Embodiment Construction

[0022] The present invention relates to ultrasonic diagnostic systems such as those used in medical diagnostic systems in medical human and animal applications. Some aspects of the invention are understood in conjunction with WO / 2014 / 125371 , which corresponds to PCT / IB2014 / 000281 , which is incorporated by reference into this application. The invention can also be used for non-destructive testing / evaluation (eg, assembly line testing, airframe testing, turbine blade testing, bridge and structural testing, manufacturing testing of metal work rolls, for example). Ultrasonic testing is a type of non-destructive testing commonly used to find flaws in materials and measure the thickness of objects. Frequently frequencies from 1 to 50 MHz are used, but other frequencies are used for specific purposes. Inspection can be manual or automated and is a critical part of the modern manufacturing process. Most metals as well as plastics and aerospace composites can be inspected. Lower f...

Abstract

An ultrasound beamformer architecture performs the task of signal beamforming using a matrix of analog random access memory cells to capture, store and process instantaneous samples of analog signals from ultrasound array elements and this architecture provides significant reduction in power consumption and the size of the diagnostic ultrasound imaging system such that the hardware build upon this ultrasound beamformer architecture can be placed in one or few application specific integrated chips (ASIC) positioned next to the ultrasound array and the whole diagnostic ultrasound imaging system could fit in the handle of the ultrasonic probe while preserving most of the functionality of a cart-based system. The ultrasound beamformer architecture manipulate analog samples in the memory in the same fashion as digital memory operates that can be described as an analog store-digital read (ASDR) beamformer. The ASDR architecture provides improved signal-to-noise ratio and is scalable.

Description

[0001] Related references [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 079,855, filed November 14, 2014, entitled "Analog Random Access Memory Array Based Ultrasound Beamforming System and Method." technical field [0003] The present invention relates to ultrasound beamforming, and more particularly, the present invention relates to an Analog Store Digital Read (ASDR) ultrasound beamforming system and associated method. Background technique [0004] Analog memory devices are successfully used in a large number of technical fields such as digital storage oscilloscopes, X-ray detectors and high energy particle tracking applications. Early pioneers of this technology can be traced to Fast-In-Slow-Out (FISO) based digital oscilloscopes and waveform capture devices such as those described in U.S. Patent Nos. 4,271,488 and 4,833,445, which are incorporated by reference in this application. The '445 patent describes a fast, high-resolu...
