The objective of this paper is not to present a catalog of current or potential applications of computer graphics in medicine, but rather to raise some basic key issues for consideration. The six theses which I am exploring are:

1. Iconic Communication ...

In 1964 on Project MAC at MIT, Levinthal and Langridge first applied interactive computer graphics to molecular model building (1, 2). Since then a number of laboratories have developed computer graphics systems to suit their particular needs (3, 4, 5, ...

A review of on-going projects employing an interdisciplinary approach is presented. This approach is the applicability of computer graphics, fluid dynamics and numerical analysis techniques to hemodynamic problems in medicine. It has been shown to be ...

The present investigation applies fluid dynamics principles and numerical analysis techniques in an attempt to study stress distributions in blood caused by the motion of the occluder in a prosthetic heart valve. An interactive computer graphics program ...

A subject walking in front of a coded background is photographed with a high speed movie camera. For greater accuracy, the camera is moved parallel to the subject at his walking speed. The successive film frames are analyzed by a flying spot scanner ...

KINSYN is an interactive general purpose computer system for the kinematic synthesis and analysis of mechanisms. It is applicable to kinematics problems ranging from the synthesis of spacecraft antenna deployment mechanisms to the design of folding high ...

This paper describes a system designed around a small laboratory computer directed toward the task of quantitating ventricular arrhythmias in support of pharmacologic research. This class of disorders of cardiac rhythm is so designated because the site ...

Whether one is talking about the verbal or graphic aspects of a computer mediated tutorial, there are two prime considerations. (1) How easy is it for the medical teacher to input the information? (2) How closely does the interaction with the student ...

The size of the body of medical literature is vast and growing at a rapid rate. The National Library of Medicine collection contains about two million items and at the present rate of growth will double in about 7 years.

Attempts to improve the access ...

In the first part of my talk I will describe the operation of a symbolic graphics computer system; next, I will show how some models can be implemented by using this system, and finally I want to discuss techniques for establishing the validity of ...

This paper presents a summary of the experience gained in operating a medical information system in a rural private physician's office. In particular, data is presented on this operational system which should be helpful to designers for defining the ...

One begins increasingly to hear the phrase “out of control” in reference to rising health care costs. Whether or not the health care system is out of control, cost projections are beginning to approach 10% of the gross national product. A very small ...

This paper reports the results of a study to determine pattern vectors (Profiles) composed of physiological and biochemical measurements which reflect the severity of injury to traumatized individuals. Profiles, selected by clinicians at the University ...

In developing the graphics computer system BIOMOD, we were concerned primarily with the user-system interface. Rather than developing a formal higher-level language specific to modeling in biology, it appeared more fruitful to examine empirically the ...

Modeling, as we use the term here, means matching a set of numbers, obtained from some theory, to a set of numbers from the laboratory. We will refer to the laboratory numbers as the observed data or curve and to the theoretical numbers as the computed ...

Advances in computer technology have come a long way in the past twenty years. By far and away, the largest use of the computer is as a data bank for accounting, inventory and other such type business record keeping procedures. Only recently has man ...

Comments from the editors

To determine the current status of some of the work being done by our readers I have put together a questionnaire. The questionnaire itself will be found following this short note. I would appreciate hearing from all persons ...
