[Distribution of absorbed dose of electron beams from a linear accelerator of 8-17.5 MeV energy]. / Raspredelenie pogloshchennoi dozy élektronnykh puchkov lineinogo uskoritelia s énergiei 8-17.5 MéV>

The authors presented some experimental and theoretical data on dose distribution in a tissue equivalent phantom during irradiation with electrons at 8; 10; 12.5; 15 and 17.5 MeV. The proposed mathematical apparatus based on the method of dose functions of a punctate unidirectional source, can be used for the development of programs of dosimetric planning of electron therapy using the LUEV-15MI accelerator.

[Use of bremsstrahlung and electron beams in the preoperative irradiation of breast cancer with figure fields]. / Ispol'zovanie puckhov tormoznogo i élektronnogo izluchenií v predoperatsionnom obluchenii raka molochnoi zhelezy figurnymi poliami.

Under consideration are the problems of preoperative radiotherapy for breast cancer patients with the use of 27 Mev electron beams and 17.5 and 27.5 Mev accelerator LUE-25 braking radiation. The methods for shaping figure fields was elaborated taking into account some individual anatomical features to provide simultaneous irradiation of all areas of regional metastases. Clinical testing of the suggested method for fast electron beams has demonstrated the treatment to be adequately tolerated and also the absence of grave reactions during it as well as of the immediate and early radiation complications. The time of preoperative radiotherapy was made twice shorter.
