Device design and scope
With the help of negatoscopes, medical personnel can view dry and wet images.
The uncomplicated design is a rectangular plastic or steel case with a white acrylic glass screen. Inside are LED or fluorescent lamps. Due to the dullness of the screen, bright light is softer and viewing pictures is much more comfortable. Also, almost all models provide a regulator of the intensity of the glow of the lamps.
For attaching dry pictures, special clothespins are provided, and wet ones are easily glued directly to the glass. Depending on the model, the negatoscope is installed horizontally or vertically.
Application area
The range of medical areas in which a radiograph is required for a diagnosis is quite wide. And therefore, in clinical practice in the relevant departments, the negatoscope is a necessary device.
These areas of medicine include:
- angiology;
- vertebrology;
- gastroenterology;
- gynecology;
- cardiology;
- mammalogy;
- neurology;
- nephrology;
- oncology;
- otolaryngology;
- pediatrics;
- pulmonology;
- resuscitation;
- rheumatology;
- dentistry;

Thanks to X-ray images, doctors have the opportunity to identify diseases of various organs and systems.
Classification of negatoscopes
There is a large selection of negatoscopes on the medical equipment market today. All devices can be divided into several groups, depending on the individual characteristics of the model.
By type of lamps:
- halogen;
- luminescent;
- LED;
- fluorescent.
By mounting method:

- Four-frame. Doctors get the opportunity to study up to four images at a time.Such devices also have a function of frame-by-frame switching, which allows you to see the dynamics of treatment and make a decision about further actions.
In addition to all of the above, there are also non-standard models that are used in such areas of medicine as, for example, mammology or dentistry.
Criterias of choice
Depending on the quality of the device, the radiologist receives more accurate information about the patient's health. Therefore, the choice of a negatoscope should be treated with full responsibility and the following parameters should be taken into account:
- The higher the brightness of the lamps, the more information the doctor will receive from the picture;
- The presence of moving shutters makes it possible to view the images in detail;
- The dimmer allows you to choose the most suitable conditions for studying the radiographs of certain organs;
- The glow color should be of a cold white spectrum;
- Uniform illumination creates a comfortable environment for the eyes;
- The screen size determines the ability to study from one to four images at a time;
- Models with an LED light source are free from the flicker effect, which helps to reduce eye strain;
- It is better to choose models powered by the network. They are less mobile, but more reliable in operation and less energy consuming.
As for the material from which the body of the device is made, the plastic construction is certainly lighter, but the steel frame is stronger and more efficiently protects the screen from accidental impacts.
When choosing a negatoscope, it is also important to build on the tasks that will be solved using the device.
