Abstract: A method and apparatus are provided for interpolating image lines from ultrasonically obtained scanlines of an image region. The interpolated lines are preferably formed one-quarter and three-quarters of the distance between each pair of received scanlines by combining weighted samples of the adjacent scanlines in proportion to their distances from the interpolated lines. The received scanlines are preferably formed by a beamformer which samples the received lines at quadrature phases of the scanhead center frequency and filters the samples by combining successive samples of a related phase. The image lines are scan converted by computing a grid of weighted values between each pair of image lines, and using the closest value for each pixel in the ultrasound image.

Abstract: An ultrasonic diagnostic imaging system is provided with a personal computer platform which processes digital echo signals and produces ultrasonic image signals for display. The expansion bus structure of the personal computer platform accommodates ancillary processors such as beamformer cards, digital signal processing cards, video cards, and network cards which may be necessary or desirable for the ultrasound system. In a preferred embodiment the digital signal samples produced by a beamformer connected to the expansion bus are processed for display by software executed by the CPU of the personal computer platform. A preferred software architecture for the personal computer based ultrasound system consists of multiple object oriented software tasks, executing under a realtime, multitasking operating system which is both efficient and robust. Performance upgrades of the entire ultrasound system are effected by simple replacement of the CPU with a higher performance CPU, thus providing continual ultrasound system performance improvements in consonance with the evolution of personal computer CPU technology.
