A doctor can use a 2D image model to show where the break is.
When a patient breaks a leg (the break could be as a result of fracture or bone dislocation), the doctor needs to scan the patient in order to determine the exact location of the break and the extent of the injury.
The gamma camera, x-ray machine and PET scanners are some of the devices that can be used to scan a bone.
Each of these devices uses 2D image technology to show the result of the scan.
So, a model that can be used by a doctor to determine the location of the break is 2D image.
