To develop and promulgate internationally accepted recommendations on radiation related quantities and units, terminology, measurement procedures, and reference data for the safe and efficient application of ionizing radiation to medical diagnosis and therapy, radiation science and technology, and radiation protection of individuals and populations. ABSTRACT Operational, measurable, quantities for external radiation protection complement the protection quantities, which are,by their nature, not measurable.

Chapter 7 : Clinical Treatment Planning in External Photon Beam Radiotherapy

The proposal of this study was to reproduce the dosimetry established by a treatment planning system TPS following a 3D conformational radiation therapy 3DCRT protocol of two parallel-opposite fields applied to the left-breast in a thorax phantom, with the complementary use of the field-in-field technique. The computed tomography CT images of the thorax phantom were transferred to the XiO version-5 for the elaboration of the breast teletherapeutic planning with 2 Gy per day, in 25 fractions, with prescribed dose of 50 Gy. A set of ten EBT2 radiochromic films were irradiated at doses gradually. The values of RGB Red, Green, Blue of the films were obtained by scanning and data transformed in optical density OD , whose values were used to construct the calibration curve. Radiochromic films were positioned outside and inside of the thorax phantom.

 Энсей Танкадо… родился в январе… - Пожалуйста, - вежливо сказал Беккер.  - Положите на место. Офицер еще какое-то время разглядывал паспорт, потом положил его поверх вороха одежды. - У этого парня была виза третьего класса.

Установленная на треноге картонная табличка с надписью OFICINA стрелкой указывала направление. Беккер двинулся по едва освещенному коридору. Все здесь напоминало зловещую декорацию к голливудскому фильму ужасов. В воздухе стоял тяжелый запах мочи. Лампочки в конце коридора не горели, и на протяжении последних двадцати метров можно было различать только смутные силуэты.

Неужели все это был сон. Сьюзан повернулась к тумбочке. На ней стояли пустая бутылка из-под шампанского, два бокала… и лежала записка.

Оставался последний номер. Конец веревочки.

    This extensive publication covers different relevant aspects of stereotactic radiotherapy such as small field dosimetry, accuracy requirements for volume definition and planning algorithms, and the precise application of treatment by means of image guidance.
