Craig is planning to add this type of broad comparative calculation ability in the future. Photography Considerations Ideally, hoof photographs for the database are taken when the horse is being shod, because measurements are more accurate if the horse is barefoot. This is a distance that the person taking the radiograph knows. This method certainly is adequate for general use, whereas for research, the specifics can be further refined for enhanced accuracy. A major consideration in using any image analysis program is how the photograph is set up.
Measurement can be accurate only if the surface to be measured is perpendicular to the camera.
However, as long as the user is consistent, there is a small enough margin for error that results still will be relevant. These measurement programs could be used to prove or disprove theories about trimming and shoeing, and how differences in trimming and shoeing affect the overall health of the horse. This software will help give substance to the things we really see. Vets will be more able to compare changes in the horse's hooves between visits, as owners don't usually have access to radiographs. Also, more people are starting to demand more from the vet in terms of a diagnosis.
