Radiography from two slightly different angles to simulate the distance between the viewer’s eyes (usually 4 in.) so that a stereoscopic effect is produced when the radiographs are viewed through a stereoscope.
A radiographic procedure characterized by the acquisition of two consecutive films in quick succession, each captured from a predetermined angle of projection. This deliberate variance in projection facilitates the creation of a three-dimensional visualization of a specific area of interest. The total displacement between the two films, known as the stereo shift distance, is set at one-tenth of the distance between the target and the film. This technique is commonly referred to as a stereoscopic examination, allowing for enhanced depth perception and spatial comprehension.
