We will discuss analytical methods used in developing the design of a scanner in use today. The key points to be covered deal with methods of analysis of array data, the interaction of transmit and receive beams with clinically relevant targets, and how this interaction is used in the generation of clinically useful images. The means by which these analytical methods contribute to a system design and the trade-offs involved are reviewed. The last several years have seen steady migration of functionality into software; this has enabled significant miniaturization of scanners. The impact of this on system design and the size of ultrasound scanners of the future will be discussed.

Short Course 1B (1:00 P.M. - 5:00 P.M., Sunday, November 2, 2008):

Course Title:  Ultrasound Elastography: Quantitative Approaches

*Jeffrey Bamber and **Paul Barbone, *Institute of Cancer Research and Royal Marsden Hospital, UK. **Boston University, USA.

Course Description: There is evidence that ancient cultures extending back thousands of years used palpation to assess the mechanical properties of tissues, and thus detect and characterise disease or injury. Simple palpation continues to be of value in modern medicine, both practiced by doctors and as a technique for self-examination, but palpation is limited to a few accessible tissues and organs, and the interpretation of the information sensed by the fingers is highly subjective. Ultrasound elastography aims to display images that are related to a broad range of parameters that describe the spatial and temporal variations in tissue viscoelasticity. It does so by processing time-varying echo data to extract the spatial and/or temporal variation of a stress-induced tissue displacement or strain. In recent years the method early form has emerged as a real-time imaging modality available as an option on several commercial ultrasound systems, and is starting to prove clinically valuable, for example in breast cancer diagnosis. Nevertheless, in its present form it remains a strongly subjective technique and continues, as with palpation, to require considerable interpretive skills to be learnt. There are good reasons to believe that a more quantitative and objective analysis will lead to clinically more valuable measures of tissue composition, function or state, with images that are easier to interpret. This short course will outline some of the limitations and pitfalls of current elastographic methods, and will then introduce the opportunities for, potential value of and challenges for making elastography more quantitative. It will then review work on modeling tissues and their mechanical behavior, the fundamentals of ultrasound elastographic experimental techniques required for quantitative imaging, the use of static, vibrational and impulsive loads, the inverse methods for measurement and image reconstruction, methods for stress measurement, and shear wave propagation methods. This will lead to a discussion of the likely consequences for medical applications and future instrumentation. Examples of results will be presented for a range of medical application areas and for various mechanical characteristics such as shear modulus, nonlinearity, anisotropy, friction at mechanical discontinuities, as well as properties that determine viscoelastic and poroelastic behavior.

The materials discussed during this course cover most aspects of physical principles and applications of high-resolution acoustic microscopy and reflects the modern research status in this field. Included are different topics in physical acoustics, ultrasound, solid state physics, materials characterization and nondestructive evaluation. Special attention will be paid to the principle and application of several types of scanning acoustic microscopes for medical and biological use. Progress in digital measurement and pulse technology has remarkably upgraded the performance of these types of microscopes and this will be described within the course. The sound speed microscope which conventionally used tone-burst and analog phase detector was improved in accuracy, stability and operation ability.  It can be used for characterization of tissue sliced and mounted on a slide glass.  It can visualize not only acoustic impedance but bulk modulus, attenuation constant and density.  The acoustic impedance microscope can visualize the acoustic impedance of a cross section in touch with a plastic substrate by transmitting an acoustic beam from the rear side of the substrate.  This type of microscopy has an advantage that the measurement can be performed in vivo, introducing no contamination into the target system.  With a wide frequency range up to 400 MHz, both types of microscopes can observe with a special resolution as fine as cell structure. Discussed will be the principle of the sound speed and acoustic microscopes driven by a wide band pulse and several examples of observation of cerebella tissue and cultured cells will be shown. In addition, there will be a presentation of recent results in acoustic microscopy technology development achieved by Honda Electronics (Japan) and Tessonics (Canada). The detail of the hardware and software of those microscopes that are commercially available will be described.  The prototype microscopes have been improved a lot after being commercialized. The hardware, software and biomedical applications of these microscopes will be described with a large number of examples as additional illustrations. This course will conclude with an overview of the future perspectives of the general principles of microscopic observation using various ultrasound waves as well as the most promising future applications.

Course Description: The use of ultrasound in medicine is now quite commonplace, especially with the recent introduction of small, portable and relatively inexpensive, hand-held diagnostic imaging devices. Moreover, ultrasound has expanded beyond the imaging realm, with methods and applications extending to novel therapeutic and surgical uses. These applications broadly include: Tissue ablation, acoustocautery, body contouring, site-specific and ultrasound mediated drug activity, extracorporeal lithotripsy, and the enhancement of natural physiological functions such as wound healing and tissue regeneration. A particularly attractive aspect of this technology is that diagnostic and therapeutic systems can be combined to produce totally non-invasive, image-guided therapy. This general lecture will review a number of these exciting new applications of ultrasound and address some of the basic scientific questions and future challenges in developing these methods and technologies for general use in our society. We shall particularly emphasize the use of High Intensity Focused Ultrasound (HIFU) in the treatment of benign and malignant tumors as well as the introduction of acoustic hemostasis, especially in organs which are difficult to treat using conventional medical and surgical techniques.

