Therapy Radiation Close focus

Near-focus radiation therapy: features and application

Near Focus Radiation Therapy (LFRT) is one of the types of X-ray therapy that is used to treat malignant tumors. Unlike other methods of radiation therapy, in which the radiation source is located at a distance from the surface of the body, with LBF it is located at a distance of 5-10 cm, which allows you to concentrate the dose of rays on a small area of ​​​​tissue, which allows you to achieve high precision irradiation and minimize exposure to rays to surrounding healthy tissue.

Near Focus Radiation Therapy can be used to treat various types of tumors, including radiation to the brain, lungs, liver, kidneys, bones and other organs. In some cases, this method is used to treat recurrent tumors after other types of radiation therapy.

One of the advantages of LBF is the ability to perform the procedure on an outpatient basis, which reduces the burden on the patient and allows him to quickly return to normal life. In addition, with LBF, an accelerated course of radiation therapy is possible, which reduces treatment time.

Another type of radiation therapy that uses close-focus radiation is gamma therapy. Unlike LBF, in which the radiation source is located at a distance of 5-10 cm from the surface of the body, with gamma therapy it is removed at a distance of up to 30 cm. Previously, this method was called short-distance therapy (brachytherapy). Gamma therapy also has its advantages, including the ability to precisely focus the dose of radiation on a small area of ​​tissue.

However, despite the benefits, the use of radiation therapy can be accompanied by unwanted side effects such as fatigue, nausea, hair loss and others. Therefore, before using Near Focus Radiation Therapy, it is necessary to conduct a thorough diagnosis and evaluate the benefits of treatment compared to possible risks and side effects.

Thus, Near Focus Radiation Therapy is an effective method for treating malignant tumors, which allows one to achieve high precision irradiation and minimize the impact of rays on surrounding healthy tissue. However, it is necessary to keep in mind the possibility of side effects and conduct a thorough assessment of the benefits and risks before starting treatment.

Near Focus Radiation Therapy

Close focus radiation or brachytherapy is a method used in medicine to treat various diseases such as cancer, sarcoma and some others. This method is based on the use of radiation treatment using special doses of radiation that are applied directly to the affected area.

How does brachytherapy work?

Brachytherapy uses special devices called radiological applicators, to which special blocks containing a source of ionizing radiation are attached. The units emit low-dose X-rays or gamma particles that are aimed at a small area located near the painful area. This allows high-intensity radiation therapy to directly target the affected tissue.

Application of brachytherapy

Brachemotherapy is used to treat cancer of the prostate, testicles, larynx, cervix and some other malignant tumors. It is also used to treat soft tissue and bone sarcomas, as well as some other diseases. Treatment can be performed remotely while lying down or sitting, which helps protect healthy nearby tissue from harmful radiation.

Negative aspects of brachemotherapy include the risk of side effects such as early childhood growth, hair loss, nausea, vomiting, temporary loss of function of various organs, and so on. In addition, its use can be quite expensive and requires rapid treatment decisions.

The development of new technologies is key to increasing the effectiveness of therapy and reducing the likelihood of severe side effects.
