Slot-radiography is an x-ray examination in which a two-dimensional radiography with a straight beam and further computer stitching of the images obtained on the workstation during a single-pass of x-ray tube over a patient. The application of innovative techniques for image acquisition and processing in combination with a large-area flat panel detector (FPD) makes it possible to produce long-view images from one to several anatomical regions. During the investigation, the x-ray tube and the FPD move simultaneously at a constant speed in parallel relative to one another with the longitudinal axis of the body. Thus, it makes possible to obtain images with little distortion and processed images without visual defects. And this allows conducting more accurate diagnosis of pathological changes. Slot-radiography can be performed both in the patient’s standing position and lying down depending on the region of interest and tasks. It is possible to obtain images in both a frontal and a lateral projection without loss of quality.

Slot-radiography is effectively used to diagnose pathological changes in joints and spine, including scoliosis, limb shortening, segmental spinal instability, pathology of lower limb veins, and also as a method for assessing the quality of the treatment. This technique is characterized by safety and convenience for the patient: minimal time costs and low radiation exposure.

The application of this technique significantly increases the informative value of the x-ray examination, brings it to a qualitatively new level, providing a physician with a wide range of diagnostic possibilities.

Key words: slot radiography, digital radiography, flat panel detector, orthopedic surgery
