The Importance of Accurate Measurement in Scoliosis Radiography
Scoliosis diagnosis and Cobb angle monitoring are medical processes that require millimeter-level precision. In radiological imaging, factors such as patient height, X-ray tube distance, and detector placement can cause magnification errors in the captured X-ray image.
To calibrate these magnification errors digitally in a computer environment, a radiographically visible reference ruler must be placed next to the patient's spine during the X-ray shooting.
How Does a Lead Ruler Work?
A scoliosis lead ruler features millimeter-level lines made of thin lead materials that completely block X-rays. When X-ray exposure occurs, these lines show up as high-contrast and clear markings on the X-ray film or digital detector screen.
Orthopedic specialists and radiology technicians use these clear lead reference lines as a base to calibrate the image to a 1:1 scale in the software and measure spine curvature with zero margin of error.