Course Title:  CMUTs: Theory, Technology, and Applications

B.T. Khuri-Yakub, Ömer Oralkan, and Mario Kupnik, E.L. Ginzton Laboratory, Stanford University, USA.

Course Description: This course provides basic knowledge and understanding of capacitive micromachined ultrasonic transducers (CMUTs) and their applications. After a short background discussion of previous implementations of capacitive ultrasonic transducers, we will provide all the information necessary for the successful design of a CMUT: The simple parallel plate capacitor transducer and its electrical equivalent circuit model will be explained in detail, including the derivation of all essential design equations, and the theoretical device performance limits. An approximate analytical model, that better represents the realizable membrane of a CMUT, will be presented next. By discussing a possible beyond pull-in point operation regime (collapse mode), the motivation for a more sophisticated finite element model is given, and the key techniques of finite element analysis based CMUT designs are explained and demonstrated using brief examples. After explaining these techniques, we compare the two main domains in which a CMUT can operate, i.e. as an airborne device and in immersion. Only for immersed operation the periodic structure of a CMUT array needs to be considered to minimize parasitic cross-talk effects. Two acoustic cross-talk modeling techniques will be discussed for that purpose. Then, the two main CMUT fabrication techniques, i.e. sacrificial release and direct wafer bonding, are explained and compared to each other. Next, we discuss device characterization which will cover optical displacement, electrical input impedance, then acoustical measurements of output pressure, receive sensitivity, impulse response and dynamic range. Then, non-conventional CMUT designs are addressed, such as piston CMUTs, CMUTs with various cell-shapes, and CMUTS with non-uniform cavities. Besides an overview of several CMUT applications, we conclude the course by giving two detailed design examples, one for an airborne device for chemical/biological sensing applications and one for medical imaging applications. A comprehensive copy of the presentation will be made available to the course participants.

Course Title:  Time Reversal Acoustics

Mathias Fink, École Supérieure de Physique et de Chimi de la Ville de Paris, France.

Course Description An acoustic Time Reversal Mirror (TRM) refocuses an incident acoustic field to the position of the original source regardless of the complexity of the medium between this "probe" source and the TRM. TRM's have now been implemented in a variety of physical scenarios from MHz ultrasonics with order centimeter aperture size to hundreds/thousands of Hz in ocean acoustics with order hundred meter aperture size. Common to this broad range of scales is a remarkable robustness exemplified by observations at all scales that the more complex the medium between the probe source and the TRM, the sharper the focus. The potential for applications in many areas of acoustics is quite high. The objective of this course is to provide the acoustical physics overview and description of the experimental implementation of time reversal and phase conjugate processes as related to ultrasonics and imaging, nondestructive testing, medical ultrasonics, propagation in random media, room acoustics, waveguides, and ocean acoustics.

Mathias Fink is a Professor of Physics at the École Supérieure de Physique et de Chimi de la Ville de Paris (ESPCI) and at Paris 7 University (Denis Diderot), France. In 1990 he founded the laboratory Ondes et Acoustique at ESPCI. In 2002, he was elected at the French Academy of Engineering and in 2003 at the French Academy of Science. His area of research is concerned with the propagation of waves in complex media and the development of numerous instruments based on this basic research. The domain of applicability of these instruments is vast: medical imaging and therapy, non-destructive testing, underwater acoustics, seismology, telecommunications and instrumentation. He has a long history of collaboration with industry. He works with companies in a wide variety of sectors including medical, aeronautics, underwater acoustics, nuclear, metallurgy, and instrumentation. He pioneered many innovative approaches based on time-reversal mirrors and on the development of a new imaging concept: transient elastography. He has over 40 patents, 300 publications, edited 2 books and supervised 48 PHD students.

Short Course 4C (6:00 P.M. - 10:00 P.M., Sunday, November 2, 2008):

Course Title:  Acoustical Near-Field Imaging

Walter Arnold, Fraunhofer Institute for Non-Destructive Testing, Saarbrücken, Germany.

Course Description: Acoustical imaging modes can be classified into near-field, focusing techniques, and holographic techniques. This four hour course discusses, in particular, near-field imaging modes. Examples are ultrasonic force microscopy, atomic force acoustic microscopy, and impedance imaging such as Fokker-bond tests. Their resolution in terms of the antenna size (i.e. probe size) and wavelength employed both at the surface and in the depth of the component to be imaged, are discussed. Besides the underlying contrast mechanism, the course also covers the signal analysis and capture techniques. Finally a comparison is made to classical acoustical imaging based on focusing probes, holographic imaging, and phased arrays principles. The examples are underlined by applications in non-destructive testing.

Walter Arnold has authored and co-authored about 300 publications (200 in Non-Destructive Testing, others in Solid State and Applied Physics and Materials Science), holds 10 patents and has edited two books besides organizing several conferences both on a national and international level. He has guided 140 master theses and 27 PhD theses. Dr. Arnold was the head of the research department at Fraunhofer-Institute for Non-Destructive Testing (IZFP) in Saarbrücken, Germany until his retirement at the end of 2007. Parallel to his position at the IZFP, Dr. Arnold was and still is professor of Materials Science at the Saarland University, Dept. Materials. He is an Honorary Fellow Indian Institute of Non-Destructive Testing, Fellow Institute of Physics, London.
