EAI Interactive Anounces CardioViewer 3D CD-ROM

GROUND-BREAKING DIGITAL DISSECTION OF HUMAN CARDIOVASCULAR SYSTEM FOR
MEDICAL STUDENTS AND SURGEONS

AMES, Iowa -- May 13, 1996 -- EAI Interactive, the multimedia division of
Engineering Animation, Inc. (NASDAQ: EAII), today announced the
availability of CardioViewer 3D, an interactive CD-ROM title that allows
the study of cardiovascular function and procedures for students and
surgeons.

Published by international health science publisher Mosby-Year Book, Inc.,
CardioViewer 3D, is a low-cost, high-content multimedia tool for studying
detailed cardiac anatomy and cardiac structures in a realistic,
interactive context. Based on detailed medical images from an actual human
cadaver, CardioViewer 3D presents a useful alternative to dissections of
real cadavers. In addition, the CD-ROM includes footage of diagnostic
imaging techniques such as cineangiography and echocardiography and live
video footage of open heart surgery.

"This is the first CD-ROM that enables students or surgeons to study the 3D
anatomy and physiology of the heart and at the same time view a movie of a
diagnostic imaging sequence from a clinical setting," said Marty
Vanderploeg, EAI's executive vice president and chief technology officer.
"The ability to correlate 3D anatomy with clinical images on the same
screen makes CardioViewer 3D a revolutionary teaching tool."

"EAI's superior technology is taking higher education to a new level, "
said Michael Ackerman, project officer of the National Library of
Medicine's (NLM's) Visible Human Project which provided the original data
upon which CardioViewer 3D is based. "To be able to view actual images
from a human cadaver and interact with those images in a virtual
environment is a phenomenal teaching tool and an important milestone in
the medical community. Further, CD-ROMs such as CardioViewer 3D may
provide viable, infinitely-reusable alternatives to actual dissection."

CardioViewer 3D comprises three main sections: an animated, interactive
model of a beating human heart, with both external and sectional views; a
section on the Visible Human Project which utilizes volume renderings and
digital dissection of the heart; and a clinical cardiology section with
animations and actual footage of diagnostic imaging of the normal and
diseased heart. The beating heart model and digital dissections use EAI's
proprietary 3D Viewer technology, which allows viewing of the heart
through interactive rotation and positioning of cutting planes to study
cardiac functions from different perspectives. 3D Viewer also provides
interactive identification of any structure from any view. Additionally,
CardioViewer 3D includes audio pronunciation of structures, providing yet
another unique aspect of teaching through multimedia.

With CardioViewer 3D, students can display both clinical movies and 3D
Viewers of anatomy simultaneously. By having multiple windows open at the
same time, students can identify anatomy in the clinical movies as well as
correlate function between the animations and clinical movies.

CARDIOVIEWER JOINS GROWING LINE OF EAI INTERACTIVE BIOMEDICAL TITLES

CardioViewer 3D is the latest in an expanding line of multimedia biomedical
titles produced by EAI Interactive in partnership with leading publishers.
In producing these titles, EAI Interactive has leveraged the
groundbreaking cross-sectional images of a human male cadaver that were
generated by the National Library of Medicine's (NLM's) Visible Human
Project. EAI developed proprietary algorithms to perform direct 3D
volume-renderings and to create surface models of the Visible Human
dataset. As a result, EAI Interactive's multimedia titles are extremely
accurate, detailed and realistic representations of human anatomy. Other
EAI Interactive titles include The Dynamic Human CD-ROM, an illustrated 3D
guide to anatomy and physiology released in December 1995 by Mosby-Year
Book, and the soon-to-be-released The Dissectable Human, an interactive 3D
volume-rendered anatomical atlas of the human body encompassing real human
data.

PRICE AND AVAILABILITY

CardioViewer 3D CD-ROM is scheduled to be available in May 1996 for $19.95.
The Dissectable Human CD-ROM is scheduled to be available in May 1996 for
$49.95. The Dynamic Human CD-ROM is currently available for $49.95. All
titles run on both Windows and Macintosh systems.
