Invited Presentation: 099 THE MODERN ULTRASOUND RESEARCH INTERFACE. Reza Zahiri Azar 1 , Corina Leung 1 , Kris Dickie 1 , Laurent Pelissier 1 . 1 Ultrasonix Medical Corporation, Richmond, BC, CANADA. Ultrasound is one of the most inexpensive and safest methods to capture real–time medical images. These advantages have made it popular in many medical applications as well as numerous research studies. As a result, having access to its data for research purposes has gained a lot of interest in the past few decades and has been shown to enable new imaging techniques such as elastography and photo–acoustic imaging. Furthermore, having control over all its internal parameters has also proven to be critical in several advanced imaging modes such as ultrafast imaging and angular compounding. Previous to system designs like the Ultrasonix, research was carried out mainly by using frame grabbers to obtain the analog video signal from the ultrasound, or very large scale systems that could be digitally programmed, but remained immobile. With the miniaturization of technology, and the ability to use more programmable components, the ultrasound market has seen more functional and portable devices become available to researchers. Further, a proper research interface is required that makes use of modern software development techniques to efficiently provide data for researchers. Since the introduction of the research package in 2001, Ultrasonix has always tried to improve the experience of the researchers by allowing them to tailor the system to their custom working environment while still maintaining clinical integrity of using a robust medical device. Its PC–based architecture has drastically simplified the acquisition of ultrasound data, allowing the researcher to have access to these data at every step of the signal processing, starting from pre–beamformed ultrasound data up to the final ultrasound image, in both off–line and real–time modes, on the system itself as well as over the internet. Its programmable hardware and open architecture have also allowed the user to reconfigure all the imaging parameters including all the transmit and receive parameters as well as adjusting all the internal parameters according to their custom applications. Its open architecture has allowed the researcher to integrate his work directly into the system as additional plug ins, thus eliminating the need for additional hardware. Its clinically driven interface has also allowed the researcher to collect data in the clinical environment directly. In addition, custom ultrasound transducers can be easily integrated onto the device allowing researchers to use the system for many different applications. In this presentation, we will review some of the latest technologies and systems that are developed using Ultrasonix research devices from more than 200 research sites around the world. We will also reveal some works–in–progress technologies that may be implemented into research devices in the near future to help further improve the experience of the researchers. 72 Ultrasonix Begins 1 st Patent Approved 2000 2001 2003 2005 2009 2010 2011 <strong>2012</strong> 1 st Research Box Sold to UBC ES500RP SonixRP SonixTouch Research SonixDAQ Research Device Time–Line, Ultrasonix Medical Corporation.

Invited Presentation: 100 A NEW PARADIGM IN ULTRASOUND IMAGING. J Souquet 1 , J Bercoff 1 . 1 Supersonic Imagine, Aix–en–Provence, FRANCE. Background: Today there is an intrinsic limitation regarding frame rate acquisition of ultrasound information coming from the body. This limitation is due in part to the speed at which the ultrasound wave propagates in the tissue but also to the architecture of every system on the market whereby the somewhat sequential nature for data acquisition limits the speed at which images can be displayed. The new paradigm consists of the creation of a new ultrasound system architecture with heavily parallelized acquisition where the receive beamformer is achieved in software. With such a unique architecture, we have demonstrated acquisition frame rate of more than 5000 frames/sec. Such architecture is an enabler of new approaches to ultrasound: speed of sound optimization, transmit synthetic flat focus, etc. Advantages: Some of those advantages will be demonstrated; however one of the most interesting approaches is to leverage such frame rate for transient elastography. Transient elastography is a unique patented approach to elastography (assessment of tissue elasticity) totally user skill independent. The new approach consists of sending a shear wave into tissue and assess the speed at which the shear wave propagates in real time. Shear wave velocity is directly proportional to the square root of the Young’s modulus, therefore, by inverse problem knowing the shear wave velocity, we can derive the elastic properties of tissues and provide a full 2D map of tissue stiffness. Presentation: We will demonstrate how one can generate shear wave propagation in tissues, why ultra fast frame rate acquisition is a must and share clinical results obtained on different organs like breast, thyroid, liver, prostate and MSK.
