Embodiment Construction

[0014] Ultrasound raw channel data is compressed for sending to a processor or system for ultrasound imaging. Any set of basis functions can be used, such as Fourier basis. Compression is obtained in the lateral dimension or across the array, allowing the use of conventional delay-sum beamformers. When the amount of frequency domain data representing the channel data or the number of frequency domain 'beams' is smaller than the number of channels, effective compression is obtained compared to directly transmitting the raw channel data. Can provide 3:1 or more raw channel data compression. Common hardware (ie, a delay-sum beamformer) performs transversal encoding of the raw channel data to reduce the total amount of raw channel data sent to the computer over the PCIExpress or other bus.

[0015] This reuse of existing hardware may keep development time and costs low, and / or allow the use of new beamforming techniques, such as frequency domain beamforming applied in software. ...

Abstract

Ultrasound beamformer-based channel data compression allows for software-based image formation. To increase the amount of data transferred, ultrasound beamformer-based channel data compression is provided. A beamformer is used to compress instead of or in addition to traditional beamformation. The compression reduces the data bandwidth while allowing reconstruction of the original channel data.

Description

technical field [0001] This embodiment relates to medical diagnostic ultrasound imaging. In particular, channel data compression is provided for ultrasound imaging using software. Background technique [0002] As computer processing power has increased, ultrasound systems have increasingly moved hardware signal processing functionality into software. Software-based signal processing facilitates flexible development, better maintainability, cost, and rapid experimentation. A major problem facing software-based ultrasound systems is the drive of large amounts of single-element, raw channel data from the ultrasound front-end to computer memory for processing. When the system channel count is large (eg, 128 elements or channels), the transfer data rate can be very high and challenges the maximum data rate of even the most advanced state of the art computer buses. To handle such large transfer rates, additional or custom hardware could be used, but this defeats the main purpos...
