Beginning in the early days of the Space Age - well before the advent of manned spaceflight - the United States, followed soon by other nations, undertook an ambitious effort to study the planets of the solar system. The remarkable fruits of this research revolutionized the public's view of their celestial neighbors, capturing the imaginations of people from all backgrounds like nothing else save the Apollo lunar missions. From the first space probes to the most recent planetary rovers, they have continually delivered impressive discoveries and reshaped our understanding of the cosmos. Offering fascinating investigations into this crucial chapter in space history, this collection of specially commissioned essays from leading historians opens new vistas in our understanding of the development of planetary science.

The problem of automatically extracting map symbology from source imagery is studied. It is concluded that a great deal of geographic knowledge used by humans, who currently perform this extraction function, must be made available to machines before the function can be automated. Several geographic knowledge sources are discussed and an attempt is made to define paradigms under which knowledge can be encoded and used in the computer. An automatic cartographic feature extraction system (ACES) is sketched which represents a best framework for continuing development on this difficult problem given current achievements. A systems approach is taken with first consideration given to desired outputs and available inputs. It is concluded that input/output technology is far in advance of technology available for interpretation of the data. Emphasis is placed on the use of knowledge by ACES during automatic interpretation of imagery. Many types of knowledge typically used by humans appear difficult to engineer into automatic processes. Use of positional knowledge encoded in a geographic data base (GDB) is selected as the most promising avenue. Proposals are given for future research work in that direction. (Author).

According to Schopenhauer problems are usually passing through three stages: - in the first stage they are ignored or just smiled at, - in the second stage they are fought, and in the third stage they are considered to be self-evident, just taken for granted. Whereas digital subtraction angiography (DSA) has obviously reached stage three of that scale, i.e. routine use in radiology, digital angiocardiography, in particular imaging the heart and coronary circulation, is still on its way to the final goal: the filmless heart catheterization laboratory for all invasive and interventional procedures. A few pioneers have already completely abandoned the conventional cine coronary and angiocardiographic technique, others - as we do -still combine both digital and conventional methods in clinical routine, but most cardiol ogists up till now stay sceptically aside. We hope that at least some of the articles published in this volume may convince more and more cardiologists that digital imaging procedures are the method of choice, in particular if quantitative assessment of the anatomical or functional status of the cardiovascular system is required (pre- and post operations or pre-and post-interventions). Such a critical control of all therapeutic procedures, be it by surgical, catheter-or medical 'interventions', is indeed an urgent and widely under estimated or neglected requirement.

In recent years there has been an increasing interest in quantitative analysis of coronary cineangiograms and already for a longer time of left ventricular cin eangiograms. The needfor quantitationofcoronary arterialdimensions has been stimulated by the introduction ofnew therapeutic procedures in the catheteriza tionlaboratory, suchas the balloon dilatationtechnique (PTCA) and thromboly tic therapy, by the need to study the vasoactive responses of pharmaceutical agents, and also by the desire to study the progressive nature ofcoronary artery disease with the ultimate goal to find ways to bring a halt to the progression of coronary atherosclerosis or even achieve regression of the disease. Parallel with these clinical developments, rapid technical developments in computerarchitect ures and semiconductor memories have made it possible to digitize and store cineframesor selected portions thereof in image processors and to analyze these pictorial data quantitatively at affordable prices. More than 15 years of research have been directed by various groups towards the semi- or fully-automated delineation of the left ventricular boundaries on a frame-to-frame basis. Yet not a single system with fully-automated capability is commercially available. In the mean time many different left ventricular wall motion models have been developed, again with little consensuson which model is to be preferred as no golden standard exists.

Over the past twenty years, technical advances in coronary arteriography have contributed to our understanding of the pathophysiologic aspects and natural history of coronary artery disease. Probably more than 700. 000 coronary arterio grams are performed annually throughout the world. Usually, these arteriograms are interpreted visually to determine the morphologic extent and severity of coronary artery disease. These subjective determinations, which are hampered . by relatively large intra- and interobserver variations, are used as a basis for critically important therapeutic decisions: Which arteries are to be revascular ized, which lesions are suitable for coronary bypass surgery or for percutaneous coronary angioplasty? To improve on this clinical decision making, on the treat ment and follow-up of such patients, new, objective and reproducible techniques for the assessment of the extent and severity of coronary artery disease, both in terms of anatomy and functional significance of the lesions, must be made widely available. With such new procedures and technologies the efficacy of new thera peutic procedures, the effects of vasodilating and constricting drugs, and the results of long-term studies on the regression and progression of atherosclerotic plaque can be determined in an objective and cost-effective manner.
