Radiation Therapy
Features of irradiation methods and techniques in the treatment of non-tumor diseases

Before initiating Radiation therapy, an individualized Treatment plan is developed for each patient, which includes:

1. Patient preparation for radiation therapy.

2. Precise Determination of the Location and dimensions of the pathological focus.

3. Formulation of the radiation therapy plan (Selection of irradiation Methods and techniques).

4. Determination of concomitant treatments (such as pharmacotherapy or surgery).

5. Ensuring radiation Protection of the Gonads and healthy Tissues surrounding the irradiated area.

For acute Inflammatory Diseases, the total focal dose typically ranges from 0.6-1.0 Gy, for subacute conditions from 1.0-1.5 Gy, for chronic conditions from 2.5-3 Gy, and for degenerative-dystrophic conditions from 4-6 Gy per course of treatment. This dose is delivered to the pathological focus in fractions using the following single focal doses: for acute inflammation, 0.1-0.2 Gy; for chronic inflammation, 0.3-0.5 Gy; and for degenerative-dystrophic diseases, 0.5-0.7 Gy.

Acute inflammatory processes in the infiltration phase are irradiated with intervals of 1 to 3 days between radiation therapy sessions, or daily (or every other day) if no exacerbation occurs after the first fraction. In the suppuration stage, intervals between fractions are increased to 2-3 days. In the regeneration stage, as well as in chronic inflammation and degenerative-dystrophic disorders of The Musculoskeletal System (provided no exacerbation occurs after the first fraction), irradiation is performed at one-day intervals. If an exacerbation arises, the interval between fractions is extended to 2-3 days.

For superficial dermatoses or inflammatory processes, short-distance X-ray therapy is prescribed. If the lesion is located in the subcutaneous tissue at a depth of 1.5-2.0 cm, semi-deep X-ray therapy is indicated. When the process is localized deep within soft tissues (e.g., felon, thrombophlebitis, radiculitis, neuritis, Arthritis, bursitis), long-distance X-ray therapy is used. For deeply situated pathological foci (in the Abdominal cavity or spinal Column), teletherapy (gamma-ray therapy) is advisable.
