electronics. The diagnostic processor can adaptively adjust an operating characteristic of the system electronics such as gain or time delay to compensate for a detected out of tolerance condition.

摘要： An ultrasonic diagnostic imaging system is provided which calibrates and quantifies colors of a color power Doppler display to produce quantified measurements of Doppler power intensity. The colors of a color power Doppler image are divided into discrete colors and each color assigned a quantified measure of the Doppler power intensity indicated by that color. When a user moves a cursor over the image the system compares the color of the pixel where the cursor is located with the range of colors and their quantified measures and produces a quantified measure of the Doppler power intensity at the location of the cursor. A line of such measures across a blood vessel can be used to plot a profile of Doppler power intensity across the vessel, and an index number which is a measure of perfusion in a region of the body is determined from an area of a color power Doppler image.

摘要： An ultrasonic diagnostic system is provided which detects the presence of coated microbubble contrast agents in the body of a patient by transmitting ultrasonic energy which causes the destruction of the coated microbubbles and detects the microbubble destruction through phase insensitive detection and differentiation of echoes received from two consecutive ultrasonic transmissions. The destruction of a microbubble can also be used as a point source of acoustic energy for aberration correction, whereby the timing of the beamformer is adjusted from an analysis of beamformer signals resulting from a detected microbubble destruction event.

摘要： An intraoperative ultrasonic transducer probe is described comprising a handle section and a transducer section which resemble a tiny leg and foot. The two sections are obtusely angled relative to each other so that the physician may continue to clearly view the surgical site while holding and manipulating the probe. The extension of the transducer section away from its point of attachment to the handle section results in the toe of the foot being insertable under unincised tissue, enabling the surgeon to ultrasonically examine organs and tissue peripheral to the surgical site and to follow a vessel even beyond the incision. The transducer section is completely encapsulated in a rubberlike material which electrically insulates the transducer from the patient, enables the probe to be easily sterilized, and further provides an inherent standoff between the transducer and the contact surface of the probe. Thus, the transducer can be focused immediately at the skin line of the organ or vessel which is in contact with the probe. The probe can be easily assembled by providing termination assemblies for attaching coaxial cable conductors to the printed circuit board assembly of the probe.
摘要翻译：描述了一种术中超声换能器探针，其包括类似于小腿和脚的手柄部分和换能器部分。两个部分相对于彼此是钝的，使得医生可以在保持和操纵探针的同时继续清楚地观察手术部位。换能器部分远离其附接点到手柄部分的延伸导致脚的脚趾可插入到未矫正的组织中，使得外科医生能够超声检查外科手术部位周围的器官和组织，并且跟随血管甚至超出切口。换能器部分完全封装在橡胶状材料中，使得换能器与患者电绝缘，使得探针易于消毒，并进一步提供换能器与探针的接触表面之间固有的间隙。因此，换能器可以立即聚焦在与探针接触的器官或血管的皮肤线上。可以通过提供用于将同轴电缆导体连接到探针的印刷电路板组件的终端组件来容易地组装探针。
