    摘要: A system and method for controlling the heat of an ultrasonic transducer is disclosed. In the presently preferred embodiments, the system and method controls the temperature of the transducer by changing operating system parameters based on feedback from temperature sensing elements placed in the transducer. The chosen mutable system parameters may be preset by the construction of the ultrasonic system, under the control of the ultrasonic system user, or a combination of the two. In several exemplary embodiments, the one or more mutable system parameters are altered by an amount proportionate to the difference between the current temperature and a preferred operating temperature. In another exemplary embodiment, the system switches to a lower power imaging mode when the temperature feedback indicates a threshold temperature has been reached.

    摘要: A method and system for generating a three-dimensional (3D) qualitative display (10,110,144) in an ultrasound system (30) include generating a first and a second two-dimensional (2D) slice (102,106,108) from a 3D data set of a 3D volume view of an ultrasound image. The first and second 2D slices (102,106,108) define a first and second plane of the 3D volume view along a first axis, wherein the second plane is orthogonal to the first plane. First and second border tracings (122,124) are generated around a portion of interest in the first and second 2D slices (102,106), respectively. A display (48) then displays (10,110) representations of the first and second border tracings within a single 3D view (10,128,130,146), wherein the 3D view provides an indication of alignment distortion of the first and second border tracings along the first axis. In one embodiment, at least one additional 2D slice defines an additional plane of the 3D volume view along a second axis, orthogonal to the first and second planes. Furthermore, at least one additional border tracing generated. The display (48) then further displays the at least one additional border tracing along the second axis within the single 3D view for providing an indication of alignment distortion of the first, second, and at least one additional border tracing along the first and second axes.

    摘要: An ultrasonic imaging system produces a sequence of images of the heart during a cardiac cycle. The images are analyzed to determine the motion, displacement, or change in size of segments of the myocardium. In a preferred embodiment the values determined are radial, longitudinal, or circumferential myocardial strain values. The displacement of the myocardial segments may be tracked during the cardiac cycle by speckle tracking or border detection. The motion, displacement, or change in size values for the segments are analyzed to produce a recruitment curve and anatomical display showing the relative times of recruitment of the different segments in the contractile and relaxation motion of the heart. Participation in and achievement of full recruitment may be determined by comparison against an initial recruitment threshold criterion and against a predetermine maximal recruitment milestone level.

    摘要: An ultrasound system for planning a surgical implantation of an implantable device produces two or three dimensional ultrasound images of the site of the surgical implantation. An image of a sizer for an implantable device comprises a virtual sizer which is scaled to the scale of the anatomy in the ultrasound image. A user manipulates the virtual sizer on the display in relation to the anatomy in the ultrasound image to ascertain whether the virtual sizer, and hence its corresponding implantable device, fits the patient's anatomy. In place of the anatomical ultrasound image a model of the anatomy can be produced from the ultrasound image data and used for sizing. When sizing is done with 3D ultrasound images, the fit of the virtual sizer and the anatomy can be studied by rotating and tilting the two images together. Imprecision in the fit of the virtual sizer and anatomy can be display with highlighting.

    摘要: An ultrasonic diagnostic imaging method and system are described for detecting abnormalities in the synchronicity of heart wall stimulation. Points on opposite sides of a chamber of the heart are identified in a starting ultrasound image, then tracked through at least a portion of the heart cycle. The changing positions of lines extending between pairs of the points are accumulated and displayed in a color kinesis display in which each color depicts the location of a line at a particular point in the cardiac cycle. In an illustrated example the points are tracked through the cardiac cycle by speckle tracking of the speckle pattern of the adjacent myocardial tissue, tracking specific anatomy, or tracking tissue texture.
