Photodosimetry

Recently, dosimetry and photodiagnostic methods in medicine have become increasingly important. This is due to the increasing availability of equipment and technical capabilities, as well as the expansion of applications. In particular, photodiagnostics is used in phototherapy, laser therapy, electrotherapy, etc. It should be noted that the correct use of dosimeters and photodetectors is an important component of quality patient treatment and obtaining optimal results.

What is photodosing and what does it involve? Photodosing is the process of assessing the dosage of radiation from a light source that is at sufficient power to carry out a certain procedure. Measuring the degree of power of a light source is an integral part of the registration process of photomethods, and the quality of registration of the photogram and the results of the photodiagnostic examination depend on the accuracy of the measurement.

In modern medical photometry, equipment is constantly updated and improved, which can significantly improve the accuracy of diagnosis, reduce examination time and increase the safety of using this method for the patient. Thus, dosimeters and photodetectors have become an integral part of photometric systems that make it possible to record not only the light dose from the light source and the optical intensity

Photodosimetry (from the Latin - "pho" - photo and "dose" - dose) should be considered as a physiotherapeutic method of local action, the purpose of which is the use of high-energy electromagnetic waves for the purpose of healing, prevention and treatment of a number of diseases by reducing (suppressing) the pathological factor. The therapeutic physical effect is based on the mechanism of anti-cancer defense of the human body caused by low-intensity stress, i.e., suppression of mutator cells associated with genome rearrangement, replacing the affected one in a normal cell. Suppression of cancer mutator cells differs from methods of morphological correction, ontogenetic gerozo

In modern medicine, it is not always enough to simply analyze the results of an examination. Photodosing allows you to evaluate the ratio of various human tissues, their response to various factors, so the technique provides high accuracy. Unlike simple dosimetry, it helps to study the body's reactions to radiation, i.e. provides more complete information about the effects of this method of exposure on the body.

The physical principles for photographic imaging are based on the use of light waves and the effect of light on living tissue, which allows obtaining an accurate amount of radiation and its uniform distribution on the patient's body. The photographic image allows you to make accurate measurements of such indicators as intensity, penetration depth, and the nature of the distribution of radiation throughout the body.

The method consists of two main stages. The first is obtaining a light image of specified areas of the patient’s body. This occurs due to the processing of a special system for controlling the flow of radiant energy and the subsequent connection of the resulting image in the form of pixels or in computer form. The second stage is the conversion of the color components of the pixels into time and/or digital components of the rays or their digital conversion and transfer of information through serial data transmission. Using photodosing, you can quite accurately predict the expected effectiveness and dose of treatment. It is also possible to use the method in treatment to eliminate identified disorders. Thus, photodosing uses the physical principles of the emitter to optimally treat patients, who may differ in individual characteristics of appearance, such as physique, age, and health status. The result of obtaining accurate readings using images allows clinicians to carry out highly accurate treatment control in accordance with specific parameters, and study patient complaints based on certain parameters.

Photodosimetry is a method that can accurately determine the radiation dose a patient receives when using medical equipment such as x-rays or radiotherapy. This method uses photometers and other instruments to measure the amount of light that passes through the patient's body and stops at the surface of the skin or other organ exposed to radiation.

A photometer is used to measure the level of light or color. A photodosimeter can also be used to measure physical dose from certain radiation sources, such as X-rays or gamma rays. In physiotherapy and cosmetology, photodosimeters are used to monitor the effectiveness of therapy and control the dosage of radiation.

It is important to note that photodosing is an important part of ensuring patient safety and protecting staff from radiation exposure. This helps ensure that patients receive enough dosage to achieve a therapeutic effect, but no more than is necessary for protection.

In conclusion, a photodosimeter is an important tool in the world of physical therapy, medicine and other medical and technological fields. Its use makes it possible to more accurately control the radiation dose received and ensure the safety of patients and staff.

Relevance of the topic: Patients receiving treatment with medical equipment using radiation or magnetic waves often ask what a photodosimeter is and why it is so important for their health. Today we will tell you how such a small thing plays a significant role in maintaining the health and well-being of patients.

Basic principles of photodosimetry

The first thing to know is that photodose measurement is the process of measuring the amount of energy absorbed by X-rays or another form of radiation at the surface of tissue. This may seem simple, but in practice this measurement is a key element of modern radiation treatment. For example, if X-rays are not measured and calculated correctly, this can lead to errors in tumor location. As a result, they may be displaced or miss the tumor, which can reduce the effectiveness of treatment. To address this issue, it is important to continually monitor and measure the amount of radiation energy absorbed to ensure that the patient receives the right amount of radiation where needed, and where it never exceeds acceptable safety levels.
