The tomography device consists of several parts. It has similarities with the MR device in terms of appearance and operation characteristics. The device has a panel, table and monitor with ultraviolet rays reflected. During viewing, these tracks run synchronously. The basic working principle of the device is that the images of the patient lying on the table can be displayed on the monitor and recorded in detail.
Imaging of the device is similar to x-ray. The panel that enters the table has a section that reflects ultraviolet rays. The rays are reflected in the desired area and the part of the body is observed with the aid of the camera. The desired section is zoomed with the camera and appears on the monitor in detail. From here it is possible to conduct a detailed examination even on a cell basis.
After the patient is admitted to the table, the table is scanned manually or by remote control so that the area of the patient to be examined is scanned. The created images can be transferred to the film and can be viewed on the computer screen as they are live. The tomography device will record each transaction as data. However, since the x-ray is used as the method, the meaning of the gray tones is the same as in the standard x-ray process.
The patient must hold his / her breath to be able to take a cross section on the tomography. Therefore, breathing exercises must be performed before imaging. While it may be necessary to wait about five minutes to get a section in the past, it is possible to take a cross section at a breath holding time thanks to the advanced technology today. The receiving section is examined and recorded in detail in a 3D form on the screen.
In some cases, a fluid known as a contrast agent can be injected into the body of the patient to allow tissue and organs to be seen. The computed tomography procedures are called medicated tomography. The injected contrast agent causes the tissue of the patient to be imaged and displayed better in the device. This method is especially applied in situations such as muscle wasting.
An average CT scan takes about 15 minutes. In this process, the portion of the body to be examined is scanned and the images obtained therefrom are transmitted to the monitor. However, in some cases the duration of the examination can be longer or shorter than 15 minutes. During this time, the device records the images and transmits them to the monitors. This review of the images taken by the health care practitioners will need to be interpreted.
