X-ray densitometry Indirect

X-ray densitometry is a medical diagnostic method that is used to assess bone density. It is based on measuring the optical density of the shadow of the object under study on an x-ray image. Currently, there are several methods of X-ray densitometry, including direct and indirect.

Direct X-ray densitometry involves passing an X-ray beam through the object being examined and recording it on film or on a computer. This method is the most accurate, but requires the use of special equipment and trained professionals.

Indirect X-ray densitometry is based on measuring the brightness of the corresponding section of the fluorescent screen, which is located in front of the object under study. This method is less accurate, but it is more accessible and easier to use.

Indirect X-ray densitometry can be performed using a conventional X-ray unit. To do this, you need to install a special screen in front of the object that will be examined. The X-ray beam then passes through the object and hits a screen, where it is scattered and reflected.

After this, the brightness of the screen is measured using a photosensor. The received data is processed by a computer and displayed on the screen. X-ray densitometry allows you to determine the density of bone tissue in various parts of the body, which can help in the diagnosis of osteoporosis and other diseases of the skeletal system.

Thus, X-ray densitometry is an important medical diagnostic method that allows one to assess the condition of bone tissue and identify possible diseases. Indirect X-ray densitometry can be performed using conventional X-ray units and is more accessible and easier to use than direct X-ray densitometry.

X-ray densitometry is a method of x-ray examination of the human body by creating a negative image of the structure of tissues to assess their density. The method allows you to estimate the calcium content and bone mineral density (BMD) in the human body. Its use is advisable at the stage of primary diagnosis of various diseases of the musculoskeletal system and in determining the risk group for the development of osteopenia.
