Stereoradiogrammetry

Stereoradiogrammetry (SRG) is a diagnostic method that is used to determine the shape and size of the skull bones, as well as to identify developmental anomalies. It is based on the use of stereoradiography, a method that produces three-dimensional images of the skull.

To perform an SRG, it is necessary to take two photographs of the skull - one from the front and the other from the side. These images are then combined into a 3D model of the skull using special software. This method allows you to obtain more accurate information about the condition of the skull bones than a regular x-ray.

SRG can be useful in diagnosing various diseases such as traumatic brain injury, brain tumors, hydrocephalus and others. In addition, this method can be used to evaluate the effectiveness of treatment.

One of the advantages of SRG is its safety for the patient. Unlike computed tomography (CT) scans, which can cause radiation exposure, SRG does not require the use of radiation.

In conclusion, stereoradiogrammetry is an important diagnostic method for assessing the condition of the skull bones and identifying abnormalities in their development. It can be used both in medical institutions and at home.

Stereo-radiometry is a method of X-ray examination of the internal structure of biological objects: bones, internal organs, etc. X-rays are obtained by sequentially x-raying a body divided into parts, for example, sequentially on the right and left. In order to present the parts in the correct relative position, a special device is used - a stereoscope. It is a telescope where a plexiglass disk or insert is attached to the eyepiece, covering one eye of the observer, and bent in accordance with the resulting projections. To examine individual parts of the body, they are made motionless in relation to the entire length of the body and placed under that part of the apparatus that transmits X-rays for a given area of ​​the body.

The need to study the great anatomical and morphological value of the skeleton played a significant role in the development of the method. It was important to determine the features of the microscopic structure of bone formations (individual areas in the area of ​​the walls of spongy bones).

An X-ray machine is capable of splitting radiation passing through an object into several beams (this is called splitting - an image from several sources). One of these two images from different sides can be received simultaneously and immediately interpreted. So far, this method has become almost impossible. From now on, one or two images obtained in different projections are mainly used to study the general condition of the patient to identify malformations or other pathological processes.

Radiography applies to it only when performing simple tasks. The essence is the influence on the studied area, the actions performed distort it.
