Tumor Response Monitoring and Treatment Planning
Medical imaging progressed to a standard undreamt of not very many years ago. The advances are due to continuous development of radiological techniques and the introduction of magnetic resonance imaging. With the improved and new methods three-dimensional target volumes for radiation therapy can be defined with hitherto unknown precision. This leads to an improvement in irradiation techniques and, as a consequence, to a higher likelihood of tumor control and a lower risk of normal tissue complications. Besides the improvement in irradiation techniques the new imaging methods may enable great strides in tumor response monitoring, not only in the detection of morphological alterations but also by showing physiological changes in the tumor during and after treatment by means of MRI and PET. This not only leads to better prognostic information but may also allow early evaluation of the response to treatment. It may then be possible to individualize the radiation dose but also the alternative-treatment for non-responders. This is certainly a future direction for radiation oncology.
Three-dimensional Radiation Treatment
Radiation therapy is in the process of continual change, fueled by advances in computer technology, but also aided by the contributions of several disciplines such as physics, mathematics, radiological diagnostics, neurosurgery, and mechanical and electrical engineering. Based on the 3D imaging techniques CT and MRI, a complete change from the 2D consideration of the radiotherapy problem has taken place, leading to 3D treatment planning and to completely new treatment delivery systems. A 3D approach allows for a dramatic rethinking of the following central therapy issues: positioning, targeting, and dose and risk calculation. Major advances have been made in recent years in conformal or ster...
World Congress on Medical Physics and Biomedical Engineering September 7 - 12, 2009 Munich, Germany
Present Your Research to the World! The World Congress 2009 on Medical Physics and Biomedical Engineering – the triennial scientific meeting of the IUPESM - is the world’s leading forum for presenting the results of current scientific work in health-related physics and technologies to an international audience. With more than 2,800 presentations it will be the biggest conference in the fields of Medical Physics and Biomedical Engineering in 2009! Medical physics, biomedical engineering and bioengineering have been driving forces of innovation and progress in medicine and healthcare over the past two decades. As new key technologies arise with significant potential to open new options in ...

Theoretical Aspects and New Developments in Magneto-Optics
The Advanced Study Institute on "Theoretical Aspects and New Developments in Magneto-Optics" was held at the University of Antwerpen (R.U.C.A.), from July 16 to July 28, 1979. The Institute was sponsored by NATO. Co-sponsors were: Agfa-Gevaert (Belgium), A.S.L.K. (Belgium), Bell Telephone Mfg. CO. (Belgium), Esso Belgium, Generale Bankmaatschappij (Belgium), General Motors (Belgium), I.B.M. (Belgium), Kredietbank (Belgium), Metallurgie Hoboken-Over pelt (Belgium), National Science Foundation (U.S.A). A total of 60 lecturers and participants attended the Institute. Scope of the Institute The magneto-optic phenomena are due to the change of the polarizability of a substance as a result of the splitting of the quantized energy bands. Most of these phenomena were discovered during the second half of this century. The understanding of the magneto-optical effects of all kinds, however, was brought by the advent of quantum mechanics, and since then important progress has been made in many fields of experimental methods and techniques.
Ultrafast Phenomena in Semiconductors
There are many books in the market devoted to the review of certain fields. This book is different from those in that authors not only provide reviews of the fields but also present their own important contributions to the fields in a tutorial way. As a result, researchers who are already in the field of ultrafast dynamics in semicon ductors and its device applications as well as researchers and graduate students just entering the field will benefit from it. This book is made up of recent new developments in the field of ultrafast dynamics in semiconductors. It consists of nine chapters. Chapter 1 reviews a mi croscopic many-body theory which allows one to compute the linear and non-linear o...
Semiconductor Interfaces and Microstructures
Recently there have been major achievements in the study of semiconductor interfaces and microstructures for different materials and structural systems. Progress has been made through various experimental technologies and theoretical methods. This book provides an up-to-date review on these advances and includes the following major subjects: IV-IV, III-V and II-VI semiconductors and metal/semiconductor structures; new developments in growth methods; electric, optical, magnetic and structural characterization and properties; relative theories — electronic transport, phonos and interface modes; devices and applications. These materials are organized into four sections: General, III-V, II-VI ...
Nondestructive Evaluation of Semiconductor Materials and Devices
From September 19-29, a NATO Advanced Study Institute on Non destructive Evaluation of Semiconductor Materials and Devices was held at the Villa Tuscolano in Frascati, Italy. A total of 80 attendees and lecturers participated in the program which covered many of the important topics in this field. The subject matter was divided to emphasize the following different types of problems: electrical measurements; acoustic measurements; scanning techniques; optical methods; backscatter methods; x-ray observations; accele rated life tests. It would be difficult to give a full discussion of such an Institute without going through the major points of each speaker. Clearly this is the proper task of the eventual readers of these Proceedings. Instead, it would be preferable to stress some general issues. What came through very clearly is that the measurements of the basic scientists in materials and device phenomena are of sub stantial immediate concern to the device technologies and end users.
Solid Surfaces, Interfaces and Thin Films
This book emphasises both experimental and theoretical aspects of surface, interface and thin film physics. Compa- red to the earlier editions, which bore the title "Surfaces and Interfaces of Solid Materials", the book now places more emphasis on thin films, including also their superconducting and ferromagnetic properties. The present 4th edition thus presents techniques of preparing well-defined solid surfaces and interfaces, fundamental aspects of adsorption and layer growth, as well as basic models for the descripti- on of structural, vibronic and electronic properties of sur- faces, interfaces and thin films. Because of their importan- ce for modern information technology, significant attention is paid to the electronic properties of semiconductor inter- faces and heterostructures. Collective phenomena , such as superconductivity and ferromagnetism, also feature promi- nently. Experimental sections covering essential measurement and preparation techniques are presented in separate panels.
