    摘要： A system for dynamic optimization of gain and contrast in ultrasound imaging includes an image processor module programmed to dynamically estimate a correction profile in real-time and apply the correction profile to adjust a gain and contrast of image frame data sets. The image processor module is programmed to identify tissue and background regions in an image frame data set, determine an image intensity for each of the tissue and background regions, and formulate a gain profile based on the image intensity of the tissue region to compensate the gain variation of an image. The image processor module is further programmed to calculate an image contrast metric based on the image intensity of the tissue and background regions, and modify a gray map of the image frame data set based on the image contrast metric to adjust the contrast of an image displayed on the display system.

    摘要： A wireless ultrasound imaging system includes plural probes, at least one access point device, and a processing subsystem. Each of the probes has at least one transducer element that is configured to emit ultrasound pulses into one or more imaged bodies and receive echoes of the pulses. The probes are configured to generate ultrasound data based on the echoes and to wirelessly transmit the ultrasound data. The access point device is configured to wirelessly receive the ultrasound data from the probes. The processing subsystem is communicatively coupled with the at least one access point device. The processing subsystem receives the ultrasound data from the probes and creates one or more images based on the ultrasound data. In one aspect, a plurality of the probes is configured to concurrently acquire the ultrasound data.

    摘要： Systems and methods for determining scan parameters to be used during image acquisition are provided. Values of imaging effects can be input using user controls accessible from a user interface. A processor can determine scan parameters to be used during image acquisition based on the input imaging effect values. The determined scan parameters can be displayed using the user interface. Values of imaging effects and potential ranges of values of imaging effects can be constrained based on selected values of other imaging effects. Imaging effects can include image resolution, image penetration, frame rate and/or color flow sensitivity. Scan parameters can include: line density, number of focal zones, frequency, dynamic range, pulse repetition frequency, and/or number of compounding angles. An ultrasound imaging system can be used to acquire images using the determined scan parameters.

    摘要： An ultrasound system operating on a personal computer architecture comprising multiple processors controlled to operate in parallel to share ultrasound operations of the system. The multiple processors are controlled by software to share the operations associated with system setup, system control, scanning, data acquisition, beamforming, user interface service, signal processing, and scan conversion. The ultrasound system utilizes management software which divides operations associated with each function (such as signal processing and scan conversion) into parallel sub-operations or tasks. Each task is assigned by the operating system to a CPU. Any of the CPUs may be capable of performing any of the tasks. The CPUs operate in parallel to carry out the assigned tasks. Once all of the CPUs have completed the assigned tasks, the system may serially advance to the next ultrasound function.
