Radiographic reference ball

Radiographic Reference Ball - 25mm

The Radiographic Reference Ball is 25mm in diameter and is attached to a stable base by a flexible neck which allows the ball to be placed at the same level above the plate as the area of interest. Using a spherical object as a reference eliminates errors created by ruler type reference which might not be quite parallel with the plate.

When using the radiograph for templating implants eg. a total hip replacement, it is very important to make accurate measurements. As taking radiographs where the area of interest is not close to the plate can create some challenges in scaling, the reference ball will make the measuring process easier/more accurate.
