The air-to-tissue ratio (ATR) is the ratio of radiation dose (dose rate) values ​​in tissue and in air under identical conditions. It can be used, for example, in radiation therapy, where ATR is a calculated coefficient to determine the effect of radiation on tissue.

In radiation therapy, ATR is used to evaluate the effectiveness of treatment. This is important because some types of tumors may be more sensitive to radiation than others. Thus, when planning treatment, it is necessary to take into account the ATR for each specific tumor.

ATR can be used to calculate the effective radiation dose, which is an indicator of the risk of developing radiation damage. It can also be used to determine optimal treatment parameters, such as exposure time or radiation dose.

However, it should be noted that ATR is not the only factor determining the effectiveness of treatment. It is also necessary to take into account factors such as tumor size, its location and other parameters that may affect treatment results.

Thus, the tissue-to-air ratio is an important tool for assessing the effectiveness of radiotherapy and treatment planning. However, its use must be complemented by other factors such as tumor size and location to obtain the most accurate results.

Introduction The Tissue-Air relationship is one of the basic concepts in radiation medicine and radiation safety. This is a ratio that reflects the ratio of radiation dose values ​​in body tissues and in free air. The Tissue-Air ratio is used to estimate the radiation doses received by patients and personnel from exposures resulting from diagnostic procedures, treatments, and other medical procedures.

What is the ratio of fabric? Tissue ratio is the ratio between the radiation dose a patient receives and the dose received from the same x-ray by a physician or staff. This ratio depends on many factors, including the size and density of the patient's body, as well as the distance and angles between the patient's body and the X-ray machine. To obtain the calculated dose for the patient, the dose must be multiplied by the tissue ratio. For example, if an X-ray machine produces up to 1 millisievert of radiation, the patient would need to be exposed to radiation for 2 seconds to produce a calculated dose of 5 millisieverts. In medicine, tissue ratio is widely
