radiographic magnification

radiographic magnification

a procedure used to improve visualization of fine blood vessels and small bony structures during x-ray imaging. Magnification is achieved by increasing the distance of the object from the radiographic image receptor or by decreasing the distance of the x-ray source from the image receptor.

This relatively small difference may be explained by radiographic magnification as well as potential gravitational effects during myelography.
12 Some other factors like radiographic magnification errors, overestimation of canal length make the working length measurement unreliable13 therefore solely relying on radiograph for working length determination is dubious.
