ABSTRACT: Diagnostic ultrasound has become a standard tool in the delivery of health care. Although some work was carried out at least as early as the 1940s, medical imaging with ultrasound grew from a modest novelty in the early 1970s to become the widely used and still rapidly growing diagnostic modality of today. In this tutorial lecture we will illustrate the use of ultrasonic imaging with the aid of video tapes and large screen projection of representative diagnostic studies. Some of the physics and engineering underlying the generation of clinical images will be reviewed at an intuitive, non-mathematical level. We will also highlight some of the advantages and limitations of ultrasound in comparison with alternative diagnostic modalities. Specific applications used to diagnose heart disease will provide opportunities to illustrate ultrasonic imaging of the beating heart. We will show real-time two dimensional ultrasonic images of the heart with superimposed color encoded visualizations of Doppler-based estimates of blood flow in the cardiac chambers, which have become the standard for the diagnosis and management of most forms of heart disease

Short Course on

"Smart Structures and Microelecctromechanical Systems (MEMS)"

Instrcutors: Vijay Varadan and Vasundara Varadan
Alumni Distinguished Professors of Engineering Science and Mechanics and Electrical Engineering
Co-Directors of the Center for the Engineering of Electronic and Acoustic Materials
Pennsylvania State University
Friday, 20 June (1:00 p.m. to 5:00 p.m.) and

In recent years, the field of sensing and control of noise and vibration in underwater structures, civil structures, aircraft and helicopters with electronic materials such as piezoelectric and ferroelectric ceramics, films and polymers, and MEMS (MicroElectroMechanical Systems) devices attracts researchers from various disciplines. The objective of this course, thus, is to provide an interdisciplinary flavor with an introduction of smart materials, smart electronics, and MEMS to design and develop cost effective, lightweight and reliable microsensors, microprocessors and actuators for noise suppression and vibration reduction in aircraft cabins, control of radiated noise in underwater structures, flow induced noise in helicopters, etc

The registration fee is $250 and covers attendance, instructional materials and coffee breaks. Only those who have registered by 2 June will be guaranteed receipt of instructional materials to the course. There will be a $50 discount for reservations made prior to 2 May. Full refunds will be made for cancellations prior to 2 June. Any cancellation after 2 June will be charged a $25 processing fee. course.

Short Course on

"Design of Acoustic Materials"

Instrcutor: Bruce Hartmann
Polymer Science Group
Carderock Division
Naval Surface Warfare Center
Instrcutor: Jacek Jarzynski
George W. Woodruff School of Mechanical Engineering
Georgia Institute of Technolog
Friday, 20 June (2:00 p.m. to 5:00 p.m.) and
Saturday, 21 June (9:00 a.m. to 5:00 p.m.)
Registration Fee: $250

In this course, the phrase "acoustic materials" includes both the viscoelastic material used and the configuration the viscoelastic material is used in. Thus, there are two parts to the course: the first part is on intrinsic viscoelastic material properties and how these properties are related to molecular structure, and the second part is on the use of these materials in a configuration to enhance sound absorption or decoupling, such as a coating of the material with inclusions, or a wedge of the material in air. The "design" includes both the molecular or chemical arrangement and the physical arrangement such as the thickness of the viscoelastic layer and the size of the cavities. The goal of the course is to provide sufficient background to design an acoustic material for a wide variety of applications, involving both water-borne and air-borne sound.

The registration fee is $250 and covers attendance, instructional materials and coffee breaks. Only those who have registered by 2 June will be guaranteed receipt of instructional materials. There will be a $50 discount for reservations made prior to 2 May. Full refunds will be made for cancellations prior to 2 June. Any cancellation after 2 June will be charged a $25 processing fee.

Undergraduate Research Poster Session

The ASA Committee on Education in Acoustics is sponsoring an undergraduate research poster session. Papers for this poster session should be submitted following the abstract submission guidelines in Section 2. For additional information contact Vic Sparrow of Penn State. Telephone: (814) 865-3162, FAX: (814) 863-7222, E-mail: sparrow@helmholtz.psu.edu

Plenary Session, Awards, Fellows' Luncheon and Social Events

Complimentary buffet socials with cash bar will be held early on Tuesday and Thursday evenings. The Plenary session will be held on Wednesday afternoon where Society awards will be presented and recognition of Fellows will be announced. A Fellows' Luncheon will be held on Thursday; ASA Fellows may purchase tickets at the meeting.

Exhibits

A equipment exhibition for the joint meeting will be held at the Penn State Conference Center, 16--18 June. The exhibition will include active noise control systems, computer-based instrumentation, sound level meters, sound intensity systems, signal processing systems, devices for noise control and acoustical materials. Organizations interested in exhibiting should contact: Richard Peppin, 5012 Macon Rd., Rockville, MD 20852, Tel.: 301-984-3375; E-mail: rpeppin@aol.com.
