It is well known that x-rays used for surgical planning vary in magnification. This variation exists in part because of the diversity of techniques used by x-ray technologists, patient positioning, and the patient’s size. Even with strict imaging protocols, the magnification of an x-ray image can vary. A thin patient lying on an imaging receptor is only a few inches above the plate, giving little distance for the X-rays to diverge. In a larger patient, the distance may be twice as far from the plate, allowing the divergent beam to spread much more before it hits the plate. This can result in a magnification factor of approximately 20%. Scaling an x-ray image is mandatory to assure the highest level of accuracy throughout the planning process, especially orthopedic templating. Does size matter when it comes to magnification of an x-ray and surgical planning? Absolutely! Preoperative planning aims to reduce the risk of intraoperative fracture and decrease overall surgical time. Images that are used for surgical planning must be accurately scaled to allow for accurate implant selection.

Description / OrthoMark® - OM-1002 Magnetic Base Surgical Planning Marker
OrthoMark was designed over 20 years ago to help measure x-ray magnification in digital images and they’ve been doing the job since. OrthoMark is compatible with all medical, orthopedic and veterinary templating software available, and there is a solution for every x-ray room.
The magnetic base Model OM-1002 is designed for use on ferrous surfaces.
Simply attach it to your surface, position the OrthoMark sphere, and you’re good to go.
Position the sphere normally after positioning patient. By positioning OrthoMark's solid, 1 inch (25.4mm) stainless steel calibration ball at the precise anatomical plane of the shoulder, hip, knee—or any anatomy for that matter—during x-ray imaging, surgical planning software is able automatically find the x-ray marker in the image, calculate the x-ray magnification factor, and determine the true size of the anatomy in question. This helps to ensure that the appropriate prosthetic is selected before surgery.
The OM-1002 can be used with all orthopedic and veterinary surgical templating software. Do not place magnets in the vicinity of computer hard disc drives or mechanical relays as they may cause damage to those components.
