DOWNLOAD EBOOKWhen compiling the present atlas our aim has been to provide the practis ing radiotherapist with a handbook which would help him to plan the radiation therapy of tumours of individual organs. Apart from a few ex ceptions, all isodose charts in this atlas show dose distributions resulting from external irradiation. Combination of external irradiation with intra cavitary radium therapy is presented in the treatment of carcinoma of the uterine cervix, in which case the two techniques are complementary. Thd immense material of the pertinent literature could, naturally, not have been included in the atlas. As a result of scrupulous selection, the isod-.:se charts shown may not invariably be the optimum ones, and some of them may not be the most modern. However, the usefulness of the information they provide has made us to keep them all the same. We did not intend to change the original charts in any way and stan dardization of the isodoses was not undertaken. Radiation parameters are given in the figure captions and, if available, information has also been provided on the phantoms used by the authors. Naturally, the isodoses presented will not automatically apply to all situ ations and all apparatuses without due attention to the individual patient ::Jnd technical details such as penumbra and source diameter. They merely serve as a starting point and will help to save time and work during treat ment planning also with the computer.

DOWNLOAD EBOOKAdvances in Biological and Medical Physics, Volume III is a collection of papers dealing with the applications of radioactive isotopes, particularly, with the dosimetry of artificial radioactive isotopes, and the kinetics of the turnover of radioactive substances. One paper explains dosimetry in medicine as regards (1) units and absolute dosage rates, and (2) the distribution of radiation in a scattering medium such as the human body. The investigator can use tracers to make individual observations of the behavior of specific molecules in steady state systems. This feature of tracer applications leads to analysis of biological reaction kinetics. Some papers discuss the mechanisms involved in the antigen-antibody reactions, molecular analysis using fast charged particles, x-ray microscopy, ultraviolet microscopy, microspectroscopy, as well as the biological effects of ultrasonic waves. Ultrasonic waves can affect biological material through heat action, mechanical action, or chemical action. One paper suggests that cell disintegration is due to the mechanical effect provoked by cavitation and that cells are probably broken down by the sharp-fronted shock wave resulting from the collapse of cavitation bubbles. The collection can prove beneficial for biochemists, micro-biologists, bio-physicists, cellular researchers, and academicians involved in the study of cellular biology.
