The complications are divided into primary and secondary complications. An unmistakable relation to immunosuppressive medication was established in both groups.

Radiobiological considerations in multifraction irradiation. 多段辐照的放射生物学考虑。
Radiologia clinica Pub Date : 1978-01-01

{"title":"Radiobiological considerations in multifraction irradiation.","authors":"H D Kogelnik,&nbsp;H R Withers","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The initial shape of a cellular dose-survival curve is a factor of major importance in determining radiotherapy responses. It is probable that survival curves for mammalian cells exposed to X- and gamma-rays, as well as higher LET beams have an initial exponential region after which they bend downwards. The slope of this initial segment of the curve, and more importantly, the width of the shoulder before it bends significantly are the subject of the investigations to be reported. Because of the difficulty in measuring the biological effects of low doses of radiation--particularly in vivo--we have used multifraction experiments to determine the effects of the fractional doses. Such studies help determine the width of the shoulder and, with less precision, the slope of the initial part of the curve. The tissues we have studied include the bone marrow, testis, fibrovasculature, transplantable tumors, and the gastrointestinal tract. The results will be presented and some of the difficulties in their interpretation will be discussed.</p>","PeriodicalId":76405,"journal":{"name":"Radiologia clinica","volume":"47 5","pages":"362-9"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11905491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system has been designed to enable busy clinicians to retrieve and analyze data directly without major involvement of a computer specialist.

The other important feature of the system is its ability to analyze clinical data in the form of tables, frequency distribution, etc. It may also furnish actuarial characteristics of the total population or subpopulations.

With the aid of the computer, it is possible to elaborate quickly for each treatment isodose plans sufficiently accurate for practical application. The dose distribution depends on the following factors: number of fields or rotation angle, size of the radiation fields, electron energy, curvature of the body surface and shape and composition of the organs. With the aid of the computer, which is capable of simulating a multiple-field or moving-beam irradiation by the summation of the dose values of two or more single fields, the above-mentioned parameters can be changed as required and thus various types of treatment plans can be prepared.
