X-ray television

X-ray television is a method that combines the capabilities of radiography and television. It allows you to obtain high quality images using X-rays and transmit them to a TV screen.

X-ray television is widely used in medicine to diagnose various diseases. For example, using this method you can identify tumors, cysts, kidney stones, bone fractures and other pathologies. X-ray television is also used in dentistry to diagnose caries and other dental diseases.

One of the main advantages of X-ray television is the ability to obtain images in real time. This allows doctors to quickly and accurately diagnose diseases and make treatment decisions.

In addition, X-ray television has high accuracy and sensitivity, which makes it possible to detect even small changes in tissue. Thanks to this method, it is possible to carry out early diagnosis of diseases and prevent the development of complications.

However, like any other diagnostic method, X-ray television has its limitations. For example, it cannot be used to examine soft tissues such as skin and muscle. In addition, some diseases can only be detected using other diagnostic methods, such as ultrasound or computed tomography.

In general, X-ray television is an important tool in medicine and can improve the quality of diagnosis and treatment of patients.

An X-ray television device (RTV) is designed to obtain basic images on the screen of a television tube. pathologies of the chest organs.

When examining a patient, an image of the anterior wall of the chest, posterior, right and left appears on the RTV screen, as well as a view in the supine and lateral position. Following the increase in the field of view, 4 “sights” appear, including the upper left part of the radiograph, 2 in the middle part and the upper right and lower left. An image of the heart is also displayed on the screen - a direct projection, two “clavicular” and one - sagittal - obliquely from top to bottom. The latter helps to determine the elongation of the esophagus and helps to identify hyperkinesis of the diaphragm. When examining the body “to the waist,” the heart and aorta are not currently examined: in order to clearly see the second field of the PTV, the patient’s attention cannot be diverted from focusing on the arms raised up. It is very important to have good screen lighting when conducting research. For successful work, it is necessary to develop a conditioned reflex of constant readiness to respond at the first signs of detection of pathology. Late detection of pathology during X-ray examination of the abdominal and pelvic organs is due, first of all, to a lack of osteoarticular framework. All the experimenter’s commands are carried out indirectly, through the patient, who is in a state of tension. The effort is caused by the thought of the doctor - the person who carefully examines and describes the X-ray data. Fixing the “rays” on the screen is of great importance. “Beam” is like a white streak emerging from the connection of a beam of hard (X-ray) radiation and a phosphor. The rays go to the screen along guides. The distance is regulated by a guide, by moving which the experimenter stops all rays when the research technique deteriorates (the appearance of a “hidden”, previously absent manifestation) or a more superficially located pathological focus is detected. One of the beams can be erased when the projection plane of the lens surface is contaminated with a solution that sharply reduces its transmittance, especially when the rigidity of the “beam” decreases (reduction in film thickness). Such “ray dirt” noticeably disrupts the clarity of the picture due to the heterogeneity of the light flux. However, many types of CT or MRI have several advantages over radiography: •
