Then they must the rotate them flat on the table to their side and another photo is taken. During this whole time - the dog cannot move or the x-ray will either not be readable or not in the right position to check. Then the vet must be trained to know how to read the x-rays. In some cases it takes someone that specializes in this.
When a vet feels the knees - the joint must not be too tight or too loose. I call it the Goldlocks test - the knees must feel just right.
I hope this helps.

According to this no x-rays are used. (copied and pasted from an above post)
The exam for OFA for patellas is a manual exam performed by a regular vet. No xrays are used. It is not the same as OFA'ing hips. Just an FYI. Here is the form for having patella's OFA'd:

Tghanks and I just found on the form that it is for dogs over 12 months.
