  • Publication number: 20050283079
    Abstract: In one embodiment, an ultrasound system is provided that includes a probe having a 2D array of transducers for acquiring ultrasound information along a plurality of scan lines through an object in real time. The scan lines are arranged to define volumetric data corresponding to a volume of interest (VOI) in a subject or patient. One such VOI may include the human heart or some portion of the human heart. The system includes a beamformer configured with scan parameter values that define the scan lines. An image buffer stores multiple data volumes acquired over time that are successively retrieved and processed by a display processor.

  • Publication number: 20050281444
    Abstract: A protocol-based ultrasound method is provided. The ultrasound method provides a template comprised of cells. Each of the cells contain scan parameters defining a scan sequence for acquisition of ultrasound images along one or more scan planes through an object. Prior to scanning the object, parameter values for the scan parameters associated with cells in the template are entered to define the scan sequences along at least two scan planes. The object is scanned with an ultrasound probe to automatically and successively acquire ultrasound images along at least two scan planes based on the parameter values for the scan parameters in the cells. The method displays ultrasound images of an object that is changing states in accordance with a protocol. Each of the ultrasound images is acquired along a corresponding scan plane through the object. A collection of ultrasound images is provided. Each of the ultrasound images is acquired along an associated scan plane while the object is in an associated state.

  • Publication number: 20050110793
    Abstract: Graphics processing circuitry includes a graphics processing unit, a system interface coupled to the graphics processing unit, and a graphics memory coupled to the graphics processing unit. The graphics memory holds an image data block, a vertex data block, and rendering plane definitions. The image data block stores image data entries for at least one ultrasound imaging beam and the vertex data block stores vertex entries that define rendering shapes. The graphics processing unit accesses the image data entries and vertex entries to render, from back to front or back to front using alpha compositing, a volume according to the rendering plane definitions.

  • Publication number: 20050090745
    Abstract: A medical imaging system includes an image sensor that receives imaging signals from a region of interest, a memory coupled to the image sensor, and a processor coupled to the memory. The memory stores image data derived from the imaging signals for first and second sub-regions of the region of interest acquired during a first and second occurrence of a physiologic cycle. The processor initiates display of the first image data while the second image data is being acquired and initiates display of the first image data joined with the second image data after the second image data is acquired.
