Electronic therapy

Electronic therapy is the method of radiation therapy electrons to high energies. Electronic therapy using different designs of electron accelerators.
Electronic therapy is static and movable methods of irradiation, moreover, can be used intracavitary irradiation. To limit the field of irradiation use a diaphragm or bellows, providing the field with diameter from 4 up to 12 see
Electronic therapy used in the treatment of malignant tumors located at a depth of 1-6 cm (cancer of the skin, lips, mouth, cervix, larynx, relapses and metastases of breast cancer and other). The irradiation field of large size, the appropriate use of lead lattice with a ratio of 55 : 45, of a thickness of 7 mm, with round holes with a diameter of 5 mm With daily exposure without lattice single dose of 400 to 500 glad and General 5,000 to 6,000 happy. Therapeutic effectiveness of the method is very high.

E-therapy - treatment by the flow of electrons accelerated to high energies. Electronic therapy utilizing electrostatic generator van de Graaff (see Electrostatic generator), the betatron (see) and linear accelerators (see electron Linear accelerator). Modern settings allow you to get the electrons of different energies. Depending on the localization of the pathological education spend irradiation by electrons with energies from 1.5 to 40 MeV. When electronic therapy using methods of external and internal irradiation (see Radiation therapy).
Electrons with energies of 1.5-4.0 MeV used for the treatment of superficial angioma and keloids, Kaposi's sarcoma, fungoides mycosis, enlarged lymph nodes with leukemia, vulvar cancer, metastasis breast cancer in the skin, cancer of the upper jaw and throat. In dermatological practice, when necessary, to influence large body surface particular value acquired method of mobile electronic therapy (traveling table on which the patient lies, moved in the direction of the long axis of the body). Due to the severe restrictions of the electron beam depth e-therapy allows to spare underlying tissues under irradiation.
Beams of electrons with energies of 10 - 40 MeV used to treat cancer of the cervix, lung and esophagus, and intracranial benign and malignant tumors of glial number. Applied doses normally used in the practice of gamma and x-ray therapy (see Radiation therapy).
Electronic therapy extend when using arrays, limiting the impact of radiation on top of the fabric.
The distribution of absorbed dose of radiation to the tumor and the optimal ratio of focal and integral doses can occur if this dose is in the range 70% isodose line.
With deep location of the tumor (7 cm) suitable combined application of electron and bremsstrahlung beams (see Bremsstrahlung, Electron radiation).
